Abstract

The invention relates to the technical field of non-point source pollution control and treatment, in particular to a collection and retreatment system for agricultural non-point source polluted farmland drainage. Existing system treated water has a lot of impurities, cannot be applied to farmland irrigation, cannot realize water recycling and causes waste. The collection and retreatment system for agricultural non-point source polluted farmland drainage provided by the invention includes a water collection unit and a water treatment unit, the water collection unit comprises a water gathering grit pool and a hydrolysis acidification pool that are interconnected through a first water outlet pipe, the water treatment unit includes an anaerobic sedimentation pool and a soil percolating filter that are interconnected through a second water outlet pipe, and the anaerobic sedimentation pool is communicated with the hydrolysis acidification pool through an effluent hole. Therefore, the water gathering grit pool can intercept runoff sediment and suspended matters, the soil percolating filter treats high concentration farmland drainage, and the treated farmland drainage can be reused for farmland irrigation, thus realizing the water recycling.

Description

technical field [0001] The application relates to the technical field of non-point source pollution control and treatment, in particular to a collection and reprocessing system for agricultural non-point source polluted farmland drainage. Background technique [0002] Agricultural planting and agricultural production provide the country and the people with food and industrial raw materials. They are not only an important pillar of national food, but also the basis for national economic development and social stability. In the industrial structure of agriculture, forestry, animal husbandry and fishery, agriculture occupies the largest proportion. The demand for food is large, and the demand for agricultural water is also increasing. Traditional immersion irrigation technology not only wastes water resources, but also easily causes land salinization, and will bring fine particles or water-soluble pollutants to groundwater or surface water in large areas. In the past 30 years...
