The processing mechanism of coagulating sedimentation separator of the present invention:
A, coagulation
Colloid pollution thing in the water is difficult to natural sedimentation and separates because the effect of ξDian Wei forms stabilising system, need add medicament and improve.This coagulating sedimentation separator is through adding the counter ion coagulant, electrically neutralizes with colloid pollution deposits yields in the water, reduces ξDian Wei; Compression double electric layer, and then take off surely, simultaneously; Coagulant has linear structure through hydrolysis and the formed high polymer of polycondensation reaction; With the strong adsorption bridging effect of colloid pollution deposits yields in the water, form big floc particle and sink, be beneficial to deposition.Coagulation comprises and mixing and two stages of reaction; The effect that mixes is to make medicament to be diffused into equably rapidly in the water to create good hydrolysis and polymerizing condition; Meanwhile elimination of colloid stability is accomplished immediately and is condensed by the Brownian movement and the turbulent flow of particle; The waterpower release 8 that this coagulating sedimentation separator utilizes water inlet pipe 1 lower end to connect is controlled fine completion mixed process in central cylinder 6 with the subtend setting and the pressure of the perforate direction of first doser 13.Mixed current are flowed by central cylinder 6 from bottom to top, overflow central cylinder 6 and get into housings 5 middle parts, the speed entering stage of reaction that slows down successively.In addition, because the adding of flocculation aid, regulate or improved coagulation condition (like pH etc.), improve flco structure (as: high molecular strong adsorption bridging action etc.), coagulation effect is further improved.
B, precipitation
This coagulating sedimentation separator is similar to vertical sedimentation basin, and the flco that above-mentioned coagulation produces gathers bigger and bigger at housing 5 middle parts, and speed is sunken to the centrum part of housing 5 bottoms more and more sooner, forms mud, and clear water then gets into top, accomplishes mud-water separation.
C, filtration
The filtrate wall 3 of this coagulating sedimentation separator setting has tiny space, has the mechanical retention filtration.Effluent stream through the time, filtrate wall 3 is trapped in the effluent trough outside in large quantities with the fine particle that does not precipitate in the water, forms bulky grain again and gets into the settling zone, clear water then sees through filtrate wall 3 and gets in the effluent troughs 4.
D, suction-operated
The filtrate wall 3 of this coagulating sedimentation separator setting is to be composited by high-density fiber and active carbon, and active carbon is good adsorbent, because active carbon has bigger porosity and specific area, can adsorb the suitable molecule of particle diameter.Therefore, filtrate wall 3 can be removed organic matter when removing SS, reduces COD and colourity etc.
The operation principle of coagulating sedimentation separator of the present invention:
Water inlet is passed through the bottom that water inlet pipe 1 gets in the central cylinder 6 by the intake pump of outside, is flowed out by the waterpower release that links to each other with water inlet pipe 18, and current are spurting outside all around.Coagulant enters into first doser, 13 addings that central cylinder 6 inner bottom parts are attached thereto by the medicine machine of outside through first chemical feed pipe 2.Because the perforate direction of first doser 13 is horizontal centripetal direction in the inboard, therefore, coagulant is sprayed along horizontal centripetal direction by aperture, and is just in time relative with the water (flow) direction of waterpower release 8 injections, reaches quick well-mixed effect.Mixed water is flowed by the bottom of central cylinder 6 from bottom to top, and second doser, 12, the second dosers 12 that process central cylinder 6 tops are provided with are linked to each other with the medicine machine of outside by second chemical feed pipe 9 and carry out adding of flocculation aid.Because the perforate direction of second doser 12 is the downward 45 ° of centripetal directions of inboard level, therefore, flocculation aid is sprayed along the downward 45 ° of directions entad of level by aperture, fully contacts with current, improves coagulation condition and flco structure, improves coagulation effect.Then, the water overflow gets into the reaction precipitation district at central cylinder 6 shell bodies 5 middle parts, and the flco that coagulation produces gathers bigger and bigger at this, and speed is sunken to the centrum part of housing 5 bottoms more and more sooner, forms mud, and clear water then gets into housing 5 tops, accomplishes mud-water separation.Housing 5 tops are provided with filtrate wall 3 it are divided into effluent trough 4 and Filtration Adsorption district, and the water of post precipitation gets into the Filtration Adsorption district on housing 5 tops, through the Filtration Adsorption effect of filtrate wall 3; Fine particle and impurity are trapped within the filtration side; Reassociate into bulky grain and get into the settling zone, simultaneously, the organic matter in the water etc. are by the charcoal absorption in the filtrate wall 3; When reducing SS, reduce COD and colourity etc.; Improve effluent quality, clear water then sees through filtrate wall 3 and gets into effluent trough 4, passes housing 5 by the outlet pipe 11 that is provided with in the effluent trough 4 and discharges.Mud comes together in the centrum part of housing 5 bottoms, is discharged through 14 controls of the mud valve on it by the discharge pipeline 15 that is arranged at the centrum bottom.Long-time running, filtrate wall 3 can make water outlet not cause freely that water level rises because of the absorption of impurity, when water level rises to limiting water level; Automatically control intake pump and medicine machine stops into water and dosing by PLC; Clean, during cleaning, only need filtrate wall 3 is proposed externally to clean; Packing into after the cleaning gets final product, simple and convenient.If higher, can consider to upgrade filtrate wall 3 to water quality requirement.
Coagulating sedimentation separator of the present invention both can be used for sewage disposal, can be used for middle water treatment again, also can be used for the purified treatment of drinking water.
Certainly, above-mentioned explanation is not to be limitation of the present invention, and the present invention is not limited to above-mentioned giving an example, those skilled in the art, and in essential scope of the present invention, the variation of making, remodeling, interpolation or replacement all should belong to protection scope of the present invention.
