Multidimensional ecological drainage system for intercepting and controlling separate system rainwater pollutants into river

Abstract

The invention discloses a multidimensional ecological drainage system for intercepting and controlling separate system rainwater pollutants into a river. The system is arranged on one side of a river bank and takes a stair-step shape along the river bank; rainwater in pipe networks flows into a first-stage water drop platform by rain-water pipes, enters a storage pond, flows into an ecological buffer zone by a second-stage water drop platform, and lastly flows into a plant growth detention pond; and the first-stage water drop platform and the ecological buffer zone are slope-shaped, and plants are planted in the plant growth detention pond. The system not only ensures drainage, but also reduces the risk that rainwater polluted run-offs directly flow into the river, reduces impact and damage to water quality of the water body in a river channel, effectively controls the pollutants in the river, effectively improves the water environment, and enhances the urban water landscape value.

Description

technical field [0001] The invention belongs to the technical field of environmental protection engineering and water treatment, and in particular relates to an ecological drainage system integrating multi-dimensional infiltration and retention, which is used for interception and control of pollutants from rainwater entering rivers by diversion. Background technique [0002] In recent years, the pollution of urban water bodies in my country has been quite serious, and many rivers and lakes are in a relatively serious state of pollution, and there is a tendency to continue to intensify. The pollution of rainwater runoff in most cities is relatively serious, which has become the primary factor for the deterioration of urban river and lake water quality. Some urban runoff after the rain is directly discharged into the river without any treatment, and the direct flow of rainwater pollution into the river will form a pollution impact load, resulting in sudden water quality deteri...
