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...

Abstract

The invention discloses a regulation, storage and purification system and method for controlling rainwater and sewage confluence overflow pollution. A water inlet gallery comprises a sewage pump station water inlet, a regulation and storage sedimentation tank water inlet, a water storage type ecological filter tank water inlet and an emergency overflow port which are sequentially increased in height, and the water inlet gallery also comprises a regulation and storage sedimentation tank clarification overflow port connected with the water storage type ecological filter tank, so that a gradientline for graded treatment according to rainfall is formed, wherein the gradient line comprises a rain-free or small-rainfall line comprising the water inlet gallery, a sewage pump station and a sewagetreatment plant, a medium rainfall line comprising the water inlet gallery, a regulation and storage sedimentation tank and a sewage treatment plant, a long-time continuous moderate rain line comprising the water inlet gallery, the regulation and storage sedimentation tank, the water storage type ecological filter tank and a natural water body, a heavy rainfall line comprising the water inlet gallery, the water storage type ecological filter and the natural water body, and a rainstorm line comprising the water inlet gallery and an emergency overflow port for overflowing water to the natural water body; a later line comprises all the lines. According to the system, the pollution load of discharged water is greatly reduced under the condition of limited regulation and storage volume, and the system is economical and efficient.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and specifically relates to a combined system overflow pollution control system, which strengthens the control of drainage pollution in rainy seasons through storage and purification measures, improves the environmental quality of surface water, and can be applied to black and odorous water treatment and sponge city construction. Background technique [0002] At present, most of the old urban areas in my country still adopt the combined drainage system of rain and sewage, and the combined drainage system will exist for a long time before the separate system transformation is completely realized in each area. When the rainstorm in the rainy season exceeds the design capacity of the combined pipeline, the excess rain-sewage mixed sewage overflows from the overflow facility or the drainage pumping station of the combined pipeline into the urban water body. These overflows are usually called ...
