Embodiment Construction

[0016] The following will be described in detail through examples.

[0017] The project site is a river improvement and landscape construction project in a certain area in the south to protect drinking water sources. The main pollutants in the river are N and P pollutants, which come from upstream urban runoff, sewage treatment plant drainage and some agricultural and rural runoff. The runoff is perennial It is 20,000 cubic meters per day, and it can reach 100,000 cubic meters per day during the rainy season. The height difference between the water inlet and outlet of the project site is about 20m, the project area is about 100,000 square meters, the land area is about 80,000 square meters, and the rest is water surface. There are two rivers, which converge at the end of the project section. According to the existing land status quo, the present invention is realized through the following technical means.

[0018] 1. Due to the large difference in water flow drop and seasonal...

Abstract

The invention belongs to a non-point source pollution control technique, and particularly relates to a landscape park type surface runoff treatment system. The landscape park type surface runoff treatment system mainly comprises an ecological landscape pond, a runoff treatment landscape land, ecological diversion canals and auxiliary park facilities. The landscape park type surface runoff treatment system is located at the tail end of rural and urban sewage or surface runoff with high pollutant concentration, a river is required to be wide, and a large-area waste land or natural wetland is required to be available. According to the system, sewage is respectively diverted into the runoff treatment landscape land and the ecological landscape pond via the ecological diversion canals, treated and then converged into the original runoff. Aiming at surface runoff, particularly rural and urban surface runoff with high pollutant concentration, the landscape park type surface runoff treatment system sufficiently develops the self-cleaning capability of soil lands and plants in combination with various suitable technical means to achieve the dual effects of pollutant treatment and landscape beautification, and can be used for treating rural agricultural runoff, urban runoff, tail water of sewage treatment plants and the like.

Description

technical field [0001] The invention belongs to the technical field of surface source pollution (non-point source) control, and specifically relates to a landscape park-style surface runoff treatment system, which is suitable for the treatment of rural agricultural runoff, urban runoff, and tail water drainage of sewage treatment plants. Background technique [0002] The continuous development of productivity has changed the way of life of human beings. When human beings pursue material life, they also have higher and higher requirements for the production and living environment. In the process of pursuing material life and requiring more means of production and living, human beings produce more and more production and domestic waste (including waste water, waste residue and waste gas, etc.), and flow into the natural environment, causing greater environmental pressure on nature. , while human beings satisfy their own survival needs, they also hope that their living environm...
