Aquatic plant maintenance system for constructed wetland for municipal greening

Abstract

The invention relates to an aquatic plant maintenance system for constructed wetland for municipal greening. The system comprises a water injection tank, a primary sedimentation tank, an anaerobic biochemical tank, a primary filter tank, a constructed wetland pool, a secondary filter tank, an aerobic biochemical tank, a regulating tank, a secondary sedimentation tank and a circulating tank which are sequentially connected through pipelines, the circulating tank is connected with the primary sedimentation tank, and the regulating tank is connected with a dosing tank; a planting floating bed is arranged in the constructed wetland pool and floats on the constructed wetland pool; a transverse rod is arranged in the constructed wetland pool and located below the planting floating bed, a plurality of vertical rods are connected to the transverse rod, the free end of each vertical rod is connected with a floating ball through a thin rope, the floating balls are filled with aquatic plant nutrition bags, and a rotating piece is connected to the bottom of the constructed wetland pool; and the rotating piece is connected with the cross rod and drives the cross rod to rotate in the constructed wetland pool. The system has the effects of protecting the root systems of the aquatic plants, being high in removal efficiency of organic pollutants, being high in purification effect and assisting in building and improving an ecological cycle system.

Description

technical field [0001] The present application relates to the technical field of municipal greening, in particular to a water and grass conservation system for artificial wetlands of municipal greening. Background technique [0002] With the development of economy and society, all kinds of pollution in the city are constantly aggravating, and the environmental problems of the city are getting more and more attention. As an important part of urban greening, municipal trees, lawns, flowers, etc. It is important to note that artificial wetlands are artificially constructed grounds similar to natural wetlands, consisting of plants (aquatic plants or marsh plants, etc.), microorganisms (bacteria and fungi, etc.) and filler substrates (gravel, ceramsite, etc.) Interdependent elements make up the wastewater treatment ecosystem. [0003] Wherein aquatic plants are very useful plants, it can not only greatly improve the ornamental value of fish, but also can promote the growth and r...

AI Technical Summary

Problems solved by technology

[0003] Wherein aquatic plants are very useful plants, it can not only greatly improve the ornamental value of fish, but also can promote the growth and reproduction of tropical fish, aquatic plant cultivation is very important; although the municipal greening aquatic plant conservation system of prior art has carried out protection to aquatic plants , but when aquatic plants grow, they may be infected by bacteria and cause withering and death, which will affect the effect of purifying water quality
