Problems solved by technology

[0003] Using ultraviolet photocatalysis, although the volume can be greatly reduced, its cost is high. The main reason is that its processing efficiency is low, and the ultraviolet lamp needs to be cleaned regularly, resulting in high maintenance costs.

Abstract

The invention discloses a reversing water valve and its sewage treatment system based on photocatalysis. The sewage treatment system includes: a reversing water valve, which is used to connect the sewage in series to the drainage pipe, and choose one to connect the sewage with the sedimentation tank, The next reversing water valve is connected; the sedimentation tank is used to store sewage, and it is allowed to stand and settle; the stop valve is used to control the on-off of the pipeline between the supernatant of the sedimentation tank and the inlet of the first water pump; the water level gauge, It is used to detect the water level in the sedimentation tank; the outlet of the first water pump is connected with the inlet of the filter, so as to pump the supernatant after sedimentation in the sedimentation tank to the filter; the filter is used to filter suspended solids or large particles of impurities in the water ; The water catalyst is used to irradiate sewage with ultraviolet light, so that the organic matter in the sewage is decomposed into inorganic matter.

Description

technical field [0001] The invention relates to sewage treatment technology, in particular to a reversing water valve and a sewage treatment system based on photocatalysis. Background technique [0002] For some wastewater containing a large amount of organic matter (VOC), aerobic fermentation and anaerobic fermentation are mainly used for treatment at present, but this method will take up a large space, which is obviously not suitable for factories with insufficient space. With the strengthening of environmental protection laws and the deepening of environmental protection concepts, organic wastewater exceeding the standard cannot be discharged directly. For enterprises that can establish wastewater treatment systems, they basically treat wastewater by themselves. For enterprises with insufficient space, their wastewater often needs to be transported to a professional wastewater treatment station for treatment. This will obviously cause high processing costs, cause relati...
