Henan Hairun Germany the new swimming pool water treatment equipment, water treatment equipment, swimming pool heated swimming pool description: swimming pool filtration equipment, swimming pool water treatment equipment, swimming pool water purification equipment, swimming pool filtration equipment for the first time. Gravity automatic seven-efficient fine filter series of water treatment equipment, are specially designed for swimming pool water purification treatment equipment, also known as gravity valveless fine filter, gravity water conservation and efficient automation fine filter is Our introduction of international advanced product design, research industry drawbacks of conventional devices, is an analog bionics theory developed products. Is currently the most advanced, most energy-efficient pool water purification equipment. Main features: swimming pool engineering technology has its own characteristics, which requires a pool of specialized technology, special equipment, which created a highly professional pool industry, which in particular in: 1. Swimming pool water circulating filter is recycled water disinfection use, water circulation and repeatedly recycling, that is, the water (no matter how high filtration precision and purity) filtered and treated water containing contaminants continuously fed unfiltered, making mixed voicing water meet health standards, and then continue to pollute the water and then a continuous cycle, filtration, clarification and disinfection; and because the swimmers and around the outside to the pool into pollutants pool self bacteria and algae, so the water is constantly polluting; circulation, filtration, disinfection, clarification, pollution in a dynamic equilibrium. This dynamic is reflected in the unstable, fluctuating water temperature, chemical dosing changes, changes in the number of circulating flow swimming and so on. 2. Swimming pool water characteristics (physical) treatment is circulating filtration, water treatment works in other less relevant issues to consider, such as loops and cycles, as well as to the outlet, the back to make the uniform distribution outlet water distribution problems, dead zones and issue short stream. 3. The continued pollution and instability, requiring continuous filtration and continuous disinfection. Physical treatment and chemical treatment of water quality at the same time. Also pay attention to the structure of the cell body and a reasonable selection and layout of a circular manner, and swimming pool equipment and fittings. 4. To ensure the safety of swimming pool water, health, economic, scientific, reliable, low-carbon environmental protection and sustainable development, but also consider the other side of the pool equipment, lighting equipment, different requirements and functions. Engineering technology in the pool, except for its own professional theory, technology, equipment and practice, theory and practice of general water treatment technologies are swimming pool project has been widely used. For example: breakpoint chlorination, Blue's saturation coefficient, even skewed distribution of particle motion suspense eigenvalues, and so on. Physical properties: pure water is colorless, odorless, tasteless liquid, when the shallow water clear, blue-green water level deep. Chemical formula for water is H2O, the proportion of 1kg / l. Water is a compound composed of two hydrogen and one oxygen atom formed, OH bond in a hydrogen end positively charged, negatively charged oxygen side, because the hydrogen and oxygen electrical vary widely, this charge separation of the water with a very Good polarity, so only a highly polar substance will dissolve in water, like oil, a low polarity substance not compatible with water. High polarity of water, and salt in favor, is not conducive and lipid effects. Swimming pool, water park and spa leisure pool water used is far greater than the basic properties of water, it uses the other properties and effectiveness of water used to relax the body, the muscles, the spirit and mood, giving the console the mental and the physical and mental The health. 1. The nature of the health of water feature: buoyancy, resistance, solubility, penetration, diffusion capacity, emulsifying power, clean power, mobility and thermal compatibility. 2. the effect of water on the human body:. A thermal compatibility (temperature stimulation efficacy, effectiveness appease reconcile efficacy and water vapor moisture, weight-loss and cosmetic effect) b liquidity (injection pressure of the massage effect) c.. biochemistry (dissolution, penetration, diffusion capacity, emulsifying power, clean power) d. the role of water static pressure, buoyancy, resistance movement on the human body in the water. Pool pollution: a source of pool contamination:.. A human dirt, bacteria, viruses, urea and other b dander, hair cosmetics crumbs c d body secretions:.. Fat, sweat, nasal secretions e exotic mouth. things: dust, leaves, insects breeding pool f g fungi and algae balance tank, balanced water tank, filter media, the inner wall of the tube valve biofilm generated pollution. Two. When the water physical processing properties of the physical properties of the use of water and contaminants 1. All critical water is the use of the physical treatment of water is equal to the proportion of 1kg / l of the physical properties. 2. The key to all of the same loop filter is to use a different proportion of the physical properties of different pollutants. 3. The contaminants are more specific gravity of the specific gravity of water three cases: specific gravity less than water 1kg / l, the contaminants float to the surface of the pool; equal to the proportion of water 1kg / l, the contaminants can be suspended in water at any position ; specific gravity greater than water 1kg / l, the contaminants sink to the core issues of the bottom Swimming pool water physical treatment is different from the proportion of contaminants and water use gravity to separate intercept and filter these impurities. Loop filter: a loop filter should be used in the form of swimming pool water impurities are mainly brought in dirt swimmer, bacteria, cosmetics and body oils and sweat, as well as the outside world into the pool of debris, dust, leaves and fungi and algae breeding pool. Most of these impurities do not dissolve in water, due to the different specific gravity of a conventional float to the surface, some mixing in the water, some precipitate to the bottom. Impurities floating and sinking is a process and time intervals, floating and sinking speed affected by the proportion, but is also affected by the current. If the surface of the water and the bottom of the loop filter installed backwater system and let the water return system can put the proportion of water is less than 1kg / l and equal to 1kg / l impurities suction filtration system, while the bottom of the water return system specific gravity greater than 1kg / l and equal to 1kg / l impurities suction filtration system. Since this, just handle the surface and underwater impurities. If there is no water in the water return system for circulation, it is stagnant pool deck area; if the water does not circulate in the bottom of the filter, so the bottom is a dead zone. The treated water into the pool when the water supply, water distribution uniformity requirements, no dead, no short-circuiting. Two cell surface structures and facilities backwater system: skimming or overflow tank; backwater bottom structure and facilities systems: 1. skimming the bottom row is added to the bottom row, the bottom row of the overflow tank plus backwater way skimming Mo for the small pool, generally using skimming the pool when the water area ≦ 350 m, no water area of ??25 square meters-50 square meters of using a skimming device, and a pool of not less than two skimming devices, outdoor pool Under the limelight installed swimming season (north wall of the pool), 50% to 70% of water by skimming processing, different pollution can do special treatment, special circumstances 0-100% when skimming through processing has occur. When skimming is the scientific processing gravity of less than 1kg / l and equal to 1kg / l of impurities, while the bottom row of processing heavier than 1kg / l and equal to 1kg / l of impurities, such as the proportion of circulating manner different pollutants a. Overflow tank for physical handling large pool must be equipped with balanced (balance) water tank, 70% -100% of the flow of water through the overflow tank treatment, can also be overflow swimming pool surrounded by the two long sides of the overflow, also participated in the bottom row loop filter. The role of the sink overflow with skimming devices, handle gravity of less than 1kg / l and equal to 1kg / l of impurities, while the bottom row of processing heavier than 1kg / l and equal to 1kg / l of impurities, this cycle approach to the different specific gravities pollutants, it is science. Description: balanced tank not built and installed in the engine room, but with concrete construction in the pool, it can be easily treated sewage suction and dosing. When stationary, the pool water surface and equalization tank of water below ground in the same horizontal plane, the system work, circulating pump suction from the equalization tank, through the circulation, filtration, heating, sterilization systems for swimming pool water, balanced water tank reduce the water while swimming pool water rises, forming a water gap, so that you can return via the overflow tank, the specific gravity of less than impurity flow 1kg / l and equal to 1kg / l, and then you can make the bottom row simultaneously, the proportion is greater than 1kg / l and equal to the impurity flow 1kg / l of. It should be noted that, if the water from the bottom, so-called "short-circuiting" phenomenon can be ignored, because access to the pool from the outlet to the water, into the pool immediately after mixing with untreated water, mixed with dirty water The water discharge can not be called back in the end, "short-circuiting." Three swimming pools and other water supply mode cycle mode 1. Two Water Method: Water way to the wall and the bottom level of the water perpendicular to the water pool in two ways: the level of the water and the bottom wall perpendicular to the water, and both water supply and use independent way . Wall level water supply, construction, installation and operation is very convenient, it is one of the most common ways of water supply, but its drawback is that the heat distribution and chemical dosing uneven; the biggest advantage is that the water bottom vertical heat distribution and chemical adding more evenly, but it is construction, installation difficult. 2. Water Swimming scientific cycle mode there are two ways of water supply and the water bottom vertical wall level; backwater is two ways: skimming the bottom row is added to the backwater, plus overflow tank bottom row of backwater way. The water supply and return 2 × 2 way permutations, we can draw four kinds of round-robin fashion, the way these cycles are in use in other countries, they are: a best-robin fashion:. ① bottom vertical water supply, plus overflow tank bottom row backwater system. . b The most common way cycle: ② wall level water supply, skimming the bottom row is added to the backwater system. c-robin fashion available:. ③ bottom vertical water supply, skimming the bottom row is added to the backwater system. ④ wall level water supply, plus overflow tank bottom row backwater system. Conclusion: The Science of the cycle way is to ensure that all the different proportion of pollutants in the loop filtration system flows through the cycle, and then intercept, layered and removed. If the water does not circulate the pool, the water is stagnant zone; if there is no circulation bottom, the bottom is a dead zone. Surface and bottom dead zone dead zone both happen on our way downstream circulation, counter-cycle approach, which is the case in a foreign country to avoid. In the swimming pool filtration system, the balance tank, balance tank, filter media, the inner wall of the tube valve biofilm is no note of swimming pool water treatment an important part of treatment to use physical and chemical treatment processing. Downstream of the traditional round-robin fashion, counter-cycle ways and cycle way Francis did not consider such a biofilm treatment, and all three round-robin fashion influence and impede the balance tank to varying degrees, in the structure and construction or equalization tank processing. In the swimming pool engineering practice abroad, skimming the bottom row is added to the balance tank without backwater way, only when the overflow tank plus the bottom row of backwater balanced way (balanced) water tank, it can be convenient for physical treatment ( such as smoke pollution) and chemical treatment (dosing disinfectants, flocculants and chemical shock treatment).
