Embodiment Construction

[0036] The present invention will be further described in detail below in conjunction with examples, but the embodiments of the present invention are not limited thereto.

[0037] Such as figure 1 as shown, figure 1 The domestic sewage treatment system of an embodiment is shown, and the domestic sewage treatment system comprises a sump 1, an aerobic processor 2, a biochemical reactor 3 and a sludge drying tank 4, and the collected water is collected by setting a water pump 5 and a sewage pipe. The sump 1 is connected to the aerobic processor 2; first, the domestic sewage enters the sump 1, and the sump 1 stores the domestic sewage, and then the domestic sewage in the sump 1 is pumped to the aerobic treatment by the water pump 5 Carry out aerobic pretreatment in the aerobic processor 2, aerate it through the aeration fan in the aerobic processor 2, and the sewage in the system sump 1 of the present embodiment directly enters the aerobic processor 2, omitting the prior art cle...

Abstract

The invention discloses a domestic sewage treatment system and method. The domestic sewage treatment system comprises a sump, a facultative treatment device, a biochemical reactor and a sludge drying tank, the sump is used for storing domestic sewage; the facultative treatment device is connected with the water collecting pit through a pipeline, the facultative treatment device comprises three layers of water treatment structures, the upper layer is a residue and oil separation layer and is used for removing oil residues and oil stains in domestic sewage, and the middle layer is an aerobic biological filler layer and is used for carrying out aerobic biological treatment; the lower layer is an anaerobic biological filler layer for anaerobic biological treatment; the biochemical reactor is used for intercepting particulate matters and carrying out an aerobic biochemical reaction; and the sludge drying tank is used for collecting sludge in the facultative treatment device. The domestic sewage treatment effect and quality are improved, and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of domestic sewage treatment, in particular to a domestic sewage treatment system and method for rural or urban areas. Background technique [0002] As far as domestic sewage treatment in rural areas and towns is concerned, the pollutants contained in domestic sewage are mainly organic matter (such as protein, carbohydrates, fat, urea, ammonia nitrogen, etc.) and a large number of pathogenic microorganisms (such as parasite eggs and intestinal infectious viruses Wait). The organic matter present in domestic sewage is extremely unstable and easily rots to produce stench. Bacteria and pathogens reproduce in large numbers using organic matter in domestic sewage as nutrients, which can lead to the spread of infectious diseases. Therefore, domestic sewage must be treated before discharge. Among the existing treatment methods, for example, a Chinese patent application (application publication number is CN 11342...
