The processing mechanism of coagulating sedimentation separator of the present invention:
A, coagulation
Colloid pollution thing in water, because the effect of ζ-potential forms stabilising system, is difficult to natural sedimentation and separates, and need add medicament and improve.This coagulating sedimentation separator is by adding counter ion coagulant, electrically neutralize with the colloid pollution deposits yields in water, reduce ζ-potential, compression double electric layer, so de-steady, simultaneously, coagulant has linear structure through the high polymer being hydrolyzed and polycondensation reaction forms, with the strong adsorption bridging effect of colloid pollution deposits yields in water, form large floc particle and sink, be beneficial to precipitation.Coagulation comprises and mixes and react two stages, the effect mixing is to make medicament to be diffused into equably rapidly in water to create good hydrolysis and polymerizing condition, meanwhile elimination of colloid stability completes immediately and condenses by Brownian movement and the turbulent flow of particle, this coagulating sedimentation separator utilizes subtend setting and the pressure control of the water inlet pipe 1 waterpower release 8 of lower end connection and the perforate direction of the first doser 13, in the interior fine mixed process that completes of central cylinder 6.Mixed current are flowed from bottom to top by central cylinder 6, overflow central cylinder 6 and enter housing 5 middle parts, and speed slows down successively and enters the stage of reaction.In addition, due to adding of flocculation aid, regulate or improved coagulation condition (as pH etc.), improving 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, the flco that above-mentioned coagulation produces, and more poly-larger at housing 5 middle parts, speed is sunken to the centrum part of housing 5 bottoms more and more sooner, forms mud, and clear water enters top, completes mud-water separation.
C, filtration
The filtrate wall 3 of this coagulating sedimentation separator setting has tiny space, has mechanical retention filtration.Effluent stream through time, filtrate wall 3 is trapped in effluent trough outside in large quantities by the fine particle not precipitating in water, then forms bulky grain and enter settling zone, clear water sees through filtrate wall 3 and enters in effluent trough 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 larger porosity and specific area, can adsorb the molecule that particle diameter is suitable.Therefore, filtrate wall 3, when removing SS, can be removed organic matter, reduces COD and colourity etc.
The operation principle of coagulating sedimentation separator of the present invention:
Water inlet enters the bottom in central cylinder 6 by outside intake pump by water inlet pipe 1, by the waterpower release 8 being connected with water inlet pipe 1, is flowed out, and current are spurting outside surrounding.Coagulant enters into through the first chemical feed pipe 2 the first doser 13 that central cylinder 6 inner bottom parts are attached thereto by outside medicine machine and adds.Due to the perforate direction of the first doser 13 in inner side horizontal centripetal direction, therefore, coagulant is sprayed along horizontal centripetal direction by aperture, the water (flow) direction of just in time spraying with waterpower release 8 is relative, reaches quick well-mixed effect.Mixed water is flowed from bottom to top by the bottom of central cylinder 6, and the second doser 12, the second dosers 12 that arrange through central cylinder 6 tops are connected and carry out adding of flocculation aid with outside medicine machine by the second chemical feed pipe 9.Because the perforate direction of the second doser 12 is the downward 45 ° of centripetal directions of inner side level, therefore, flocculation aid is sprayed along the downward 45 ° of centripetal directions of level by aperture, fully contacts with current, improves coagulation condition and flco structure, improves coagulation effect.Then, water overflow enters the reaction precipitation district at central cylinder 6 shell body 5 middle parts, the flco that coagulation produces, and more poly-larger at this, speed is sunken to the centrum part of housing 5 bottoms more and more sooner, forms mud, and clear water enters housing 5 tops, completes mud-water separation.Housing 5 tops arrange filtrate wall 3 and are divided into effluent trough 4 and filter adsorption zone, water after precipitation enters the filtration adsorption zone on housing 5 tops, through the filtration suction-operated of filtrate wall 3, fine particle and impurity are trapped within filtration side, reassociate into bulky grain and enter settling zone, simultaneously, organic matters in water etc. are by the charcoal absorption in filtrate wall 3, when reducing SS, reduce COD and colourity etc., improve effluent quality, clear water sees through filtrate wall 3 and enters effluent trough 4, passes housing 5 discharge by the outlet pipe 11 of effluent trough 4 interior settings.Mud comes together in the centrum part of housing 5 bottoms, by the discharge pipeline 15 that is arranged at centrum bottom, by the mud valve 14 on it, controls discharge.Long-term operation, filtrate wall 3 can freely not cause that water level rises because the absorption of impurity makes water outlet, when water level rises to limiting water level, by PLC, automatically control intake pump and medicine machine stops into water and dosing, clean, during cleaning, only filtrate wall 3 need be proposed in exterior washings, after cleaning, pack into, simple and convenient.If higher to water quality requirement, can consider to upgrade filtrate wall 3.
Coagulating sedimentation separator of the present invention both can be used for sewage disposal, can be used for again middle water treatment, also can be used for the purified treatment of drinking water.
Certainly, above-mentioned explanation is not 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, variation, remodeling, interpolation or the replacement made, all should belong to protection scope of the present invention.
