Embodiment 1

[0039] Now, a decentralized method for separation, treatment and resource utilization of domestic sewage of the present invention is applied to a farmer in Tandang Village, Xinzhuang Town, Changshu City, Jiangsu Province. There are four members of the farmer. The new house is a three-story building, and each floor is equipped with a traditional flush toilet. There are flower beds and fish ponds in front of the house, and gardens and vegetable fields behind the house. All sewage produced goes straight to the ditch next to the sewer without any treatment.

[0040] First, the farmer's toilet was replaced with a vacuum water-saving toilet, and a black water collection pipeline was laid. Existing sewage pipes are used as grey water collection lines. In this way, black water and grey water can be separated and collected. Secondly, the domestic sewage separated from the source enters the black water and gray water treatment systems for treatment respectively. The treated black wa...

Embodiment 2

[0047] The method for separating, treating and reusing sources of distributed domestic sewage of the present invention is applied to a farmer in Dongqing Village, Yushan Town, Changshu City, Jiangsu Province. The family of six is ​​a two-story building built many years ago, without sanitary facilities such as flush toilets and squatting pans and pipe networks. There are vegetable fields and septic tanks behind the house. Firstly, the sanitation facilities of the farmer were improved, vacuum water-saving toilets were installed on the first and second floors of the farmer, and black water and grey water pipe networks were laid at the same time. Black water is collected through vacuum water-saving toilets, drained into a converted septic tank, and then applied to vegetable fields. The grey water such as kitchen water and bathing water is collected through the grey water pipe network and entered into the grey water treatment system for treatment and reuse.

Abstract

The invention discloses a distributed domestic sewage source separation treatment and reclamation method, relating to the technology of environmental protection, wherein the method uses a black and gray water separation and collecting system, a black and gray water processing system, and a black and gray water reclamation use system. The technology of the black water system comprises the followings: black water, vacuum water-saving toilet, vacuum pump, vacuum tank, black water collecting box, fermentation, and reclamation; and the technology of the gray water system comprises the followings: gray water, pretreatment, land processing system, water discharge, and reuse. The method uses distributed domestic sewage to separate, process and recycle at the source, which can save water, solves the problem of random discharge of distributed domestic sewage in the town, improves the environment, and realizes the recycling use of domestic sewage; and the method has the advantages of low building cost, simple and convenient construction, small occupied area, low operation cost and simple maintenance, and has strong practical and popularization values.

Description

technical field [0001] The invention relates to the technical field of environmental protection, and is a method for separation, treatment and resource utilization of the source of distributed domestic sewage, which controls water pollution, can separate the source, treat and recycle the distributed domestic sewage, can effectively save water consumption, and make The treated domestic sewage meets the reuse standard. Background technique [0002] For many years, the focus of our country's environmental protection work has always been the problem of environmental pollution in cities, rural areas and scattered residential areas, which are currently blind spots or dead spots in the field of pollution control. In rural my country, the sewage collection pipe network is not perfect and the sewage treatment facilities are not perfect. The fecal sewage and other domestic water are not properly treated, and they are discharged or infiltrated into the ground at will, polluting the env...
