Device for classifying and purifying domestic sewage

Abstract

The invention relates to the technical field of domestic sewage treatment, and discloses a domestic sewage classification and purification treatment device, which comprises a classification and purification device main body, a placement groove is formed in the inner wall of the left side of the classification and purification device main body, and an air bag is fixedly mounted on the inner wall ofthe placement groove; and a rotating rod is movably connected to the top of the supporting frame, and an extrusion block is fixedly mounted on the left side of the rotating rod. By opening a water stop valve, a rotating rod drives an extrusion block to extrude an air bag, so that the air bag blocks the rotating rod; when sewage contains soil, the rotating rod is stressed to rotate anticlockwise,and a metal baffle is driven to move downwards by virtue of a movable rod, so that the metal baffle blocks mutual attraction between two monopole magnets; then, the wooden plug in the water outlet ispulled back by the spring on the right side, so that sewage with soil is discharged into the diversion pipeline on the left side, and the effect of classifying the sewage is achieved.

Description

technical field [0001] The invention relates to the technical field of domestic sewage treatment, in particular to a device for classifying and purifying domestic sewage. Background technique [0002] With the acceleration of urbanization in our country, urban water shortages are becoming more and more serious; at the same time, the discharge of urban domestic sewage is increasing, and the increasingly serious water pollution reduces the use of water bodies, causing the contradiction between the supply and demand of water resources that are already scarce. sharper. The shortage of water resources has become a serious restrictive factor for the sustainable development of the national economy and society. [0003] At present, most households discharge vegetables and fruits directly into the sewer after washing vegetables and fruits with tap water or after washing dishes with detergent, which causes waste of water resources, or wastes water resources after use. Classify and d...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a device for classifying and purifying domestic sewage, which has the advantages of classifying different types of sewage and purifying the classified water in different ways and then storing them separately, solving the problem of Tap water is discharged directly into the sewer after washing vegetables and fruits or dishes with detergent, which causes waste of water resources, and the used water resources are directly filtered and purified without classification and then reused. , leading to the problem that polluted water sources cannot be completely purified
