Aquatic plant platform structure for sewage treatment of rivers and lakes

Abstract

The invention relates to the technical field of sewage treatment, and discloses an aquatic plant platform structure for sewage treatment of rivers and lakes. The aquatic plant platform structure comprises a fixed bottom plate, connecting members are fixedly mounted at the outer side of the fixed bottom plate, a floating cylinder is fixedly mounted at the bottom of every connecting member, a positioning cylinder is fixedly mounted in the fixed bottom plate, the top of the fixed bottom plate is fixedly provided with fixing tubes, an insert rod is inserted into the top end of every fixing tube, and a stopping member is fixedly mounted at the bottom end of every insert rod. Plant seedlings are placed through a receiving net, buoyancy is provided to effectively ensure that the whole platform isstably placed on the water surface, the roots of the seedlings go through a stopping cylinder and extend into a net cylinder during the growth of the plants, and the net cylinder can effectively protect the roots of the plant seedlings to ensure the normal growth of the aquatic plants, so the purifying treatment of sewage is effectively completed.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an aquatic plant platform structure based on river and lake sewage treatment. Background technique [0002] In the past ten years, with the rapid development of industry and agriculture, the amount of nitrogen and phosphorus discharged into rivers and lakes has continued to increase, and the excessive use of chemical fertilizers and pesticides in agricultural production has caused agricultural non-point source pollution and industrial chemical substances. Pollution has become the most important source of water pollution. According to statistics, the utilization rate of chemical fertilizers in my country is only about 30% on average, and only 10%-20% of the pesticides used are usually attached to crops. Under the effects of irrigation and precipitation, agricultural production A large amount of fertilizers and pesticides have entered the nearby rivers, causing eutrophicatio...
