Example Embodiment

[0058] Example 1:

[0059] see Figure 1-5 , a drainage system for improving the operating efficiency of pollution control facilities, which includes a rainwater collection unit 1 for collecting rainwater and sewage, and the rainwater collection unit 1 is connected to a receiving water body through a discharge unit 3; the rainwater collection unit The unit 1 is connected with a storage tank unit 4 for water storage; the rainwater collection unit 1 is connected with a sewage treatment unit 2 for treating sewage, and the discharge end of the sewage treatment unit 2 is connected with the receiving water body ; Also includes a scheduling unit 5 for controlling scheduling. In the specific use process, the pollutant-holding capacity calculation module of the dispatching center unit calculates the dynamic pollutant-holding capacity of the receiving water body, the pollutant discharge allocation module forms a dynamic allocation of sewage discharge according to the distribution mecha...

Example Embodiment

[0060] Example 2:

[0061] see figure 2 , the rainwater collection unit 1 includes a plurality of sewage production areas 12, all of the sewage production areas 12 are connected to the confluence pipeline 11 through communication pipes;

[0062] Further, the pipe diameter of the confluent pipeline 11 is designed and constructed according to the highest peak value of the dischargeable sewage generation area 12 in the long term plus a certain amount of rainwater, and a certain amount of rainwater is at least twice the highest peak value of sewage; generally When, especially during the peak period of sewage generation in non-morning and late periods, there is a large vacant space in the confluence pipeline.

[0063] On sunny days, there is only sewage in the sewage generating area 12 in the confluent pipeline 11, and after being treated by the sewage treatment unit 2, the tail water is discharged into the receiving water body;

[0064] When it rains, the confluent pipeline 11 ...

Example Embodiment

[0065] Example 3:

[0066] see image 3 , the sewage treatment unit 2 includes a lifting pump group 21, the lifting pump group 21 is connected to the pretreatment device 23 through the inlet pipe 22, the pretreatment device 23 is connected to the biochemical treatment device 24 through the connecting pipe 26, and the drainage of the biochemical treatment device 24 The mouth is connected with a tail water outlet pipe 25.

[0067] Further, a control switch 28 is installed on the connecting pipe 26 , an override pipe 27 is installed between the pretreatment device 23 and the tail water outlet pipe 25 , and an override switch 29 is installed on the override pipe 27 .

[0068] Further, the lifting pump group 21 is composed of conventional water pumps with various water outputs, and a spare water pump with redundant capacity is also provided.

[0069] After the sewage or combined sewage is treated by the pretreatment device, its discharge concentration can be reduced; after being ...

Abstract

The invention discloses a drainage system and a scheduling method for improving the operation efficiency of a pollution treatment facility, and the drainage system comprises a rainwater and sewage collection unit which is used for collecting rainwater and sewage and is connected with a receiving water body through a discharge unit. The rainwater and sewage collection unit is communicated with a storage pond unit for storing water. The rainwater and sewage collection unit is connected with a sewage treatment unit for treating sewage, and the discharge end of the sewage treatment unit is connected with a receiving water body. The system further comprises a scheduling unit used for performing control scheduling. The water storage capacity of the storage pond unit is reduced by utilizing the pollutant-holding capacity of the receiving water body and the treatment capacity of the sewage treatment unit, so that the operation energy consumption of the storage pond unit is reduced, and the industrial utilization value is high.

Description

technical field [0001] The invention relates to the technical field of ecological and environmental protection engineering, in particular to a drainage system and a scheduling method for improving the operating efficiency of pollution control facilities. Background technique [0002] The urban drainage system is an important facility for urban water environment governance and to ensure that the receiving water body achieves the management and control goals. In order to further reduce the pollution of sewage and rainwater to the urban water environment, the urban drainage system has added many treatment facilities; In the drainage system, building additional combined sewage storage tanks has become one of the main means. Generally, the storage tank is started at the beginning of the rainfall, and part of the combined sewage is introduced into the storage tank. After the rainfall is over, the combined sewage in the storage tank is transferred to the sewage treatment facility. ...
