Problems solved by technology

However, for eutrophic and heavily eutrophic water bodies, the transparency of the water body is low, and the bottom light is obviously insufficient, which limits the growth of large aquatic plants, especially submerged plants.
When the light intensity at the bottom of the water is lower than the light compensation point of the plant, it will make it difficult for submerged plants to survive and the community cannot form

Abstract

The invention discloses a preparing and purifying method of dealing modularization air-float artificial mattress of wastewater, wherein the main frame of bed display member frame structure as cube box; the bottom, angle and side wall connected with pipes; the top open up to the air; the grid plate is set on the bottom of the bed; the planting box is set on the grid plate; planting vegetation through the planting hole; setting several floats on the side wall; counteracting the weigh of bed body with floatage; keeping balance of bed body in the water; installing ports for passing water on the bottom of float bowl with at least 2 float bowl on the holder; inserting gas-filled lamp into float bowl through ports for passing water; equipping inflating gate valve on the other side of gas-filled lamp. The invention possesses rational structure and simply production, which can improve the survival rate of water plant.

Description

technical field [0001] The invention relates to a sewage biological treatment facility, in particular to a sewage biological treatment modular air flotation artificial sedimentation bed and a manufacturing method and a purification method. Background technique [0002] Since the 1970s, the bio-ecological water body restoration technology centered on large aquatic plants has attracted people's attention and has become a research hotspot in the field of water environment technology. However, for eutrophic and heavily eutrophic water bodies, the transparency of the water body is low, and the bottom light is obviously insufficient, which limits the growth of large aquatic plants, especially submerged plants. When the light intensity at the bottom of the water is lower than the light compensation point of the plant, it will make it difficult for submerged plants to survive and the community cannot form. During plant transplantation, the deeper the water, the faster the plant wil...
