Household sewage treatment equipment

Abstract

The invention relates to a sewage treatment technology in environment engineering, in particular to household sewage treatment equipment. The interior of a stainless steel box body is divided into a first septic tank, a second septic tank, an anaerobic area, an anoxic area, an aerobic area, a precipitation area and a disinfection area by partitions from the front end to the rear end of the stainless steel box body; the anaerobic area, the anoxic area and the aerobic area are filled with suspension fillings; a first aeration barrel and a first aerator are vertically and fixedly arranged in theanoxic area; a second aeration barrel and a second aerator are vertically and fixedly arranged in the aerobic area; an air supply port of an air pump is communicated with an air injection pipe througha second air supply pipe via a part, close to the bottom in the precipitation area, of a rear pipe section of the air injection pipe and further communicated with the first septic tank and the precipitation area through the air injection pipe; a hydraulic solid-liquid phase separator is vertically and fixedly arranged in the middle in the precipitation area in an overhung manner; the aerobic areais communicated with a water inlet pipe of the hydraulic solid-liquid phase separator; and a water outlet pipe of the hydraulic solid-liquid phase separator is communicated with the disinfection area. The equipment is particularly applicable to countryside household treatment of domestic sewage.

Description

technical field [0001] The invention relates to environmental engineering sewage treatment technology, which is suitable for scattered domestic sewage treatment in rural areas, in particular household sewage treatment equipment. Background technique [0002] With the development of rural urbanization, the problem of environmental pollution caused by decentralized domestic sewage is becoming more and more serious. In the urban-rural integration zone and remote areas in the northwest, there are many areas that cannot be reached by urban sewage pipe networks, and the domestic sewage generated is generally directly discharged into In the natural environment, the problem of environmental pollution in some living areas has become increasingly serious. Due to the vast land and sparse population in Northwest China, the investment in large-scale sewage treatment equipment is large and the returns are small, which is not suitable for the needs of urban development in Northwest China. ...
