　　In cities, it is also known as a sewage treatment plant or sewage treatment plant. The ultraviolet disinfection module of the sewage treatment plant is located in the commonly known treatment station of the factory. When the effluent is discharged into the urban drainage pipeline, the treatment station is actually a pre-treatment facility. A wastewater treatment plant is a complex system composed of multiple unit processes, where the cost and efficiency of each unit process are interrelated and affect each other, ultimately determining the cost and efficiency of the entire system.

　　In cities, it is also known as a sewage treatment plant or sewage treatment plant. The commonly known treatment station located in the factory is actually a pre-treatment facility when the effluent is discharged into the urban drainage pipeline. The general goal of wastewater treatment is to remove suspended solids and improve oxygen consumption (i.e. stabilize organic matter), sometimes accompanied by disinfection and further treatment. The treatment of industrial wastewater focuses on the removal or transformation of oils, suspended solids, heavy metals, and organic compounds that hinder the operation of urban sewage plants or have high residues, as well as the adjustment of pH value

　　The process of Hainan sewage treatment plant ultraviolet disinfection module urban sewage treatment plant is determined according to the required treatment level and economic analysis. Usually divided into three levels: ① Level 1 processing. By using the precipitation method, the removal rates of suspended solids and five-day biochemical oxygen demand can generally reach around 60% and 30%, respectively. ② Secondary processing. By using the biological treatment method of water, the removal rate of suspended solids and five-day biochemical oxygen demand can generally reach about 90%. When using the high load rate activated sludge method, the removal rate of five-day biochemical oxygen demand is about 60%. ③ Third level processing. Further remove untreated substances from the secondary treatment. [1]

　　The main treatment structure of the primary sewage treatment plant is the sedimentation tank. Secondary sewage treatment plants are equipped with additional biological devices (such as aeration tanks, biofilters, biological turntables, or aerated biofilters) and post sedimentation tanks. Due to the presence and different functions of sedimentation tanks before and after, the former is often referred to as the primary sedimentation tank, while the latter is referred to as the secondary sedimentation tank. There are also auxiliary facilities and facilities for treating sludge from sedimentation tanks. Auxiliary facilities generally include grilles and sedimentation tanks (also known as impurity tanks). Remove lumps and cloth from the grille. The sand settling tank removes sediment to prevent it from accumulating in subsequent deep tanks and affecting operation. The facilities for treating sludge are generally digestion tanks and dewatering equipment (drying beds or dewatering machines). The buildings of wastewater treatment plants usually include pump rooms, laboratories, sludge dewatering rooms, repair shops, etc. Activated sludge treatment plants often have blower or air compressor rooms. In order to control operation, achieve economic dispatch, and improve management level, the ultraviolet disinfection module of Hainan sewage treatment plant has begun to adopt automation devices and electronic computer control, including: ① remote communication, telemetry, recording, and alarm of operating parameters such as water quality, water quantity, and power supply voltage; ② Automatic control and remote control of valve opening and closing and scheduling of water pump units; ③ Third level processing. The effluent quality of secondary treatment sometimes cannot meet the discharge requirements, so further treatment (or deep treatment) is carried out. The effluent from biological treatment methods is generally rich in ammonia, nitrogen, nitrate, and phosphate, and eutrophication often occurs when discharged into stagnant water bodies such as lakes and bays. At this time, facilities for nitrogen and phosphorus removal are often added. When the effluent is discharged into water bodies with extremely high water quality requirements or irrigated grasslands, sports fields, and recreational green spaces, and the water quality needs to be comprehensively improved, double-layer filter beds are often added. Some also use biological ponds and land treatment.

　　The location of the wastewater treatment plant should be coordinated with the outlet of the wastewater. The UV disinfection module of the wastewater treatment plant should consider the needs of the entire drainage system's phased construction and comply with urban land use planning. Wastewater treatment plants, especially those with sludge treatment and dewatering equipment, have a certain impact on the environmental quality of surrounding buildings and should have appropriate isolation green belts. The advanced computing technology has made the economic analysis of drainage system planning increasingly perfect, and the selection of sewage plant sites is often solved simultaneously with the planning of the entire system
