A sewage treatment filter

Abstract

The invention relates to the technical field of sewage treatment, in particular to a filter for sewage treatment, which includes a fixed base, a support rod and a filter device. The upper end of the fixed base is symmetrically installed with support rods on the front, rear and both sides, and the upper ends of the support rods are connected to each other. There is a filter device; the present invention can solve the problem that solid waste is easy to accumulate on the filter device after filtering domestic sewage for a period of time, and it is difficult to clean up in time, and the structure of the traditional domestic sewage filter device is relatively simple, usually it is to directly pass the domestic sewage through The filtering device can not separate and recycle garbage of different volumes and other problems; the present invention designs a filter that uses centrifugal force to filter sewage, which can be cleaned in time while filtering, ensuring the filtering efficiency of the filtering device , and classify the cleaned garbage and discharge it separately, which reduces the burden on the filter device.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment filter. Background technique [0002] Sewage refers to the polluted discharge water from life and production. According to the source of sewage, sewage can be divided into four categories: industrial wastewater, domestic sewage, commercial sewage and surface runoff, while domestic sewage is the most common kind of daily life of residents. Wastewater discharged in life, domestic sewage mainly comes from residential buildings and public buildings, such as residences, institutions, schools, public places and industrial enterprise toilets, etc.; the pollutants contained in domestic sewage are mainly organic matter and a large number of pathogenic microorganisms, which are easy to corrode and Odor is produced, and bacteria and pathogens multiply by using organic matter in domestic sewage as nutrition, which can lead to the spread of infectious diseases. The...

AI Technical Summary

Problems solved by technology

[0003] At present, there are usually the following defects in the treatment of domestic sewage: 1. When filtering domestic sewage, filter devices such as filter screens are usually used to filter directly. After a period of filtration, solid waste is easy to accumulate on the filter device and it is difficult to clean up in time , will reduce the filtering effect of the filter device during the working process; 2. The structure of the traditional domestic sewage filter device is relatively simple, usually the domestic sewage is directly filtered through the filter device, and the domestic sewage contains garbage of various sizes , direct filtration will increase the burden on the filtration equipment and cannot separate and recycle waste of different volumes
