Rural sewage recycling treatment system

Abstract

The invention relates to a rural sewage recycling treatment system. The system comprises an ecological treatment tank, and a grid treatment tank, a preheating tank and a denitrification filter tank which are connected in sequence. A solar heating device is arranged at the bottom of the preheating tank, one end of the solar heating device extends out of the preheating tank, and the bottom of the preheating tank is communicated with the denitrification filter tank through a water pumping pipeline. The ecological treatment tank sequentially comprises an ecological plant layer, a soil layer, a contact adsorption filler layer and a water outlet layer from top to bottom, and effluent of the denitrification filter tank flows into the ecological plant layer of the ecological treatment tank. The treated effluent is discharged to a river body and a pond and can be reused for front-end domestic water, irrigation and the like.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a rural sewage resource treatment system. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] As the country's economic development drives the improvement of rural living standards, rural areas are facing increasing pressure from environmental pollution. It is mainly reflected in three aspects: first, the increase in water consumption brought about by the improvement of the rural level; second, the reduction of rural green vegetation and the impact of soil erosion; third, a large number of pollution indicators are discharged into the water body together with t...

Problems solved by technology

This part of polluted wastewater not only directly leads to the deterioration of the rural ecological environment, but also pollutes rivers, ponds, and groundwater. It not only poses a threat to the safety of drinking water for nearby residents, but also leads to a reduction in the production of food crops.

In recent years, my country's treatment of rural sewage has also been continuously improved, but it is also facing the following problems: 1) Due to the characteristics of decentralization and economy in rural areas, the infrastructure investment and operating costs are relatively large; 2) Professional Lack of technical personnel makes it difficult to ensure the stable operation of the process; 3) Many technologies are in the demonstration research stage, and there are few demonstration projects for rural domestic sewage treatment
