Abstract

The invention discloses a household processing system for sewage and belongs to the field of sewage processing. The household processing system is composed of a sedimentation oil-separation pool, a filler pool, a storage-water lifting pool, an automatic reoxygenation biological pool and a constructed wetland bed which are in successive connection; the automatic reoxygenation biological pool is inside provided with a filler layer, the pool wall of the automatic reoxygenation biological pool is provided with a reoxygenation pipe and a vent, and the bottom of the automatic reoxygenation biological pool is provided with an aeration pipe; the automatic reoxygenation biological pool is connected with the constructed wetland bed via a perforated water-discharge pipe; and the constructed wetland bed is connected with a reuse water storage pool or is connected with a local surface water body. The household processing system for sewage solves the technological problems that a conventional small-size sewage processing technology cannot enable sewage processing to reach the standard and is relatively large in energy consumption, and the sewage household processing system provided for people is simple in technology, convenient to operate and low in energy consumption, and processed sewage reaches the standard and can be discharged into the water storage pool for agricultural use.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a household sewage treatment system. Background technique [0002] Rural areas located in hilly and mountainous areas, where farmers live scattered, are not suitable for building centralized sewage treatment stations, and are suitable for building small-scale sewage treatment facilities for individual households; in addition, farmhouses, gas stations, and other catering, entertainment, and service facilities located in the suburbs of cities are often set up separately , the generated domestic sewage needs to be treated separately. However, the existing small-scale sewage treatment process has the problems of substandard wastewater treatment and high energy consumption. Contents of the invention [0003] The purpose of the present invention is to solve the technical problems of substandard wastewater treatment and high energy consumption in the existing small-scale s...
