Description
Technical field
The utility model relates to field of waste water treatment, more specifically to a kind of desulfurizing waste water processing device.
Background technique
In recent years, China payes attention to environmental protection further, thermal power generation unit is equipped with flue gas desulfurization device to guarantee cigarette
The qualified discharge of gas.Most of thermal power plant has desulfuration efficiency height, technology maturation etc. using wet desulphurization device, this method
Advantage, but desulfurization wastewater can be discharged in sweetening process, desulfurization wastewater contains a large amount of dirt at faintly acid (PH 4-6)
Object, such as heavy metal ion, inorganic ion, suspended matter etc. are contaminated, therefore, it should effectively be located before desulfurization wastewater discharge
Reason.
Desulfurization wastewater treatment system generally by wastewater collection pond, three headers, clarifying basin, clear water reserviors, sludge treatment equipment and
Chemicals dosing plant composition.Wherein three headers (being made of neutralization case, reaction chamber, flocculation tanks) are the cores in desulfurization wastewater treatment system
Equipment, after the processing of three headers, waste water enters clarifying basin, carries out mud-water separation.After waste water enters neutralization case, passes through and stone is added
Grey cream adjusts pH value, makes waste water pH value 9-10, and most of heavy metal ion forms hydroxide precipitating at this time.It does not precipitate part
Heavy metal ion enters reaction chamber with waste water, by the way that organic sulfur solution is added into reaction chamber, makes the part heavy metal ion shape
At slightly soluble sediment.Flocculant is added simultaneously, makes the flocculate of suspended matter and each sediment formation larger particles in waste water.Then
Waste water enters flocculation tanks, makes the flocculate accelerated sedimentation of above-mentioned formation by the way that flocculation aid is added.Since three headers carry out waste water
The mode of chemical dosing and contact mud is carried out continuously processing, and the waste strength after handling is higher, when waste water treatment system stops
When only running, the waste water of high concentration slowly not toward clarification concentrator overflow, flooding velocity is slower and slower, pipeline again put down length, give up
For a long time solidification phenomenon occurs for the generation precipitating in pipeline of water slowly, reduces overflow pipe flow area.When crossing one section
Between put into operation again waste water when three header flooding velocitys due to flow area reduce and it is slack-off, finally result in the waste water stream into three headers
Amount is greater than excess flow, gradually becomes full to neutralization case again from flocculation tanks to reaction chamber, finally runs and emits with box top generation in, in
Showing it is not very accurate with case liquidometer, prison disk personnel can not judge whether that overflow occurs, patrol officer can only be depended on, once occur
Race, which emits, increases workload, hinders the normal operation of waste water system.
For the higher caused defect of existing desulfurization wastewater concentration, existing related art scheme is disclosed, such as number of patent application:
201520473946X, the applying date: on November 04th, 2015, invention and created name are as follows: a kind of desulfurization wastewater treatment system, the Shen
Please case disclose a kind of desulfurization wastewater treatment system, including desulfurization wastewater preformed precipitate device and three headers, desulfurization wastewater preformed precipitate
It is provided with the pulse suspension system connecting with desulphurization system in device, is provided on desulfurization wastewater preformed precipitate device several with three
The supernatant discharge outlet of case connection.The slurries for being derived from desulphurization system are discharged to desulfurization by the desulfurization wastewater treatment system of this application
In waste water preformed precipitate device, by natural sedimentation of the slurries in desulfurization wastewater preformed precipitate device, then the clear liquid on upper layer is led to
It crosses supernatant discharge outlet to be discharged into three headers, the higher deposition slurries of desulfurization wastewater preformed precipitate bottom of device solid content pass through
Pulse suspension system is returned to absorption tower, thus efficiently solve the problems, such as that desulfurization wastewater solid content is high, this application middle arteries
Suspension system higher cost is rushed, there is the space advanced optimized.
In conclusion how to overcome the problems, such as that existing desulfurization wastewater solidifies caused three headers race in overflow pipe precipitating and emits, it is
The technical problem of urgent need to resolve in the prior art.
The information disclosed in the background technology section is intended only to increase the understanding to general background of the invention, without answering
When being considered as recognizing or imply that the information constitutes the prior art already known to those of ordinary skill in the art in any form.
