Problems solved by technology

[0008] 2. The problem of single operation mode
[0009] 3. The problem of the buried depth of the storage tank
For storage tanks with sewage regulating and storage functions, especially the storage tanks in front of sewage plants, they basically have the characteristics of deep burial, thick covering soil, and high headroom. These characteristics will lead to high investment in the construction of storage tanks, On the other hand, problems such as difficulty in foundation pit support will also be detrimental to the stability of the main body structure of the storage tank. Problems such as high energy consumption and difficult operation

specific Embodiment approach

[0049] The sewage storage tank in the lower layer is mainly operated independently according to the working conditions of the sewage peak period and the sewage trough period, and is not affected by sunny and rainy days. The specific implementation methods are as follows:

[0050] 1. Lifting pump station mode: In the specific implementation mode, under normal circumstances, the lower layer of the storage tank is mainly used as the lifting pump station in front of the third phase of the sewage treatment plant. The flow-limiting valve in the grid well controls the 50,000 m 3 The sewage of / d is distributed to the lower layer of the storage tank by the sewage inlet pipe 2 of the lower layer, and the remaining sewage enters the first phase of the sewage treatment plant through the inlet pipe of the original sewage plant, and the sewage distributed to the storage tank is lifted to the storage tank by the drainage pump at the lower layer of the storage tank The water outlet main pipe...

Abstract

The invention discloses a multifunctional double-layer storage pond suitable for a high-density built-up area. The storage pond comprises an upper rainwater storage pond and a lower sewage storage pond which are arranged in a separated mode through a partition plate and distributed up and down, wherein the water inlet end of the rainwater storage pond is sequentially connected with an upper rainwater inlet pipe, a coarse screen, a sand fishing device, a fine screen and an upper water collection pit; the water inlet end of the sewage storage pond is sequentially connected with a lower sewage inlet pipe and a lower water collection pit; and the rainwater storage pond and the sewage storage pond communicate through an access hole formed in the side wall of the rainwater storage pond. The double-layer storage pond has the advantages of being stable in structure, low in energy consumption, high in occupied land utilization rate, high in pond body utilization rate, high in use frequency andguarantee rate and the like.

Description

technical field [0001] The invention belongs to the technical field of rain and sewage regulation and storage, and in particular relates to a multifunctional double-layer regulation and storage pond suitable for high-density built-up areas. Background technique [0002] At present, the role of storage ponds in China is mainly reflected in two aspects: initial rainwater regulation and storage and sewage peak regulation and storage. [0003] Initial rainwater generally refers to a part of the rainwater runoff formed by rainfall scouring the ground at different catchment surfaces. It is an empirical concept derived from the scouring law under specific rainfall conditions. Scouring has the characteristics of high pollutant concentration, large changes in water quality, and large instantaneous flow. This part of highly polluted rainwater enters the river through the rainwater system, seriously affecting the water quality of the river. [0004] Rainfall in some areas in my countr...
