Biofiltration bed-ecological floating bed eutrophication landscape water treatment system

Abstract

The invention belongs to a biofiltration bed-ecological floating bed eutrophication landscape water system and especially relates to a biofiltration bed-ecological floating bed eutrophication landscape water treatment system. The biofiltration bed-ecological floating bed eutrophication landscape water treatment system comprises a water gathering zone, a biofiltration reaction zone, an ecological floating bed zone and a reoxygenation zone. The upper part of the water gathering zone is provided with a water inlet, a fine grating net is arranged at the water inlet, the bottom of the water gathering zone is provided with a sand settling bucket, the upper part of the outer side wall of the water gathering zone is provided with multiple diversion apertures side by side, the water gathering zone is communicated with the biofiltration reaction zone by the diversion apertures, the biofiltration reaction zone is filled with a filler, the bottom of the biofiltration reaction zone is provided with an aeration device, the middle of the outer side wall is provided with liquid diversion trenches, the liquid diversion trenches are communicated with the ecological floating bed zone, the ecological floating bed zone is provided with a constructed wetland filter layer, the upper part of the ecological floating bed zone is provided with a water distribution system, and a water outlet pipe is arranged in the reoxygenation zone. The biofiltration bed-ecological floating bed eutrophication landscape water treatment system realizes combination of advantages of biofiltration reaction and ecological floating bed, utilizes reoxygenation, realizes thorough treatment on eutrophication landscape water, has a simple structure, is simple in operation and maintenance, has a low investment and operation cost and has no secondary pollution.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a biological filter bed-ecological floating bed eutrophication landscape water body treatment system. Background technique [0002] Landscape water bodies refer to water bodies that are naturally formed or artificially constructed to give people an aesthetic feeling in cities, villages and tourist attractions, such as large and small lakes, artificial lakes, urban rivers, etc. Landscape water is of great significance to improve the quality of urban environment, enhance the comfort of living, and improve the microclimate in urban areas. [0003] With the improvement of the level of urbanization, the degree of eutrophication of urban landscape water body is deepening day by day, causing potential harm to the ecological environment and human health, and the treatment of eutrophic landscape water body has attracted more and more attention. [0004] Water pollution preventio...
