In-situ circulating treatment system for landscape lake water

Abstract

The invention discloses an in-situ circulating treatment system for landscape lake water, and belongs to the technical field of landscape water purification. The system is composed of a surface runoff collecting tank, an ecological percolation tank, an enhanced purification unit, a circulating power system and a landscape lake water main body water area, wherein the enhanced purification unit consists of a bottom aeration device and a biological purification unit; the circulating power system consists of a circulating power pump and a circulating pipeline; an ecological box and a multi-stage aeration device are arranged in the landscape lake water main body water area; the surface runoff collecting tank is positioned at the lowest position of a landscape lakeshore terrain and is communicated with the ecological percolation tank; the ecological infiltration tank is arranged along the inner side of a landscape lakeshore; the enhanced purification unit is arranged near the communicating part of the surface runoff collecting tank and the ecological percolation tank; and the circulating power system is located in the center of the landscape lake body water area. The ecological percolation tank, a biological floating bed and the ecological box are all made of sponge concrete and have good water permeability, air permeability and water binding capacity. The system is suitable for various urban landscape lakes, realizes in-situ treatment of landscape lake water, improves the quality of the landscape lake water and increases the life happiness index of residents according to the water quality characteristics of the landscape lake water and the green and ecological design concepts, and has the advantages of low operation cost, easiness in control, environment friendliness and the like.

Description

technical field [0001] The invention relates to an in-situ circulation treatment system for landscape lake water, belonging to the technical field of landscape water purification. Background technique [0002] With the continuous improvement of people's living standards in our country, local governments have added a large number of landscape lakes in order to meet people's living needs and strengthen the ecological construction of cities. As the receiving body of urban surface runoff, landscape lakes accumulate organic matter, nitrogen and phosphorus and other pollutants in the water. At the same time, the water in landscape lakes does not flow, the water body has poor self-purification ability, and the dissolved oxygen content in water bodies is low. Therefore, it is very easy to produce eutrophication of water body and black and smelly water body, which seriously affects people's quality of life and urban water ecological landscape. In order to improve the water quality o...
