Embodiment 1
[0039] Now, a decentralized domestic sewage source separation treatment and recycling method 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's family. 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 the sewage generated enters the sewer without any treatment and is directly discharged into the ditch next to it.
[0040] First, replace the flush toilet of the farmer with a vacuum water-saving toilet, and lay black water collection pipelines. Existing sewer pipes were used as gray water collection lines. In this way, black water and gray water can be separated and collected. Secondly, the domestic sewage separated at the source enters the black water and gray water treatment systems for treatment respective...

[0047] A decentralized domestic sewage source separation treatment and recycling method of the present invention is applied to a farmer in Dongqing Village, Yushan Town, Changshu City, Jiangsu Province. There are six members of the farmer's family. It is a two-story building built many years ago, without sanitary facilities such as flush toilets and squatting toilets, and pipe networks. There is a vegetable field and a septic tank behind the house. First, improve the sanitation facilities of the farmer, install vacuum water-saving toilets on the first and second floors of the farmer, and lay black water pipe network and gray water pipe network at the same time. Black water is collected through vacuum water-saving toilets, discharged into a modified septic tank, and then applied to vegetable fields. Gray water such as kitchen water and bath water is collected through the gray water pipe network and enters the gray 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 field of environmental protection technology, and is a method for separating the source of distributed domestic sewage and recycling it, which can control water pollution and can separate, treat and recycle the distributed domestic sewage at the source, which can effectively save water consumption and make the The treated domestic sewage reaches the reuse standard. Background technique [0002] Over the years, the focus of my country's environmental protection work has always been on cities, and the environmental pollution in rural areas and scattered residential areas is currently a blind spot or dead end in the field of pollution control. In my country's rural areas, there are generally unsound sewage collection pipe networks and imperfect sewage treatment facilities. Without proper treatment, fecal sewage and other domestic water are discharged or infiltrated into the ground at will, polluting the environment; cause harm...
