1、 Product Overview

For a long time, the water treatment processes in the swimming pool and bathing industry have mostly adopted chlorine disinfection technology. During operation, methods such as discharging sewage, adding new water, and increasing the number of cycles are used to purify and dilute raw water. However, the old processes lack efficient oxidation ability for various organic compounds, especially soluble organic compounds(20%～30%)As a result, organic matter adheres to the wall of the circulating pipe with the flow of raw water, forming a bacterial film fouling layer. The slow discharge of waste water exacerbates the high concentration chlorination disinfection byproduct water environment. This process comes at the cost of high energy consumption, low quality, overload filtration, and inability to regenerate and reuse. The transformation of old processes and the use of new technology processes have become urgent issues that need to be addressed in the industry.

2、 Theoretical basis

（1）TheUV/O3It is an advanced oxidation process that combines ozone and ultraviolet radiation. This method does not directly react with organic matter using ozone, but rather utilizes the active oxidant produced by the decomposition of ozone under ultraviolet light to oxidize organic matter.

（2）TheUV/O3The oxidation reaction is free radical type, which means that liquid phase ozone will decompose under ultraviolet radiation to form·OHˉFree radicals, derived from·OHˉFree radicals react with dissolved substances in water.

（3）The·OHˉThe reaction speed isO3Lawful100-1000Twice.

3、 System Description

UV/O3（AOPs）The system is a new type of water quality deep purification equipment,The system consists of three units: a precision filtration system, an ozone generator system, and a photocatalytic reaction device, designed to be fully enclosed and intelligent. The system operates through multiple processes including filtration, air-water mixing, control and regulation, storage, oxidation, and decomposition. The entire system has the advantages of high treatment efficiency, stable effluent quality, low operating costs, and small footprint. The system has now formed a water volume of30m3arrive2200m3of11A complete set of purification equipment of various models.

4、 System advantages

（2）It can effectively and widely oxidize and decompose humus and most organic matter in water, remove color, turbidity, odor, iron and manganese ions, sulfides, phenols, pesticides, etc.

（3）Significantly reduce the levels of chloramines, trihalomethanes, and free chlorine in the pool water.

（4）The water has high transparency and excellent water quality, which effectively solves the problem of removing human excrement.

（5）Reduce irritation to the skin and eyes, and ensure fresh indoor air.
（6）Strong adaptability, inPH5.6-9.8Water temperature0-37Within the temperature range, it can ensure the stability of large passenger flow water.
（7）Greatly reducing the management and operational difficulty of water treatment processes, while also having high safety.
（8）Can increase the filtration speed1/3Reduced consumption of backwash water50%Above, in order to reduce operating costs.
（9）The operating cost is lower than other biochemical and physicochemical combination processes, which can reduce the consumption of chemical reagents50%Or more.

（10）No additional civil engineering is required, installation only requires the configuration of inlet and outlet, power supply, and system to operate, without affecting the design process.
