Grain, colloid, macromolecular protein, virion, the charged particles such as cell be oriented under the action of electric field force it is mobile, touch
It hits, therefore causes charged particle electric double layer by compression and take off surely, and then flocculate for big partial size wadding body and precipitate rapidly.Currently,
The common electric flocculation reactor of field of waste water treatment determines pole formula to be horizontal, and is relatively mostly to join electric flocculation and other water treatment facilities
Close application, such as spiral-flow type clarifier etc..There are many defects with spiral-flow type clarifier process integration system for electric flocculation, firstly,
The pattern electric flocculation reactor is not suitable for handling high suspended matter content waste water, and have easily blocking, easily occur short stream, cost it is high and
The defects of equipment installation is complicated；Secondly, common spiral-flow type clarifier clarifying efficiency is low, outlet effect is bad, is only applicable to coal slime
The relatively simple waste water treatment system of the water quality such as water.
Vertical cabinet formula electric flocculation device has the characteristics that reliable for operation, stable effluent quality and operation and maintenance are easy, and
Processing suitable for all kinds of high-turbidity waters.Decarbonization process then has preferable removal hardness, basicity and efficiently clear at a slow speed
Effect is to utilize to add the medicines such as flocculating agent, flocculation aid, lime or sodium carbonate it includes coagulating basin, flocculation basin and inclined plate clarifying basin
Agent makes the impurity such as the colloid in raw water contact with each other, adsorb, settle, to reach the water purification facilities of softening and mud-water separation.It is solidifying
Poly- pond is under specific blender speed conditions, it can be achieved that flocculating agent is quickly uniformly mixed.Guide shell, high reflux ratio are set in flocculation basin
With lower sludge circulation than lower, it can be achieved that ideal coagulation effect.Inclined plate clarifying basin is equipped with sludge condensation area, inclined plate area, clear water
The features such as area has mud-water separation high-efficient, and anti impulsion load ability is strong, and occupied area is small.
Summary of the invention
The object of the present invention is to provide a kind of electric flocculation-decarburization combined water treatment devices at a slow speed, by electric flocculation reaction unit
After organic combination, with coagulating basin, flocculation basin and inclined plate clarifying basin is integrated builds jointly, treatment effect not only effectively ensure that, but also save
Construction area, reduces project cost.
To achieve the above object, the present invention adopts the following technical scheme that:

Decarbonization process equipment is made of coagulating basin, flocculation basin and inclined-plate clarifying basin three parts at a slow speed；Inclined-plate clarifying basin includes
Plug-flow area, preliminary sedimentation area, inclined plate area and sludge condensation area；Wherein, sodium hydroxide chemicals dosing plant, electric flocculation are provided on coagulating basin
Reaction tank is connected with coagulating basin, and sodium carbonate or calcium hydroxide chemicals dosing plant, flocculation basin and coagulating basin bottom are provided on flocculation basin
Portion is connected；Flocculation basin is connected with plug-flow area, and plug-flow area is connected with preliminary sedimentation area, and preliminary sedimentation area is connected with inclined plate area, inclined plate area bottom
Sludge condensation area is arranged in portion.
A further improvement of the present invention lies in that electric flocculation reaction unit uses vertical cabinet formula electric flocculation reaction unit.
A further improvement of the present invention lies in that welding the branch for fixing electric flocculation reaction unit in electric flocculation reaction tank
Frame.
A further improvement of the present invention lies in that electric flocculation reaction bottom of pond portion is provided with aeration antipriming pipe, aeration antipriming pipe with
The one end for being aerated main pipe is connected, and the other end for being aerated main pipe is connected with compressed air reservoir.
A further improvement of the present invention lies in that pneumatic door opening-closing and manual ball valve is arranged in aeration main pipe.
A further improvement of the present invention lies in that being provided with coagulating basin blender in coagulating basin, coagulating basin blender is using double
Layer paddle agitator arm.
A further improvement of the present invention lies in that guide shell and flocculation basin blender are provided in flocculation basin, flocculation basin stirring
Device promotes agitator arm using single layer push type.
A further improvement of the present invention lies in that being equipped with hand operated gate valve at the top of electric flocculation reaction tank.
A further improvement of the present invention lies in that being provided with mud scraper in inclined plate area.
A further improvement of the present invention lies in that sludge condensation area is connected with flocculation basin.
Compared with prior art, the invention has the benefit that
