Abstract
The invention discloses a chemical processor for sewage. The chemical reactor is composed of a stirring zone, a depositing zone and a repeat flowing path formed among channeling layers. Active sludge is deposited and concentrated in the stirring zone; and then the active sludge is continuously circulated in the repeat flowing path to bring mixed liquid back into the depositing zone. The chemical reactor is simple in structure and convenient to operate. Subsequent processing equipment needed in a normal pressurizing biochemical method is reduced in the chemical processor for the sewage; a built-in type solid-liquid separating device is utilized for separating solid from liquid automatically; and therefore, a subsequent depositing processing step is saved, technology process equipment is simplified and running cost of the chemical processor is reduced.
Description
Technical field
The present invention relates to a kind of chemical processor of sewage, be applicable under aerobic, anoxic or anaerobic condition, process organic waste water.
Background technology
Second-stage treatment in most cities sewage work just adopts suspension growth technique to remove the solvability organic pollutant.Suspension growth technique contains a suspension growth forensic chemistry reactor and a settling tank.In sewage treatment process, sewage and the active sludge that refluxes from settling tank enter the aeration tank, and aerating system also constantly is provided to air or oxygen in the aeration tank simultaneously.Pollutent can be degraded by active sludge in the aeration tank or adsorb.Then treated mixed liquid enter settling tank and carry out solid-liquid separation.Supernatant liquor after the precipitation flows out settling tank.The most of activated sludge that precipitates then is back to the aeration tank to keep the sludge concentration in the reactor.Residual active sludge then is discharged into the sludge disposal system and is further processed and disposes.
Active sludge is the fresh combatants of removing pollutent, so the processing power of chemical reactor can improve with the raising of activated sludge concentration in the reactor.Therefore, only rely on raising activity sludge reflux flow can not guarantee that higher activated sludge concentration is arranged in the chemical reactor.The chemical processor that in current life, needs a kind of sewage.
Summary of the invention
The objective of the invention is: the suspension growth forensic chemistry reactor that provides a kind of chemical processor of sewage that active sludge is refluxed in reactor, thereby simplify the operation and save the energy and reduce hydraulic load and the solid loading enter settling tank, improve the effluent quality of settling tank.
Technical scheme of the present invention is: a kind of chemical processor of sewage, it is characterized in that: the chemical processor of described sewage forms stirring area, settling region and flow passage repeatedly by helping logical layer and helping between the logical layer, described active sludge precipitates in stirring area and is concentrated, then by in the flow passage repeatedly constantly circulation will mix liquid and bring back to the settling region, the chemical processor of described sewage has reduced the handling equipment for offspring necessaries of conventional compression biochemical method, adopts built-in equipment for separating liquid from solid automatically to carry out liquid-solid separation.
Preparation method of the present invention is: the chemical processor of sewage of the present invention has a water entry and a water dispensing apparatus that links to each other, discharge water passage and a water storage device that links to each other, a drain; Lead to layer built-in the helping of treater, be separated to form stirring area, settling region and flow passage repeatedly in the chemical processor with sewage, described repeatedly flow passage makes the afterbody of quiescent centre be connected with stirring area, is provided with the stirring that whipping device is used for active sludge and sewage in stirring area.
Advantage of the present invention is: a kind of chemical processor of sewage has reduced the handling equipment for offspring necessaries of conventional compression biochemical method, adopt built-in equipment for separating liquid from solid automatically to carry out liquid-solid separation, save the post precipitation processing, simplified technological process apparatus, reduced running cost.
Embodiment
Embodiment of the present invention depend on the requirement of sewage disposal, and mixed equipment can be air mixture apparatus, mechanical mixing equipment or waterpower mixing equipment etc.In the mixed district of chemical reactor, the pollutent in the sewage is degraded under aerobic or anoxic or anaerobic condition, and the denseer sludge reflux in bottom arrives in the mixed district.
