Municipal sewage integrated treatment device

Abstract

The invention relates to a municipal sewage integrated treatment device which comprises a filter tank, an oil removal tank and a U-shaped pipe connected between the filter tank and the oil removal tank, a grating plate is arranged in the filter tank, a cleaning assembly used for cleaning the grating plate is arranged in the filter tank, and a flushing assembly is arranged in the filter tank. The flushing assembly comprises a sliding block slidably connected into the filtering tank, a water pipe penetrating through the sliding block and a nozzle connected to the side, facing the grating plate, of the water pipe, and the end, away from the nozzle, of the water pipe penetrates through the side wall of the filtering tank and communicates with an external water source. The sewage integrated treatment device has the effect of reducing the possibility that secondary pollution is caused in the integrated sewage treatment process, so that the treatment period and the treatment effect of the sewage are influenced.

Description

technical field [0001] The present application relates to the field of municipal sewage treatment, in particular to an integrated municipal sewage treatment device. Background technique [0002] That is, domestic sewage, industrial wastewater and runoff sewage within urban areas. Generally, it is collected by urban pipes and canals and should be treated by urban sewage treatment plants before being discharged into water bodies. In addition to containing a large amount of organic matter, germs and viruses in urban sewage, due to the high development of industry, the volume of industrial wastewater (accounting for about 60-80% of the total urban sewage), the water quality is becoming more and more complex and the pollution of runoff sewage is becoming more and more serious, making urban sewage Contains various types and degrees of various toxic and harmful pollutants. [0003] The treatment of urban sewage in our country generally needs to be collected first, and then go thr...

Problems solved by technology

[0005] In view of the above-mentioned related technologies, the inventor believes that after the sewage is filtered for large and small particles of debris in the filter tank, when the filter tank is opened to remove impurities from the filter tank, due to the limitation of the range of the filter tank, it is difficult to filter the coarse particles. The surface of the grille and the fine grille is completely clean, and the garbage is easy to get stuck in the grille, which will cause the garbage to accumulate and rot in the filter tank, causing secondary pollution to the sewage, and when cleaning, some small particles may come out from the gaps in the grille. If it falls into the U-shaped pipe and opens the drain valve, the particles falling into the U-shaped pipe may remain on the wall of the U-shaped pipe, which will also cause secondary pollution to the sewage
