Embodiment 1
[0080] refer to Figure 1-Figure 2 , a kind of regulation and storage purification system of the present embodiment to control rain and sewage confluence and overflow pollution, including water inlet corridor 1, grid room 2, sewage pumping station 3, deodorization room 4, regulation and storage sedimentation tank 5 and water storage Type ecological filter 6.
[0081] The water intake corridor 1 includes the water inlet 11 of the sewage pumping station, the water inlet 12 of the regulating and storage sedimentation tank, the water inlet 13 of the ecological filter and the emergency overflow 14 of the emergency overflow to the water body under the heavy rain condition, wherein the sewage pumping station The elevation of the bottom of the water inlet 11 is flush with the bottom of the water inlet corridor 1, and the water inlet 11 of the sewage pump station is connected to the grill room 2 through a pipeline, so that the high-concentration rain-sewage combined sewage in sunny day...
Embodiment 2
[0097] Carry out experimental research on the treatment of urban rainwater and sewage mixed sewage in Yueyang City, carry out experiments in the areas around the three major lakes in Yueyang where there are rainwater and sewage overflow pollution, and build the above-mentioned regulation, storage and purification system to control rainwater pollution and overflow pollution.
[0098] The original structure is the combined drainage pipe, the sewage pumping station of the sewage treatment plant and a simple storage pond. The simple storage pond is an open-air pond, which only temporarily stores the confluent sewage in the rainy season. Because the sewage is not classified and graded, the pool capacity is very large, 2000m 3 . When the rainy season comes, all the combined sewage that exceeds the treatment capacity of the sewage pumping station flows into the storage pond. After the rain stops, the sewage in the storage pond is pumped into the sewage treatment plant one after anot...
