Description
Technical Field
The utility model belongs to the technical field of black and odorous river channel is administered, belong to the pumping station and put river pollution control's facility, specifically indicate a multiple-effect multiplication regulation pond.
Background
With the rapid development of cities and the increasing population density, the problem of river water environment is increasingly highlighted, and most of urban river channels are developed into black and odorous river channels. The problem of the black and odorous river channel seriously affects the life quality of surrounding residents and the urban image. The black and odorous cause of the river channel is that the external source pollution caused by directly connecting pollutants into the river is the main cause of the black and odorous river channel external source pollution except that the ecological system of the river channel is damaged due to urban construction.
In the existing river pollution control measures, the method mainly comprises initial rainwater source control, pipeline rainwater and sewage mixed connection transformation, drainage pipeline dredging, pump station sewage interception, sewage ex-situ treatment and the like, but because each technical means has respective limitation, the problem of river channel blackness and odor is difficult to solve in a short time.
The initial rainwater source control technology is used for reducing pollutants in initial rainfall runoff by utilizing the source control technology, preventing the pollutants from entering municipal drainage pipelines and finally discharging the rainwater along with a pump station to enter a received river channel. However, the initial rainfall runoff pollution belongs to non-point source pollution, the related area is large, and the traditional source control technology cannot cover most of areas in a short period, so that the initial rainfall runoff pollution cannot be effectively controlled.
Drainage pipe rain and sewage mixed connection reconstruction means that through engineering reconstruction, mixed connection points in a municipal pump station are eliminated, sewage is prevented from entering a rainwater system, and pollutants discharged along with the pump station into a river channel are reduced. However, in the municipal drainage system, the mixed connection points are numerous, the project is huge in one-by-one investigation and reconstruction, the period is long, and pollutants caused by mixed connection of pipelines cannot be effectively controlled to enter the river in the near term.
The drainage pipeline dredging is to regularly clean sediments in the pipeline, so that pollutants are prevented from entering a river channel along with a pump station after a large amount of rainwater washes sediments at the bottom of the pipeline when rainfall occurs. However, because social resources are limited, the dredging period of the pipeline is long, the sediment amount in the main pipe of the drainage system is large and difficult to clean, and the traditional drainage pipeline dredging technology has a limited effect on controlling river discharge pollution of a pump station.
The pump station sewage interception technology is characterized in that a sewage interception facility is arranged in a drainage pump station and is used for intercepting sewage mixed and connected in dry days, initial rainwater in rainy days and the like and preventing pollutants from entering a river channel along with the pump station when the pollutants are discharged into the river channel. However, the scale of the sewage interception pump is far smaller than that of the rainwater pump, and the scale of the sewage interception pump of the rainwater pump station is even one tenth of that of the rainwater pump. When a rainfall event occurs, the sewage interception pump cannot discharge a large amount of rainwater doped with pollutants into a sewage system in a rainy day, and a rainwater pump must be started to discharge the rainwater into the river, so that the pollutants enter a water body.
The sewage heterotopic treatment device is characterized in that a small sewage treatment system is arranged in or around a municipal pump station to treat sewage in a front pool of the pump station and initial rainwater in rainy days on line. However, the ectopic treatment device has a limited scale and cannot treat a large amount of runoff generated in rainy days and pollutants generated by flushing the pipeline of a drainage system in a short time.
The pump station river-discharging control technology applied at the present stage has the limitations of long construction period, large investment, short-term effect failure and the like. In addition, a regulation and storage pond is arranged in the pump station of a part of drainage pump stations, is connected with a pump station forebay in parallel and is used for collecting initial rainwater and reducing rainwater runoff peaks. At the present stage, however, many drainage systems are in a high water level operation mode, the pipe diameter of a main pipe of the system is large, the flow velocity of drought sewage in the pipeline is low, pollutants are easy to deposit in the pipe, and sewage with low concentration enters a pump station forebay. When a rainfall event occurs, after the water level in the forebay rises and the regulation and storage tank is opened, the concentration of pollutants in rainwater entering the regulation and storage tank is lower, and the regulation and storage tank is lower in the control efficiency of initial rainwater. A common storage tank needs to be emptied by using an emptying pump, so that the energy consumption is high. The buried depth of the storage regulation pool can reach more than 20m underground, the engineering investment is high, the cleaning and maintenance cost is high, and the engineering benefit is not good.
Therefore, the utility model relates to a multiple-effect multiplication regulation pond is applied to in the municipal pump station, can effectively control the pump station and put the river pollution, reduces into the river pollutant, is the necessary means that realizes that black and odorous river course is controlled for a long time clearly.
