Floating type ecological water purification plant

Abstract

The invention provides a floating type ecological water purification plant comprising a double-layer buoyancy framework, a surface layer purification zone and a bottom layer purification zone, wherein the double-layer buoyancy framework comprises an upper layer framework and a lower layer framework which is fixedly connected with the upper layer framework by virtue of a connecting part; the surface layer purification zone is formed by filling the whole or partial area of the upper layer framework with a water purification packing; the bottom layer purification zone is formed by filling the whole or partial area of the lower layer framework with a water purification packing. In a working state, the upper layer framework floats above the water surface, and an emergent aquatic plant is planted on the water purification packing of the surface layer purification zone; and the lower layer framework is positioned below the water surface, and a submerged plant is planted on the water purification packing of the bottom layer purification zone. The floating type ecological water purification plant provided by the invention is additionally provided with the lower layer framework and the submerged plant, so that the floating type ecological water purification plant has a great function on elimination of endogenous pollution caused by substrate sludge, prevention and control of algae blooms, improvement of water quality and promotion of water ecological restoration.

Description

technical field [0001] The invention relates to the technical field of surface water purification treatment and ecological restoration, in particular to a floating ecological water purification plant. Background technique [0002] In recent years, with the development of the economy, most cities in my country have built sewage treatment plants and reclaimed water plants. The construction of sewage treatment projects has played a major role in improving the water environment. However, problems also arise. The tail water discharge form of the sewage treatment plant is mainly centralized discharge. Due to the unreasonable setting of the tail water discharge outlet (such as too concentrated), the initial dilution factor of the discharged sewage is low. Compared with the "Surface Water Environmental Quality Standard" (GB3838-2002), according to the Class A standard, which is the highest discharge requirement, the tail water of urban sewage treatment plants still belongs to the ce...

Problems solved by technology

The effective components of the above two water purification systems are concentrated in the water surface or shallow water area, far away from the bottom mud and overlying water, so the purification efficiency of the endogenous pollution is poor
