Problems solved by technology

[0005] The technical problem to be solved by the present invention is that in the prior art, the sewage input from the sewage storage facilities directly enters the confluence pipe for output, which is very easy to cause serious pollution of natural water bodies in rainy days, or the treatment pressure of sewage treatment facilities is too high , waste of resources and other technical defects

Embodiment 1

[0030] For details, please refer to the attached Figure 1-3 In the embodiment of the sewage regulating and storing device, the sewage regulating and storing device at least includes an adjusting part 10, a buffer part 40 and a vacuum pump 130.

[0031] Wherein, the adjustment part 10 has an adjustment space inside which can be used to contain sewage, and is respectively connected with the sewage outlet of the unit area and the confluence pipe 30; the size and volume of the adjustment part 10 are not limited by the present invention, and can be based on actual conditions. Flexible design is sufficient for job requirements. Similarly, the buffer part 40 also has a storage space 401 that can be used to store the above-mentioned sewage, and is connected to the adjustment part 10; the size and volume of the storage space 401 are not limited by the present invention, and can be flexibly designed according to actual operation requirements. can. Therefore, the buffer part 40 and the a...

Embodiment 2

[0081] With the same inventive concept as the first embodiment, the second embodiment of the present invention also provides a method for regulating and storing sewage based on vacuum water inlet and gravity water outlet, which is applied to the device described in the above embodiment 1, and the method includes:

[0082] Receive the identification instruction of whether the buffer part needs water out, if yes, control the first switch and the third switch to open, and the second valve to open, so that the sewage in the buffer part flows into the regulating part under the action of gravity and is discharged from the confluence pipe ;

[0083] Receiving an identification instruction of whether the buffer unit needs to store water, and if so, controlling the first switch to turn off;

[0084] Vacuum the buffer department so that the adjustment space and the storage space form an air pressure difference;

[0085] The sewage is pressed into the buffer part by the regulating part under the...

Abstract

The invention provides a double-area sewage regulation and storage device and method. The device comprises a regulation portion, a buffer portion and a vacuum pump, wherein the buffer portion communicates with the regulation portion and is located above the regulation portion, so that a height difference is formed between two areas in a double-area structure; and the vacuum pump communicates withthe buffer portion. When water enters the buffer portion, air in the buffer portion is pumped out through the vacuum pump, and sewage in the regulation portion flows into a storage space under the effect of an air pressure difference; when water flows out of the buffer portion, the buffer portion communicates with the external atmospheric pressure, and the sewage in the storage space flows into aregulation space under the effect of gravity. According to the double-area sewage regulation and storage device and method, the technical defects that in the prior art, a natural water body is severely polluted in rainy days easily due to the structure design that input sewage directly enters a confluence pipe and is output, or the treatment pressure of sewage treatment facilities is excessively high, and resources are wasted are avoided, the technical effect that sewage is regulated and stored when no sewage emission is needed can be achieved, and the double-area sewage regulation and storagedevice and method have the characteristics of simple structure, convenient operation and wide applicability.

Description

Technical field [0001] The invention belongs to the technical field of drainage, and particularly relates to a dual-zone sewage storage device and method. Background technique [0002] The urban pipeline network is divided into a combined drainage system and a split drainage system, which are used to discharge sewage (such as domestic sewage) in the unit area. In the existing discharge process, the sewage in the unit area is first transported to the sewage branch pipe The sewage storage facility is collected and chemically treated (such as chemical decomposition in the sewage storage facility), so that the treated upper liquid flows into the municipal pipeline through the confluence pipe for subsequent treatment. [0003] However, this type of discharge method makes the sewage discharged from the sewage storage facility directly enter the junction pipe and mix with rainwater during sewage discharge, and if the mixed water of rainwater and sewage is directly discharged into the natu...
