Municipal sewage treatment plant

Abstract

The application relates to a municipal sewage purification device. By hingedly connecting a filter plate in a treatment tank of the sewage treatment device, a first filter screen and a second filter screen are respectively connected at both ends of the filter plate, and the first filter screen is connected to the treatment The side wall of the tank, the second filter screen is connected to the opening of the collection container, so that during the movement of the filter plate, the first filter screen, the filter plate, the second filter screen and the collection container form a filter layer with a continuously changing shape, and the filter layer will process The tank is divided into upper and lower areas. When sewage is continuously discharged into the treatment tank and the shape of the filter layer is constantly changing, the filter layer is always located between the water inlet pipe and the drain pipe, which is conducive to improving the purification efficiency of the system and reducing the Probability of debris coming out of the drain.

Description

technical field [0001] The present application relates to the technical field of construction engineering, in particular to a municipal sewage treatment device. Background technique [0002] Municipal sewage purification system is a facility for discharging sewage after filtration and disinfection. In the related art, the municipal sewage purification system includes a holding tank, two ends of the holding tank are respectively connected with a water inlet pipe and a drain pipe, and a filter screen and a water inlet pipe are arranged in the holding tank. The nozzle is located above the filter screen, and the drain pipe nozzle is located below the filter screen. The sewage is discharged from the inlet pipe, and after being filtered by the filter screen, it is discharged from the drain pipe to complete the preliminary purification of sewage. [0003] In view of the above-mentioned related technologies, the inventor believes that the accumulated debris on the surface of the fil...

Problems solved by technology

[0003] In view of the related technologies mentioned above, the inventor believes that: the accumulated sundries on the surface of the filter net will affect the filtration efficiency of sewage. When the sundries need to be cleaned, the holding tank needs to stop entering the sewage before the sundries can be cleaned. Affects the efficiency of the purification system for the initial purification of sewage, so there is still room for improvement
