Ecological tree pool and working method of automatic control of initial rainwater abandonment by float

Abstract

The invention relates to the field of rainwater control and rainwater utilization and discloses an ecological tree pool with a floator controlling an abandoned flow of initial rainwater automaticallyand a working method. The ecological tree pool comprises the floator, an abandoned flow drainage ditch and a water distribution area, wherein a flow inlet is formed in one end of the abandoned flow drainage ditch while the other end of the abandoned flow drainage ditch communicates to a drainage pipe, a first through hole matched with the floator is formed in the bottom surface of the abandoned flow drainage ditch, a detention storage space is arranged in the water distribution area below the abandoned flow drainage ditch, the floator is arranged in the detention storage space, the floator canmove up and down in the first through hole, and the upper surface of the floator is aligned to the bottom surface of the abandoned flow drainage ditch or is higher than the bottom surface of the abandoned flow drainage ditch. According to the working method of the ecological tree pool, automatic flow abandonment is achieved based on the floator, and the floator can reset automatically after rainfall, so that manual operations are not needed, and the flow is abandoned efficiently. Problems that initial runoff pollutants may lead to blockage in operation of the tree pool and damage arbor plantsand snowmelt runoff affects operation of a facility and the like are solved effectively.

Description

technical field [0001] The invention relates to the technical field of rainwater control and rainwater utilization, in particular to an ecological tree pond and a working method in which floats automatically control initial rainwater abandonment. Background technique [0002] Urban stormwater runoff carries a large number of different types of pollutants, which is one of the key factors threatening the quality of urban water environment. A large number of studies have shown that for runoff from sources such as roads and roofs, the initial erosion of pollutants is usually more obvious. That is to say, the initial concentration of runoff pollutants in this type of catchment is significantly higher than that in the later runoff period, and the smaller volume in the early runoff period carries a larger proportion of the pollution load of the entire rainfall. Therefore, if the initial rainwater runoff pollution can be effectively controlled, it can be extremely economical and ef...
