Description

The governing system and method for the pumping plant being connected to natural water
Technical field
The present invention relates to plumbing technical fields, are specifically related to a kind of governing system of pumping plant being connected to natural water And method.
Background technique
As urbanization process in all parts of the country is accelerated, cities and towns rainwash contamination hazard is increasingly subject to more and more close Note.China still mainly uses two kinds of drainage systems of combined system and separate system at present.The part pipeline of combined system and the rain of separate system Water pipe is all directly to be connected with natural water.But domestic some cities such as Shanghai, Shenzhen, Wuhan etc. are regional due to underground near a river Water level is higher, and the river water level in city is also higher, and urban river water enters in above-mentioned pipeline, so that persistently maintaining in pipeline a certain amount of Water.
It is as follows in the prior art there are two types of the general processing modes of the water of this part:
One, by the lasting water forced-ventilated by pipeline of pumping plant, extraction is discharged into river, but due to level of ground water also compared with Height still has underground water and persistently penetrates into pipeline even if there is pumping plant to take away, so that a certain amount of water is still had in pipeline, And continue pumping plant not only higher cost of drawing water and result in waste of resources, it will also result in the decline of Urban Underground water level;
Two, the water in pipeline is placed on always pipeline, and when rainy, the water in pipeline flows into nature after mixing with rainwater Water body.
But if the water in pipeline is placed in pipeline always, more problems can be faced, especially when pipeline is When the pipeline being directly connected to natural water.Specific problem is as follows:
First, usually there is a certain amount of water in pipeline, after entering pipeline due to sanitary sewage mistake section, this part ponding exists Fermentation is smelly in pipeline, and the water accumulated in the pipeline is changing to sewage, once rainfall, since pipeline is connected to natural water, Sewage inside these pipelines will be directly discharged into natural water, be polluted to natural water.
The second, due to being filled with water in pipeline for a long time, water does not flow again, and duct bottom will accumulate a large amount of deposit, right A large amount of mud but will be deposited in the duct bottom not handled throughout the year, when dropping heavy rain, the deposit and mud of duct bottom are just Rainwater can be mixed and form sewage, natural water (such as river) is discharged to, further natural water is polluted.
Moreover, in existing pumping plant, when rainfall, the water drainage of rainwater pump startup, rainwater pump will be the silt for bottom of pond portion of catchmenting Mud is pumped in river, also be will appear Heisui River and is entered river phenomenon.
Therefore, in level of ground water and the higher city of river water level, how existing pumping plant is transformed and is avoided pollution certainly Right water body is a urgent problem to be solved.

After first rinse, separated in time introduces the water of natural water in pipeline 1, rushes again to pipeline 1 It washes, the flowing water of flushing pipe 1 enters storage pool 2.
At least one is installed in pipeline 1 and intercepts part;
Pipeline 1 is segmented using part is intercepted, the water level for intercepting part upstream rises, and after water level rises to certain altitude, blocks It cuts part to open, rinses the pipeline for intercepting part downstream;
When there are multiple spaced interception parts, since the interception part close to water pump, passes sequentially through and intercept part unlatching The pipeline for intercepting part downstream makes flowing water rinse the pipeline for intercepting part downstream.
Optionally, which includes control system, control system include rainfall gauge, liquidometer and respectively with rainfall gauge, liquid The controller of position meter signal connection,
Rainy day mode further include:
Rainfall threshold value and level threshold are set in controller;
When the rainfall that rainfall gauge monitors is less than rainfall threshold value, controller controls the access between storage pool 2 and pump chamber 3 State is cut-off, and controlling the channel status between natural water and pump chamber 3 is conducting;At this point, the water level of pipeline 1 rises.
When rainfall gauge monitors that rainfall reaches rainfall threshold value, while the liquid level in the storage pool 2 that monitors of liquidometer is high When degree is lower than level threshold, it is conducting that controller, which controls the channel status between storage pool 2 and pump chamber 3, control natural water with Channel status between pump chamber 3 is cut-off.Controller realizes the control that pipeline 1 rinses.
When the rainfall that rainfall gauge monitors reaches rainfall threshold value, while the liquid level in the storage pool 2 that detects of liquidometer When height is higher than level threshold, it is cut-off that controller, which controls the channel status between storage pool 2 and pump chamber 3, controls natural water Pipeline between pump chamber 3 is connected.
Wherein, the peak level of storage pool 2 can be monitored by liquidometer, and storage pool 2 can be set to volume V=V1+V2, V1 accumulates in the water in pipeline when being fine day, V2 is storage volume needed for collecting the first rain of certain millimeter.In practical application In, the volume and highest reserve-water-level of storage pool 2 can be set as the case may be, control storage pool 2 reaches preset highest When reserve-water-level, the rainwater for being mixed with ponding is all collected, and clean rainwater is emitted into natural water 3.
Wherein, controller is connect with flusher signal;
Rinse mode further include: controller controls storage pool 2 and pump chamber 3 according to the working signal of flusher, controller Between channel status be conducting, controlling the channel status between natural water and pump chamber 3 is cut-off.
The system includes the control system with controller, and pump chamber 3 includes that fine day pumps 6 and rainwater pump 7, controller and fine day Pump 6 pumps 7 signals with rainwater and connects;
When fine day, the part ponding in pipeline 1 is discharged to sewage treatment by sewage conduct 1 by controller control fine day pump 6 Factory.
When the rainy day, at rainfall initial stage, the sewage of ponding and rainwater mixing in the pipeline 1 of rain-out is discharged to pump chamber 3, controls Sewage is drained into storage pool 2 by device control rainy day pump processed;
With the continuation of rainfall, the rainwater flowed out through pipeline 1 is emitted into natural water by controller control rainy day pump;
At the end of rainfall, controller control rainy day pump stops working.
Those skilled in the art can carry out various modifications to the embodiment of the present invention and modification, if these modifications and change For type within the scope of the claims in the present invention and its equivalent technologies, then these modifications and variations are also in protection scope of the present invention Within.
