Problems solved by technology

[0004] The purpose of the present invention is to provide a rural decentralized sewage ecological treatment process to solve the problem of rural household domestic wastewater including kitchen water, toilet water, and washing water. Source pollution load further affects crop growth and river water quality. In many small and medium-sized cities and rural areas there are no sewage collection pipes, and untreated domestic drainage has become one of the important sources of pollution. Due to high construction and operating costs, these areas do not It is suitable for the introduction of centralized sewage treatment system, but requires low-cost, high-efficiency, decentralized sewage treatment technology

Embodiment example

[0040] Inject the domestic sewage generated in the countryside into the sewage collection sedimentation tank, put flocculant into the sewage collection sedimentation tank, let it stand for 5-6 hours, wait for the sludge in the sewage to settle to the bottom of the sewage collection sedimentation tank, open the sewage collection sedimentation tank The gate, the sewage from which the sludge has been removed flows into the diversion channel, and the workers start the sludge conveying pump to pump out the sludge settled at the bottom of the sewage collection sedimentation tank through the sludge pumping pipe, and process the pumped out sludge;

[0041] When the sewage flows through the stepped diversion channel, the stepped diversion channel can increase the distance of the sewage and increase the contact area between the sewage and the air. effect of aeration;

[0042] The sewage flowing along the diversion channel will enter the constructed wetland, and the sewage will pass thro...

Abstract

The invention relates to the technical field of sewage ecological treatment processes, in particular to a rural distributed sewage ecological treatment process, which comprises a sewage collection sedimentation tank, a flow guide channel, an artificial wetland, an ecological fishpond and a water storage tank, and is characterized in that the artificial wetland is connected with the water storage tank through a flow guide pipe; the constructed wetland is composed of a pool body, a base layer, a first aquatic plant and a second aquatic plant, the rural distributed sewage ecological treatment process effectively solves the problems that rural domestic wastewater comprises kitchen water, toilet water, washing water and the like, if rural domestic wastewater is not properly treated, the non-point source pollution load of agricultural land can be increased, no sewage collection pipeline exists in many small and medium-sized cities and rural areas, untreated domestic drainage becomes one of important pollution sources, and due to high construction and operation cost, the areas are not suitable for being introduced into a centralized sewage treatment system, and a low-cost, high-efficiencyand distributed sewage treatment technology is needed.

Description

technical field [0001] The invention relates to the technical field of sewage ecological treatment process, in particular to a rural decentralized sewage ecological treatment process. Background technique [0002] Rural domestic wastewater includes kitchen water, toilet water, washing water, etc. If rural domestic drainage is not properly treated, it will increase the non-point source pollution load of agricultural land and further affect crop growth and river water quality. In many small and medium-sized cities and rural areas There is no sewage collection pipeline in the area, and untreated domestic drainage has become one of the important sources of pollution. Due to the high construction and operating costs, these areas are not suitable for the introduction of centralized sewage treatment systems, but need low-cost, high-efficiency, decentralized type of sewage treatment technology. [0003] In summary, the present invention solves the existing problems by designing a r...
