Embodiment Construction

[0024] 1. Domestic sewage and pig-raising wastewater enter the domestic biogas tank for treatment, and the treated sewage enters the farmland and vegetable fields. The sewage from the farmland and vegetable fields flows into aerobic fish ponds and artificial wetlands respectively through field ditches or designed ditches. The sewage from aerobic fish ponds also Access to constructed wetlands.

[0025] 2 The sewage from the surface runoff enters the plant buffer zone, and the sewage flowing out of the plant buffer zone enters the aerobic fish pond and the constructed wetland respectively through the designed ditches, and the sewage from the aerobic fish pond can also enter the constructed wetland.

[0026] 3. The surface water enters the aerobic fish pond and the artificial wetland respectively through the designed ditches after replenishing water from the sewage of the canal, and the sewage of the aerobic fish pond enters the artificial wetland.

[0027] 4. Wastewater from agr...

Abstract

The present invention provides a technique for processing rural area non-point source pollution by controlling source (centralizing)-intercepting pollution (dredging)-reclaiming, comprising centralizing, intercepting and dredging the waste water to an artificial wetland by using a plant buffer zone, a pond and a field channel, centralizing, dredging and intercepting the waste water by using the plant buffer zone, a methane tank, a natural channel, a field pit, a fishpond, the artificial wetland and organism thereof, converting the domestic waste water and the pig raising waste water into domestic methane and fertilizer by methane tank technique or converting the pollutant into the feed of the fish, and reclaiming the waste by planting commercial crop, such as reed and the like, in the artificial wetland. The technique has low investment cost and running cost and is easy to perform and manage.

Description

technical field [0001] The invention relates to the technical field of rural pollution, especially rural non-point source pollution treatment. Background technique [0002] Rural non-point source pollution is an important factor of Poyang Lake water pollution. A large amount of farmland is concentrated in the Poyang Lake area. The irrational application of chemical fertilizers in agricultural production causes a large amount of nitrogen and phosphorus to be absorbed by crops and leached through rainfall runoff, which eventually causes nitrogen and phosphorus pollution to the water body. At present, the harm caused by rural non-point source pollution in the Poyang Lake Basin has attracted the attention of the government and environmental protection research institutes. Different treatment processes have been developed successively, and various rural non-point source pollution treatment projects have been established. [0003] In view of the characteristics of non-point sourc...
