Detailed description of the invention
For the clearer technical solution for illustrating the utility model embodiment or the prior art, below will to embodiment or
Attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
Some embodiments of the utility model, for those of ordinary skill in the art, without creative efforts,
It is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of the sewage disposal system in power plant provided by the embodiment of the utility model；
Fig. 2 is the structural schematic diagram of level-one recovery pond provided by the embodiment of the utility model.
Specific embodiment
In order to make those skilled in the art better understand the scheme of the utility model, with reference to the accompanying drawing and specific implementation
The utility model is described in further detail for mode.Obviously, described embodiment is only the utility model a part
Embodiment, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not doing
Every other embodiment obtained under the premise of creative work out, fall within the protection scope of the utility model.
As shown in FIG. 1, FIG. 1 is the structural representations of the sewage disposal system in power plant provided by the embodiment of the utility model
Figure, the sewage disposal system may include:
The level-one recovery pond being connected with plant area's bilge discharge pipe road；Secondary recovery pond；By the sewage in level-one recovery pond
The water pump being pumped into secondary recovery pond；The sewerage disposing device being connected with secondary recovery pond；
Wherein, the level-one recovery pond is for depositing the sewage in the bilge discharge pipe road；
The volume in the secondary recovery pond is greater than the volume of the level-one recovery pond, for storing from the level-one recovery pond
The sewage of middle discharge；
The sewerage disposing device is for handling the sewage being discharged in the secondary recovery pond, after to processing
Sewage recycled.
It should be noted that the sewage being discharged in bilge discharge pipe road in the present embodiment is the total outfall of full plant area
The sewage of discharge after being discharged into level-one recovery pond by bilge discharge pipe road, a degree of purification is carried out in level-one recovery pond, is removed
The deposits such as partial particulate, cinder in decontaminated water；Purified sewage will be deposited by water pump again and be discharged into secondary recovery pond, two
The volume of grade recovery pond is relatively large, and effect is reservoir because from the water that level-one recovery pond is discharged be to pass through in from water
Reason device is handled, and sewerage disposing device is limited to the ability of sewage treatment, and the sewage being discharged into level-one recovery pond
Amount be bad control, therefore secondary recovery pond is set between level-one recovery pond and sewerage disposing device, for temporary
Sewage is stored, the pressure that sewerage disposing device carries out sewage treatment is reduced；Sewage is after the processing of sewerage disposing device, it can
It comes into operation as middle water.Because of middle water and undrinkable water, the requirement to water quality is relatively low, also just reduces to sewage treatment
Difficulty, reduce the cost to sewage treatment, and sewage disposal system provided in the present embodiment, be total to full plant area
Outfall discharge sewage handled, continue to come into operation after processing, do not need to be discharged into external environment, very
Positive has accomplished zero-emission no pollution.
Based on above-mentioned any embodiment, in the another specific embodiment of the utility model, as shown in Fig. 2, Fig. 2 is this reality
With the structural schematic diagram for the level-one recovery pond that new embodiment provides；The level-one recovery pond can also include:
Spillway basin 2 is additionally provided with inside level-one recovery pond 1, the Sidewall Height of spillway basin 2 is less than the side wall of level-one recovery pond 1
Highly；The discharge outlet drained outward is provided on the side wall of spillway basin 2.
Because in addition to there is the sewage after various uses to be discharged in total bilge discharge pipe road in plant area, while further including factory
The discharge of rainwater in area.
In rainy weather, if on-site amount of rainfall is larger, it is discharged into level-one recovery pond and secondary recovery water amount is excessive,
And the processing of sewerage disposing device is not in time, and it is insufficient to will lead to secondary recovery pond storage capacity.
For this purpose, spillway basin is arranged inside level-one recovery pond, when the water level in level-one recovery pond is excessively high, can lead to automatically
It crosses and a part is discharged in spillway basin.Because the sewage of discharge is mostly rainwater, water quality comparatively will not be too
Difference is directly discharged in environment, can also reach sewage drainage standard.
Optionally, as shown in Fig. 2, the top side wall of spillway basin 2 is provided with strainer 3.
Because the water in spillway basin 2 is to need to be emitted into environment, in order to avoid in level-one recovery pond some particles or
The objects such as cinder are discharged away, and strainer 3 can will be arranged on spillway basin 2.
Optionally, deslagging device is additionally provided in level-one recovery pond.
Because level-one recycling bottom of pond portion can mainly deposit some cinders, particle even mud, in order to avoid water pump is being incited somebody to action
When water in level-one recovery pond is pumped into secondary recovery pond, the sediment of level-one recycling bottom of pond portion is also extracted to secondary recovery
Chi Zhong can recycle bottom of pond portion in level-one and deslagging device is arranged, which specifically may is that
Close to the mesh device of level-one recycling bottom of pond portion, and it is arranged in bionical between mesh device and level-one recovery pond
Water plant.So sediment once penetrate network and free water plant be deposited on level-one recycling bottom of pond portion after, due to bionical water
The blocking of grass, it will be able to be largely avoided it and float again since water flow is sprung up, improve and be discharged into secondary recovery pond
Cleannes；For being deposited on the sediment of level-one recycling bottom of pond portion, periodically handle.
Optionally, in the another specific embodiment of the utility model, the sewerage disposing device can be wrapped further
It includes:
Sedimentation basin and the chemicals dosing plant being arranged in sedimentation basin.
Sewage handled, inevitably need to use chemical agent or biological agent, after sewage treatment, no
It is evitable to generate reactant, it can guarantee the cleaning of sedimentation basin water quality at the middle and upper levels after reactant precipitating.
Optionally, which may include degrease device, desulfurizing device, deodorization device and sterilization specifically
Device.
Deodorization device and sterilizing unit can use device of the bio-pharmaceutical device for example containing deodorizing sterilizing microorganism, or
Person's chemicals device, such as chemical deodorizing reagent, 84 disinfectants etc..
Optionally, sewerage disposing device is connected with circulating cooling pond, and the waste water for obtaining sewage treatment drains into
In circulating cooling pond, to be cooled down for power generator turbine.
In view of the water quality of the bottom in the sedimentation basin of sewerage disposing device is relatively poor, it can not reach middle water use and want
It asks, it therefore, can be by the water of the part as being discharged in waste water therefrom water treatment facilities.
And power generator turbine recirculated cooling water is low to water quality requirement, therefore, the effluent part can be used as power generator turbine
Cooling water, improve plant area's waste water utilization rate.
Each embodiment in this specification is described in a progressive manner, the highlights of each of the examples are with it is other
The difference of embodiment, same or similar part may refer to each other between each embodiment.For being filled disclosed in embodiment
For setting, since it is corresponded to the methods disclosed in the examples, so being described relatively simple, related place is referring to method part
Explanation.
