Domestic sewage treatment device

Abstract

The invention belongs to sewage treatment devices, and relates to a domestic sewage treatment device. The domestic sewage treatment device is mainly characterized in that a horizontal tank body is internally and separately provided with a sedimentation aging cavity, a scum separation net, a grit filtering cavity, an active adsorption cavity and a bio-enzyme catalysis cavity, wherein the sedimentation aging cavity is provided with dredging pipes. According to the domestic sewage treatment device disclosed by the invention, septic tanks of the existing living area are greatly modified, and domestic sewage is comprehensively treated by multiple multi-cavity continuous manners; and the domestic sewage treatment device disclosed by the invention has the remarkable advantages that the treatment cost is low, the purification effect is good, the living environment is improved, the treated domestic sewage reaches the national comprehensive drainage standard, a problem that the domestic sewage pollutes underground water and rivers is effectively solved, the blockage of underground pipes is avoided, the loads of sewage treatment plants are reduced, dredging and cavity cleaning operations are convenient, the service life is prolonged and the like.

Description

technical field [0001] The invention belongs to the field of environmental protection facilities and relates to a domestic sewage treatment device. Background technique [0002] In traditional domestic sewage treatment facilities, septic tanks are often installed in residential areas to connect with residential sewage drainage pipes, and then discharged after standing and settling in primary or tertiary small pools. If it is discharged to the ground, it will pollute the surface and groundwater; if it is discharged to the river, it will cause secondary pollution such as eutrophication of the river and cause a large number of aquatic organisms to die; if it is collected in the sewage treatment plant, or the underground pipe network is blocked, it will increase The load of sewage treatment plants. Contents of the invention [0003] The applicant has been engaged in the production and operation of water treatment equipment for many years, and found that the traditional domest...
