Embodiment 1

[0105] Depend on Figure 4 As shown in the schematic structural diagram of a split-flow drainage pipe network system for controlling domestic sewage and initial rainwater pollution, it can be seen that the present invention includes a plurality of unit areas A, a sewage main pipe B-1 and a rainwater main pipe B-2. Area A is a land area including structures divided by functional use attributes in the urban area, and the area of ​​the unit area is 0.3 square kilometers; the structures are residential quarters, industrial and mining enterprises or institutions or schools or hospitals or shopping malls. , each of the unit area A is provided with a sewage pipeline A-1 and a rainwater pipeline A-2 that communicate with the structure drainage pipeline, the rainwater pipeline A-2 is communicated with the sewage pipeline A-1, and the sewage pipeline A- 1 is communicated with the water inlet end of the first precipitation regulation storage tank C, the first discharge end of the first i...

Embodiment 2

[0109] like Figure 5 As shown, in the present embodiment, the rainwater main pipe B-2 is connected with a rainwater pretreatment system through a branch pipe, and the branch pipe is provided with a downwardly opening weir gate 9, and the downwardly opening weir gate 9 is located in the rainwater pretreatment system. front end of the system.

[0110] The rainwater pretreatment system includes a particle separator 2, a filter 3 and a rainwater treatment module 4 that are connected in series in sequence.

[0111] The control method of this embodiment is that in the residential area, the domestic sewage discharged by the residents and the rainwater collected by the rainwater outlet are both discharged through the rainwater and sewage pipes of the sewage pipe A-1 and the rainwater pipe A-2. The primary rainwater storage tank C performs precise control and collects sewage and primary rainwater that cannot be treated in time by the sewage treatment plant. A second primary rainwate...

Embodiment 3

[0115] like Image 6 As shown, in this embodiment, it includes a plurality of unit areas A and municipal road areas B, and unit area A is a land area including structures divided by functional use attributes in the urban area, and the structures are residential quarters, industrial and mining enterprises, institutions, schools. , a hospital or a shopping mall. Unit area A is provided with sewage pipe A-1 and rainwater pipe A-2, and municipal road area B is provided with sewage main pipe B-1, rainwater main pipe B-2 and municipal rainwater pipe B-3; rainwater pipe A- 2 is connected with the sewage pipe A-1; the end of the sewage main pipe B-1 is connected to the storage tank 11 and the sewage treatment plant 5, and the municipal rainwater pipe B-3 is connected with the rainwater main pipe B-2; The end is connected to the natural water body 6; the end of the sewage pipe A-1 is connected to the water inlet end of the first diversion well 9, and the sewage outlet end and the clea...

Abstract

The invention discloses a non-point pollution control system for a combined sewer system and a control method thereof. The system comprises a trunk sewer, a storm-water sewer and rain and sewage pipes, and also comprises one or more unit areas, and a sewage pipe and a rainwater pipe are disposed in each unit area. Outlets of each sewage pipe and the corresponding rainwater pipe are communicated with an inlet of the corresponding rain and sewage pipe. Outlets of the rain and sewage pipes are connected with an inlet of the trunk sewer, and an outlet of the trunk sewer is provided with a sewage treatment plant. An outlet of the storm-water sewer is communicated with natural water. The non-point pollution control system is characterized in that the trunk sewer is provided with first rainwatertreatment systems, water inlets of the first rainwater treatment systems are communicated with the rain and sewage pipes, and drainage ends of the first rainwater treatment systems are respectively communicated with the trunk sewer and the storm-water sewer. The system and control method are simple in structure and convenient to construct, and efficient treatment of sewage and preliminary rainwater in regions divided by administrative functions in a city can be achieved just by building diversion treatment systems in the limited regions of municipal roads.

Description

technical field [0001] The invention relates to a surface pollution control system and a control method thereof, belonging to the technical field of decentralized source surface pollution control, and in particular to a surface pollution control system and a control method thereof for a combined drainage pipe network system. Background technique [0002] The urban municipal drainage system is mainly divided into a combined drainage system and a split drainage system. The earliest combined drainage system is to mix domestic sewage, industrial waste water and rainwater in the same pipe, and directly discharge it into the nearby water body without any treatment, causing serious pollution to the receiving water body. Almost many old cities at home and abroad have in this way. Now often used is a closed-flow combined drainage system. [0003] The interception and confluence drainage system is basically the same in structure as the traditional confluence drainage system. The dif...
