The invention provides an initial rainwater partitioned regulation and storage system, relates to the field of urban initial rainwater treatment, and aims to solve the problem that resources are wasted due to insufficient treatment scale of a sewage treatment plant. According to the technical scheme, the system comprises a water inlet pipe, a first regulation and storage area, a first regulation and storage area water pump, an overflow weir, a filter layer, a second regulation and storage area, a second regulation and storage area water pump and a water outlet pipe. The water inlet pipe communicates with the first regulation and storage area, the first regulation and storage area water pump is arranged in the first regulation and storage area, the second regulation and storage area water pump is arranged in the first regulation and storage area, and the overflow weir and the filter layer are arranged between the first regulation and storage area and the second regulation and storage area. By means of the system, different treatment modes are adopted for initial rainwater with different rainfall depths, the precipitation within 2-4 mm can be sent to a sewage treatment plant for treatment, and the rest of initial rainwater can be simply treated nearby, so that the problem of insufficient treatment scale of the sewage treatment plant is avoided, and the utilization rate of the existing treatment process is increased.
Description
technical field [0001] The invention relates to an initial rainwater district regulation and storage system, in particular to a field of urban initial rainwater treatment Background technique [0002] In the early stage of rainfall, the rainwater washes away the underlying surfaces such as roofs and roads, carrying a large amount of pollutants from washing, forming the initial rainwater. Initial rainwater treatment has been widely carried out in the society. According to the "Outdoor Drainage Design Code" (GB50014-2006) (2016 Edition), it is recommended that the amount of water storage should be calculated according to rainfall. They are all selected according to 4~8mm. [0003] At present, most of the initial rainwater treatment methods are stored in storage tanks in rainy days and transported to sewage treatment plants for treatment in sunny days. However, the initial rainwater calculated according to the specifications is huge, far exceeding the treatment scale of urban ...
