Integrated microenvironment high-efficiency ecological filter bed system

Abstract

The invention discloses an integrated microenvironment high-efficiency ecological filter bed system. The system uses a PVC pipe as a support and integrates an ecological floating bed, a biological filling material, a biological filter material and blast aeration equipment to realize cooperative high-efficiency purification of contaminated surface water bodies like a river, a lake and a reservoir. The upper part of the ecological filter bed system is provided with the ecological floating bed to plant perennial aquatic water-purifying plants with strong stress resistance; the central part of the ecological filter bed system is provided with the porous netted filling material; and finally, the PVC pipe is used as the support to connect and secure the upper part, the central part and the lower part of the ecological filter bed system. The ecological filter bed system has the following advantages: the ecological filter bed system can be directly applied to sludge in surface water bodies like the river, the lake and the reservoir and to subsequent treatment after advanced treatment of effluent of domestic and industrial wastewater, has a certain landscape effect and a wide application scope, belongs to in-situ restoration technology for water bodies, poses no secondary pollution to surroundings and has low construction, operation and maintenance cost.

Description

technical field [0001] The invention relates to a surface landscape water ecological restoration system, in particular to an integrated microenvironment high-efficiency ecological filter bed system. Background technique [0002] Restoration of polluted rivers, lakes and reservoirs is an urgent need for social and economic development and ecological environment construction. In particular, the pollution control projects along the eastern route of the South-to-North Water Diversion Project have a large volume and a wide area, and it is imminent to find advanced, practical and low-cost technologies. Water pollution in rivers, lakes and reservoirs in my country mainly includes two aspects: nitrogen, phosphorus and other nutrients and organic matter pollution. In addition, cyanobacteria and red tides in lakes and reservoirs have also caused serious harm to water ecology and human health. For the control of eutrophication, developed countries mainly control nutrient salts, and m...

Problems solved by technology

At present, there are three main types of technologies used in the world: 1) chemical methods: such as adding chemical agents to kill algae, adding iron salts to promote the precipitation of phosphorus, adding lime to denitrify, etc., but it is easy to cause secondary pollution; 2) physical methods: dredging Sediment, mechanical algae removal, water diversion and silting, etc., but often treat the symptoms but not the root cause; 3) Biological-ecological methods: such as stocking algae-controlling organisms, constructing artificial wetlands and aquatic vegetation
