Abstract

The invention is a multi-layer rotary drum type photocatalytic purification pool suitable for farmland drainage ditches. The cage is fixed parallel to the support seat through the rotating shaft, the photocatalytic ceramic particles are placed in the rotating purification cage, the ultraviolet lamp is fixed between the rotating purification cages, the top of the support seat is 10~20cm higher than the top of the purification pool, and the rotating purification cage is connected to synchronous drive device. The invention has the advantages of simple structure, high purification efficiency, maintenance-free and the like, and can be used for treating heavily polluted farmland drainage.

Description

technical field [0001] The invention relates to a multi-layer drum-type photocatalytic purification pool suitable for farmland drainage ditches, and belongs to the technical field of farmland non-point source control. Background technique [0002] With the rapid development of world industrialization and the further improvement of agricultural intensification, agricultural non-point source pollution has become one of the important sources of global water pollution, especially nitrogen and phosphorus pollution is the most serious, agricultural non-point source pollution has caused groundwater pollution, nitric acid The excess of salt and the enrichment of nitrogen and phosphorus in surface water lead to the overall deterioration of water quality and eutrophication in rivers and lakes, causing a series of global water environment governance problems such as wetland degradation and red tide. Controlling and reducing non-point source pollution has become a major problem in the f...
