Problems solved by technology

[0004] The main purpose of the present invention is to solve the problem that the floating bed cannot survive the winter. Taking the slightly polluted water sources (not industrial sewage and urban domestic sewage) in lakes, reservoirs, rivers and other water bodies in our country as the treatment object, using aquatic plants to purify water quality technology, modular floating bed type The sewage purification device has the characteristics of simple structure, easy installation, long service life, low cost, and convenient movement. It provides a device that can be raised and lowered on the water surface, and can be submerged underwater in winter, which can prevent the bed from being damaged by freezing, and make the plants in the water. Overwintering underwater and reusable biological treatment of sewage can be raised and lowered artificial plant floating bed and its production method and use method

Abstract

This invention discloses a method for producing rise-fall artificial plant floating bed for wastewater biological treatment. The main body of the floating bed is hollow and sealed, and a planting groove is set on the main body. Filler and plants are placed in the planting groove. A support is set in the planting groove, which is connected with water body. Bed connectors are placed surrounding the main body of the floating bed. At least two main bodies are combined to form the floating bed, which is placed on the water surface. The roots of the plants on the floating bed can realize filtration, absorption and adsorption of pollutive substances in wastewater. The floating bed is sinked into the non-frozen layer below water surface in winter, and taken out of water surface inspring. The plants are left for further filtration, absorption and adsorption of pollutive substances in wastewater. This invention has such advantages as short project period, and rapid acting. Plants of the floating bed have a survival period of more than 8 months / year. The planting can match city landscape, thus are good for city afforestation, and can reduce secondary assembly cost. The floating bed just needs replanting in spring.

Description

technical field [0001] The invention relates to a sewage biological treatment facility, in particular to a sewage biological treatment liftable artificial plant floating bed, a manufacturing method and a using method. Background technique [0002] Water pollution will cause the degradation of the ecosystem and the reduction of biodiversity in rivers and lakes. At present, the quality of surface water in many areas of our country is poor, and it is showing a deteriorating trend. The pollution of rivers flowing through large cities is particularly serious. Ecological deterioration At the same time, it seriously affects the landscape of the city. Usually, urban sewage treatment plants treat industrial and urban domestic sewage as the treatment object, and the effluent water quality is the second-level standard. Treatment, using artificial floating bed for sewage treatment technology is to use the bed body and plant roots to filter and absorb pollutants in sewage, which can gre...
