Abstract

The invention discloses a rainfall flood regulating system which comprises a draining aisle, a rainwater inlet is formed in the left end of the draining aisle, an outlet for rainwater to be processed is formed in the right end of the draining aisle, a draining opening is formed in the front side of the draining aisle, a draining control weir gate is arranged at the draining opening, and a first level sensor is arranged in the draining aisle. A first regulation and storage tank and a second regulation and storage tank are arranged on the rear side of the draining aisle, a first overflow structure is arranged between the draining aisle and the first regulation and storage tank, a second overflow structure is arranged between the first regulation and storage tank and the second regulation and storage tank, a front water passing channel is connected between the first regulation and storage tank and the second regulation and storage tank, a one-way check valve is arranged on the front water passing channel, a submersible sewage pump is arranged in the first regulation and storage tank, and the water outlet end of the submersible sewage pump is connected with the draining aisle. Rainwater and the flood peak in the middle period are regulated in time while initial rainwater is separated, pollution of the initial rainwater and city and town waterlogging are effectively prevented, and regulation and storage are safe and reliable.

Description

technical field [0001] The invention relates to a drainage system, in particular to a rainwater control system. Background technique [0002] With the increase of urban air pollution and ground pollution, the pollution of rainwater runoff is becoming more and more serious, especially the initial rainwater with more pollutants. According to the survey, the highest value of pollutant indicators of early rainwater in some areas is much higher than that of typical urban domestic sewage , so it is very necessary to collect and treat the initial rain; in addition, when there is heavy or continuous rainfall, it is easy to form stagnant water, leading to urban waterlogging. [0003] At present, the rainwater is generally discharged into natural water bodies throughout the whole process, which will cause certain water pollution. With the strengthening of environmental protection awareness and the development of rainwater collection and utilization technology, in the drainage system,...
