Ecological tree pool system for intercepting rainwater surface runoff pollutants

Abstract

The invention relates to an ecological tree pool system for intercepting rainwater surface runoff pollutants, which comprises a prefabricated ecological tree pool, the prefabricated ecological tree pool is sequentially provided with a reservoir, an intercepting pool and a purifying pool from outside to inside, a first pool wall is arranged between the reservoir and the intercepting pool, the bottom of the first pool wall is provided with a filter grating, and the filter grating is communicated with the reservoir and the intercepting pool; a second tank wall is arranged between the interception tank and the purification tank, a plurality of overflow holes are formed in the second tank wall from bottom to top, and the overflow holes are communicated with the interception tank and the purification tank; the first pool wall is lower than the pool wall of the prefabricated ecological tree pool, and the second pool wall is lower than the first pool wall. By means of the underflow type structure, rainwater flows along a specific route, the purification effect is good, various pollutants can be effectively intercepted, and the ecological tree pool belongs to the technical field of ecological tree pools.

Description

technical field [0001] The invention relates to the technical field of ecological tree ponds, in particular to an ecological tree pond system for intercepting rainwater surface runoff pollutants. Background technique [0002] In recent years, with the rapid progress of urbanization, large-scale hardening pavement, the problem of lagging underground infrastructure construction has become increasingly prominent, resulting in a series of outstanding problems in the city, such as the inability of hardened pavement to penetrate rainwater, making the The collection of rainwater on the ground greatly increases the urban waterlogging; it also blocks the replenishment of groundwater by rainwater, making it difficult for the urban groundwater level to rise, directly affecting the health of vegetation, and aggravating the pollution of the water environment by pollutants carried by surface runoff. [0003] At present, relevant patented technologies have been formed in the treatment of s...
