A filter device for sewage treatment

Abstract

The invention belongs to the technical field of sewage treatment, and particularly relates to a sludge treatment and filter device. The sludge treatment and filter device comprises a filter unit I, afilter unit II, a bottom plate, a telescopic mechanism and a cleaning unit, wherein the filter unit I and the filter unit II are alternately arranged on the side edge of the upper surface of the bottom plate; the upper end of the filter unit II is mounted on the lower surface of a cover plate through the telescopic mechanism; the filter unit I comprises four filter devices I which are uniformly distributed above the bottom plate in a periphery layout form; each filter device I comprises a filter screen I and concave blocking heads; the left end and the right end of each filter screen I are separately connected with the corresponding concave blocking heads; each filter device II comprises a filter screen II and convex blocking heads; and the left end and the right end of each filter screenII are connected with the corresponding convex blocking heads. The sludge treatment and filter device is mainly mounted in a small sewage treatment device used by a rural resident population, can filter sewage, can exhaust residues, and can automatically clean.

Description

Technical field[0001]The invention belongs to the technical field of sewage treatment, and specifically is a sewage treatment filter device.Background technique[0002]Although our country vigorously advocates improving the environment, polluted rivers and soil can be seen everywhere in our country, and domestic sewage is increasingly polluting the environment. In urban areas, there are generally special sewage treatment plants that treat domestic sewage at the same time. However, in the vast rural areas of our country, domestic sewage is discharged anywhere, at will and at any time, and there are no binding laws and regulations or restrictions. With the improvement of people’s living standards, rural residents have higher and higher environmental requirements. However, my country’s rural areas are relatively wide and residents’ lives are relatively scattered. If rural domestic sewage is collected and treated in a unified manner, a large area of ​​sewage must be laid. The pipeline is ...

Problems solved by technology

Although this technical solution can realize centrifugal filtration of sewage, this technical solution can only physically filter sewage, and it is not easy to be installed in other sewage treatment systems, such as sewage treatment equipment that requires physical filtration, chemical decomposition and biodegradation. A physical filtering device is used, and this technical solution cannot be effectively used in conjunction with sewage treatment equipment. At the same time, there is no cleaning device in this invention, and the residues adhered in the filter container cannot be automatically cleaned, so that the use of this invention is restricted. limit
