Description

Be applicable to the integrated vertical sedimentation tank of processing of stone slag field high-turbidity water processing
[technical field]
The utility model relates to sewage disposal device, is specifically related to a kind of integrated vertical sedimentation tank that is applicable to the high-turbidity water processing of processing of stone slag field.
[background technology]
The fast development of China's economy has advanced the fast development of stone industries, and a collection of big and small stone material industry cluster or stone material Industrial Area, industry town have appearred in the whole nation.Stone slab producing process need use a large amount of cooling waters, owing to containing cooling agent in cooling water, for saving production cost and reducing the pollution that discharge causes, production technology is normally by the reuse after sedimentation basin repeatedly precipitates of used cooling water, and the rock ballast that precipitation the produces outer slag field landfill of transporting to again.The common addressing in slag field, in remote mountain area, is conducive to the landfill of building a dam like this, reduces processing cost.While outward transport due to rock ballast, just contain a certain proportion of cooling waste water, add while being flowed through in surface, slag field in rainfall and can produce a large amount of high-turbidity waters, turbidity can reach 20000~30000mg/L.If the sewage that slag field produces is not processed and let things run their course, will environment be caused to serious pollution.During due to processing of stone, for reducing saw blade loss, in cooling water, can add " cooling agent ", in the waste water that therefore slag field produces, also contain coolant composition.Conventionally, the Main Ingredients and Appearance of cooling agent is: Resin Acid and saponified, unrighted acid thereof and saponified etc., and such material has very strong chelating complexing power, the small particulate in stone flour can be fixed, can maintain in a long time colloidal state, and do not settled down.Slag field wastewater treatment at present normally adopts the mode of the multi stage precipitation of simply building a dam, weak effect, and dam or row's contamination accident steathily often occur overflowing rainy season.
Conventionally adopt at present the technique of " just heavy-coagulation-precipitation " to process for high-turbidity water.But the high-turbidity water of processing of stone slag field has the advantages that to be difficult to precipitation containing cooling agent emulsification, tradition " coagulation-rectangular sedimentation tank precipitation " technique, not only dosage of PAC is large, and the little difficult precipitation of alumina blossom particles forming, require sedimentation basin hydraulic detention time long, sedimentation basin floor space is large.And the common addressing in slag field is in remote mountain area, be difficult to find large-area level land to build sedimentation basin, therefore traditional handicraft is difficult to carry out in mountain area.
In view of this, the inventor, for the defect further investigation of prior art, has this case to produce then.
[summary of the invention]
Technical problem to be solved in the utility model is to provide a kind of integrated vertical sedimentation tank that is applicable to the high-turbidity water processing of processing of stone slag field.
The utility model is achieved in that
Be applicable to the integrated vertical sedimentation tank of processing of stone slag field high-turbidity water processing, comprise superposed tubular adsorption precipitation district, be positioned at the taper sludge hopper of bottom;
Described sludge hopper bottom is provided with discharge pipeline;
On the outer wall of described settling zone, be provided with water inlet pipe and outlet pipe, inwall is provided with downflow weir;
Be provided with at middle part, described settling zone the vertical central tube being connected with described water inlet pipe; Be provided with umbrella shape reflecting plate in described central tube lower end;
Described water inlet pipe is divided into the horizontal component pipeline that is positioned at the vertical portion pipeline of outside, described settling zone, is connected with described central tube; The central shaft of the horizontal component pipeline of described water inlet pipe is positioned in the tangential direction of circular cross section of described central tube.
Further, in the vertical portion pipeline of described water inlet pipe, be provided with flap.
Further, below settling zone, on the pool wall of part, be provided with observation window.
The utility model has the advantage of: the utility model is combined in vertical sedimentation tank integrated flocculation process by setting up the eddy flow granulation of tangentially intaking of flap and central tube in inlet channel, reduce flocculation basin floor space, and vertical sedimentation tank floor space is little, solve the problem that mountain area is difficult to find large area level land, in addition, this integrated improvement vertical sedimentation tank can be prefabricated in factory, solves the large problem of mountain construction difficulty; Compare with traditional vertical sedimentation tank, this integrated improvement vertical sedimentation tank is loaded by reasonable control surface and is improved settling zone height and forms body refuse suspension filter layer, the suction-operated of performance body refuse superposed layer, solve processing of stone slag field waste water because be difficult for the problem of precipitation containing cooling agent emulsification suspended particulate, the input of Treatment of Sludge facility had both been reduced in the sludge backflow slag field that this treatment process produces, and mud contains the precipitation that coagulant backflow slag field is conducive to sewage in slag field control pond.
[accompanying drawing explanation]
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the utility model structural representation.
Fig. 2 is the A-A cutaway view of Fig. 1.
[specific embodiment]
As depicted in figs. 1 and 2, be applicable to the integrated vertical sedimentation tank of processing of stone slag field high-turbidity water processing, comprise superposed tubular adsorption precipitation district 1, be positioned at the taper sludge hopper 2 of bottom;
Described sludge hopper 2 bottoms are provided with discharge pipeline 8;
On the outer wall of described settling zone 1, be provided with water inlet pipe 3 and outlet pipe 4, inwall are provided with downflow weir 9;
