Description
Technical Field
The invention relates to the technical field of sewage treatment, in particular to an overflow pollution control and backflow prevention system.
Background
By now, the water environment remediation work all over the country has achieved remarkable results. For places which are difficult to realize distribution of rain and sewage or mixed misconnection transformation in a short period, such as old cities, rural areas and the like, in order to achieve the purposes of water environment remediation and sewage treatment physique synergism, a tail-end sewage interception mode is usually adopted. Due to the reasons that the intercepting well is unreasonable in design, the backflow prevention device fails and the like, a large amount of rainwater is intercepted in rainy days, so that sewage pipes in partial areas run at high water levels, the inflow concentration of a sewage plant is low, and the stable running and efficiency improvement of the sewage plant are affected.
In order to solve the problem of excessive intercepting sewage discharged to a sewage plant in rainy days, intercepting wells gradually develop novel adjustable weirs (lower opening type adjusting weirs and rotary type adjusting weirs) driven by electric control or hydraulic control from the past simple fixed weirs (groove type and weir type), but the intercepting wells still cannot accurately adjust and control the intercepting amount. Meanwhile, due to the limitation of the height of a drainage pipe network, the mode of intercepting by gravity also limits the application of the novel adjustable weir intercepting well in certain scenes. In addition, the flap valve or the duckbill valve for preventing the river water from flowing backwards also has the condition that the flap valve or the duckbill valve cannot be completely closed, so that a large amount of river water enters a sewage intercepting pipe network, and the water inlet concentration of a sewage plant is reduced.
Therefore, those skilled in the art are dedicated to develop an overflow pollution control and anti-backflow system, which not only can accurately control the amount of sewage interception and avoid the failure of flap valve or duckbill valve anti-backflow function, but also is easy to implement, low in cost and convenient to manage, thereby realizing the improvement of water environment quality and the improvement of sewage treatment efficiency.

Detailed Description
The conception, the specific structure and the technical effects of the present invention will be further described with reference to the accompanying drawings to fully understand the objects, the features and the effects of the present invention.
Example (b):
as shown in fig. 1-2, an overflow pollution control and backflow prevention system includes a water inlet pipe 1, a grid well 2, a first water outlet pipe 4, a sewage interception well 5, a fifth water outlet pipe 11, and a backflow prevention device 12;
the water inlet pipe 1 is arranged at one side of the grid well 2, the grid well 2 is communicated with the sewage intercepting well 5 through the first water outlet pipe 4, the fifth water outlet pipe 11 is arranged at one side of the sewage intercepting well 5, the backflow preventer 12 is arranged in the fifth water outlet pipe 11, and the sewage discharging device communicated with a current sewage system is arranged in the sewage intercepting well 5;
the sewage discharging device comprises a first sewage pump 6 and a second sewage pump 7 with different starting water levels, the first sewage pump 6 and the second sewage pump 7 are respectively communicated with a second water outlet pipe 8, each second water outlet pipe 8 is respectively communicated with a fourth water outlet pipe 10 through a third water outlet pipe 9, and the fourth water outlet pipe 10 is communicated with the current sewage system.
Specifically, the grille well 2 is provided with an artificial grille 3 which can intercept the floating objects in the sewage, ensure the stable operation of the first sewage pump and the second sewage pump and avoid the floating objects from entering the river channel.
Specifically, the intercepting well 5 is provided with a first sewage pump 6 and a second sewage pump 7, and can lift the intercepted sewage to a current sewage system.
Specifically, the fifth water outlet pipe 11 is provided with a built-in backflow preventer 12, so that the backflow of river water can be effectively avoided.
Specifically, the backflow preventer 12 is made of a special material and is corrosion resistant.
The working principle of the invention is as follows:
in dry days and early rainwater periods, sewage firstly enters the grid well 2 through the water inlet pipe 1, is filtered by the artificial grid 3 in the grid well 2 and then flows into the intercepting well 5 through the first water outlet pipe 4; when the water level in the intercepting well 5 reaches a first pump starting water level H1, the intercepting well 5 starts a first sewage pump 6 to lift sewage, when the water level in the intercepting well 5 reaches a second pump starting water level H2, the intercepting well 5 starts a second sewage pump 7 to lift sewage, and the lifted sewage is finally discharged to a current sewage system through a second water outlet pipe 8, a third water outlet pipe 9 and a fourth water outlet pipe 10; at this time, the built-in backflow preventer 12 is in a closed state to prevent the river water from flowing backward.
Along with the gradual increase of rainfall, the lifting capacity of the first sewage pump 6 and the second sewage pump 7 reaches the maximum, and the combined sewage overflows to a river channel through a fifth water outlet pipe 11; at this time, the built-in backflow preventer 12 is in an open state.
After the rainfall is finished, the operation modes of the first sewage pump 6, the second sewage pump 6 and the backflow preventer 12 are restored to the dry day mode.
