The working principle of swimming pool water treatment equipment involves several key processes to ensure the water remains clean and safe for users. 1. **Filtration**: Water from the pool is drawn into the filtration system, where it passes through filters that remove debris, dirt, and other particles. This can include sand filters, cartridge filters, or diatomaceous earth filters. 2. **Disinfection**: After filtration, the water is treated with disinfectants, such as chlorine or bromine, to kill bacteria, viruses, and other harmful microorganisms. Some systems may also use UV light or ozone for disinfection. 3. **pH Balance**: The pH level of the water is monitored and adjusted to maintain a safe and comfortable swimming environment. Proper pH levels help ensure the effectiveness of disinfectants and prevent skin and eye irritation. 4. **Circulation**: The treated water is then circulated back into the pool, ensuring that all areas of the pool receive clean water. This circulation process is essential for maintaining water quality. 5. **Chemical Monitoring**: Regular testing of water chemistry is performed to ensure that the levels of chlorine, pH, alkalinity, and other chemicals are within safe ranges. Automated systems may be used for continuous monitoring and adjustment. Overall, the combination of filtration, disinfection, pH balancing, and circulation works together to keep swimming pool water clean, clear, and safe for swimmers.

The water from the swimming pool is collected through an overflow drainage system and gathered into a balance tank, where it enters the circulation water pipeline along with supplementary water. Driven by the circulation pump, it flows through a hair collector to filter out hair and larger particles; then it enters the automatic coagulant dosing system. This system uses a precision metering pump to accurately add aluminum sulfate solution (10% Al2(SO4)3) in proportion to the circulation water pipeline, causing the colloidal substances in the circulation water to coagulate into larger flocculent particles, which are then thoroughly filtered by a quartz sand filter. The pH automatic adjustment system compares the measurement signal from the pH sensor with the set value. After the microcomputer performs PLD calculations on the difference, it issues control commands, and the precision metering pump injects dilute hydrochloric acid (10% HCl) into the circulation water to maintain the acidity and alkalinity of the swimming pool water within the national standards (pH=7.0-7.8) as per the "Swimming Pool Water Quality Standards" (CJ244—2007). Finally, the disinfectant automatic adjustment system uses residual chlorine sensors or redox potential sensors to measure the disinfection and sterilization capacity of the pool, and the controller accurately controls the metering pump to add sodium hypochlorite disinfectant (5% NaClO) to keep the residual chlorine concentration in the swimming pool water within the national standards (0.3-0.6 ppm), effectively killing various bacteria and completing purification and disinfection.
