Artificial-meadow ecological floating bed

Abstract

The invention provides an artificial-meadow ecological floating bed, comprising a floating bed, a purification system, an oxygen supply system and a control system, wherein the purification system comprises emergent aquatic plants, float grass, health cotton, effective microorganisms and a biological enzyme; the emergent aquatic plants are planted on the floating bed; the float grass and the health cotton are connected under the floating bed; the effective microorganisms and the biological enzyme are attached to the root system of the emergent aquatic plants, the float grass and the health cotton; the oxygen supply system comprises a pressure fan, an air supply pipe network and aerating and oxygen dissolving equipment; the pressure fan is connected with the aerating and oxygen dissolving equipment through the air supply pipe network and the aerating and oxygen dissolving equipment is arranged under the float grass; the control system comprises a PLC (Programmable Logic Controller) and an automatic control valve; the PLC is electrically connected with the pressure fan, the aerating and oxygen dissolving equipment and the automatic control valve, respectively; and the automatic control valve is arranged at the outlet of the aerating and oxygen dissolving equipment. According to the invention, the purification system which is efficient, energy-saving, green and environment-friendly and high in purification efficacy can be integrally built in water; and therefore, the problem of water eutrophication can be solved.

Description

technical field [0001] The invention relates to the field of eutrophic water body treatment, in particular to an artificial meadow ecological floating bed for the treatment and restoration of eutrophic water body. Background technique [0002] At present, domestic urban and new rural living and production sewage collection pipe networks and sewage treatment facilities are temporarily unable to achieve 100% centralized collection and centralized treatment of sewage. Residents, collectives, enterprises, and communities do not have reliable and effective living and production sewage treatment facilities. Therefore, they do not have a good way of intercepting domestic and production sewage from the source of pollution, which is likely to cause eutrophication of urban river water. If the river sewage problem is not effectively resolved for a long time, it will inevitably seriously endanger the surface water system, groundwater system, natural environment and human health.
