Aquatic plant platform for river and lake sewage treatment

Abstract

The invention relates to the technical field of river sewage treatment, and discloses an aquatic plant platform for river and lake sewage treatment. The platform comprises two cross bars and bottom plates, wherein two sides of the two cross bars are supported and fixed above the bottom plates through supporting rods, and a planting structure and a floating structure are arranged below the cross bars. The planting structure comprises first growth plates, a second growth plate, vertical bars, clamping grooves, growth cylinders, a plate groove, a ring plate, a cylinder groove and through holes; aplurality of vertical bars are vertically welded at the bottoms of the cross bars on the front side and the rear side, and the first growth plates are arranged between the vertical bars on two sidesbelow the cross bars. The first growth plates and the second growth plate are slidably limited by arranging the cross bars and the vertical bars, and foam blocks are embedded and fixed on the sides ofthe two plates, so that positions of planting plants can be limited, and growth height of the plants can be adjusted according to water surface height, and the purification effect of the plants on sewage is ensured.

Description

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

AI Technical Summary

Problems solved by technology

[0003] In the prior art, plants are planted on aquatic plant platforms to purify sewage. However, when plants are planted on a fixed platform, the growth height of plants cannot be adjusted according to the water level. However, if plants are planted on a floating platform , will cause the plants to drift away with the water flow, affecting the purification effect
