Shanneng Zhao Shunying Photovoltaic Power Generation and Domestic Sewage Treatment

The products from our company used in this domestic sewage treatment include quartz sand filters and ultraviolet sterilizers. Quartz sand filters, also known as shallow media filters, are a branch of mechanical filters. The media inside is quartz sand, which can trap sediment, colloids, suspended solids, and other particles, effectively reducing the turbidity of the sewage! Besides quartz sand, the media can also include activated carbon, anthracite, garnet, etc., depending on the desired water treatment effect. Ultraviolet sterilizers are commonly used equipment for sterilization and disinfection in domestic sewage. According to different water treatment needs, ultraviolet lamps with matching power are selected. The ultraviolet light irradiation effectively alters the DNA structure of microorganisms, causing bacterial death, thereby achieving sterilization.

 Dirty water enters from the filter inlet, first passing through the coarse filter screen to remove larger particles, then reaching the fine filter screen. During filtration, the fine filter screen gradually accumulates dirt and impurities from the water, forming a filter impurity layer. Because the impurity layer accumulates on the inside of the fine filter screen, a pressure difference forms on the inside and outside of the fine filter screen. When the pressure difference of the self-cleaning filter reaches the preset value, a switch signal is sent to the control box PLC system to start a cleaning cycle. Cleaning process: The cleaning mechanism of the fully automatic negative pressure suction filter is a stainless steel spiral up-and-down moving suction scanner. It is hollow in structure, with several suction nozzles vertically distributed at certain distances along its axis. The inside of the suction scanner communicates with the 3” drain valve. When the drain valve opens, the pressure difference between the internal water pressure of the filter and the external atmospheric pressure generates strong suction at each suction nozzle. At each suction nozzle, water flows rapidly from outside to inside in reverse, washing impurities attached to the inner wall of the filter screen into the suction nozzle, through the hollow shaft of the suction scanner, then discharged through the drain valve, completing the cleaning process which takes about 30-60 seconds. At this time, the pressure difference returns to normal, the cleaning process ends, and filtration resumes. During cleaning, the system continues to flow.
