Technical Field
The invention relates to the technical field of urban drainage, in particular to a municipal engineering rain and sewage diversion system.
Background
In recent years, with the development of economy in China and the enhancement of environmental awareness of residents, the demand for water is increasing, and in order to reasonably utilize various water resources and avoid waste and pollution of the water resources, China begins to implement drainage modes of rainwater and domestic sewage by using one drainage pipeline respectively. Domestic sewage mainly comes from wastewater produced in daily life and diet living of people, is discharged through a sewer pipeline or a sewage pipeline and finally flows into a sewage treatment plant for treatment. For rainwater, the initial rain (rainwater in the early stage of rainfall) carries more pollutants, such as heavy metal substances carried by a washed road surface, pollutants carried from the atmosphere and the like, if the pollutants are directly discharged into a river water body, toxic and harmful substances such as heavy metals and the like are continuously enriched by organisms, so that the biological environment of the water body is greatly influenced, and the harmful effects on the health of urban residents are also caused, so that the sewage generated by the washing of the initial rain on the ground cannot be directly discharged into a river channel. When the ground is washed cleanly by rainwater, the rainwater is slightly polluted, and can be directly discharged into urban inland rivers after being shunted, and can be used as natural landscape water after being naturally precipitated and can also be used as urban municipal water for spraying roads, so that the rainwater flows into rivers after being purified and buffered, and the use benefit of surface water can be improved; meanwhile, polluted rainwater is discharged into a sewage pipe and is treated by a sewage treatment plant, so that sewage is recycled.
However, the existing rainwater drainage mode can cause that a sewage treatment plant cannot timely judge the condition that rainwater is polluted, possibly causing that the sewage treatment plant excessively treats rainwater or fails to treat all polluted rainwater, causing the condition that the sewage treatment plant runs under high load or treats insufficient sewage, and when the sewage treatment plant cannot treat all polluted rainwater, the polluted rainwater can cause water pollution when being discharged into a river.
Therefore, there is a need for a new rain and sewage separation system.

A control unit 12 is arranged at the outlet 14 of the effluent collection well and is capable of controlling the flow of effluent out of the outlet 14. The sewage flow at the sewage collection well inlet 13 is a first flow, i.e. the sewage flow flowing into the sewage collection well 3 through the inlet 13 is a first flow. The sewage flow at the outlet 14 of the sewage collection well is a second flow, i.e. the sewage flow out through the outlet 14 to the sewer piping 7 is a second flow. The first flow rate is much greater than the second flow rate.
For the preset area, the polluted initial rain volume can be calculated according to the catchment area of the area, and the volume of the sewage collecting well 3 is designed by calculating the polluted initial rain volume. Become sewage and flow into in the sewage collecting well 3 along rainwater pipeline 1 after the rain erodees ground just, because the sewage flow that flows into sewage collecting well 3 is greater than the sewage flow that flows out sewage collecting well 3, the sewage volume that flows into sewage collecting well 3 promptly is greater than the sewage volume that flows out sewage collecting well 3, make the sewage of keeping in sewage collecting well 3 more and more, reach the preset scope when the sewage volume, when sewage surface of water W reaches the preset position, switch part 11 closes the import 13 at sewage collecting well top, subsequent rainwater is direct to flow away through rainwater pipeline 1, sewage in the sewage collecting well 3 slowly flows out sewage pipeline 7.

In this embodiment, the switch member 11 may be a float ball which floats up to seal the inlet 13 of the sewage collecting well when the sewage level reaches a predetermined range. The predetermined range may be a specific value or a range of values. The switch member 11 may also include a driving portion and a blocking portion, and when the water level in the wastewater collection well 3 reaches a predetermined range, a mechanical signal or an electrical signal is generated, and the driving portion receives the signal and drives the blocking portion to close the inlet 13. The control unit 12 is able to control the sewage flow at the outlet 14 of the sewage collection well to be smaller than the sewage flow entering the inlet 13, for example by means of a gap in the movable part itself or between the movable part and the wall of the sewage collection well for the sewage to flow out to the sewage pipe 7; the control unit 12 may also control the sewage flow as a valve-like structure.

As shown in fig. 1 and 2, a rain and sewage separating system includes a rainwater pipe 1, a sewage pipe 7, and a rain and sewage separating apparatus. The storm water conduit 1 and the sewage conduit 7 are arranged horizontally. The rain and sewage separating device comprises a sewage collecting well 3, a switch component 11 and a control component 12. The sewage collecting well 3 is vertically arranged. The top of the sewage collecting well 3 has an inlet 13, which inlet 13 is fixed to and communicates with the storm water pipe 1, and the bottom of the sewage collecting well 3 has an outlet 14, which outlet 14 is fixed to and communicates with the sewer 7.

The rain and sewage separation system is vertically arranged, the upper part is a rain water pipeline 1, the middle part is a sewage collecting well 3, and the lower part is a sewage pipeline 7.
The floater 11 is freely placed in the inside of sewage collecting well 3, and its density is less than sewage, and its diameter is less than normal round mouth diameter and is greater than the minimum bore of gradual change shrink mouth, guarantees to float under the effect of sewage and then closes the import 13 of sewage collecting well for discharge most rainwater along rainwater pipeline 1 when lasting the rainfall, and can freely fall back under the anhydrous condition. The inlet 13 of the sewage collecting well can be provided with a P-type water seal (P-type water seal) 2, and the floating ball 11 can be contacted with the P-type water seal 2 when floating upwards to close the inlet 13.
The fixed part 8 may be an arc-shaped plate with a larger area, the movable part 6 may be an arc-shaped plate with a smaller area, and the fixed part 8 and the movable part 6 may be connected by a hinge 10 to form a circular plate, the periphery of which may match with the wall 16 of the sewage collecting well. The fixed part 8 is fixed on the wall 16 of the sewage collecting well 3, and the movable part 6 can be turned over up and down in a certain angle range relative to the fixed part 8.
The fixed part 8 and the movable part 6 are obliquely arranged at the outlet 14 of the sewage collecting well. The fixed part 8 in the upstream direction is welded with the wall 16 of the sewage collecting well to ensure that the fixed part is fixed obliquely downwards and is fixedly connected with the wall 16 of the sewage collecting well by the reinforcing part 9, the movable part 6 is prevented from falling due to water pressure, and the movable part is supported. The movable portion 6 is provided with a wire rope 4 and a spring rope 5 as a return portion. The steel wire rope 4 is obliquely arranged, the top of the steel wire rope is fixed with the well wall 16 of the sewage collecting well 3, and the bottom of the steel wire rope is fixed with the movable part 6. The spring rope 5 is obliquely arranged, the top of the spring rope is connected with the wall 16 of the sewage collecting well 3, and the bottom of the spring rope is connected with the movable part 6.
