Description
Technical field
The utility model relates to sewage treatment area, more specifically relates to series flow of sewage A2O biochemical reaction and mud static state deposition integrated apparatus, is applicable to the processing of industry and sanitary sewage.
Background technology
In waste water biochemical treatment method, adopt anaerobism-anoxic-aerobic activated sludge process, carry out A2O (Anaerobic-Anoxic-Oxic) sewage treatment process of biological carbon elimination denitrogenation dephosphorizing, its general flow chart refers to accompanying drawing l, and wherein l is water main inlet port, and the 2nd, anaerobic pond, the 3rd, anoxic pond, the 4th, time water-in, the 5th, aerobic biochemical (nitrated) pond, the 6th, settling tank, the 7th, water outlet, the 8th, mixed-liquor return, the 9th, sludge reflux, the 10th, mud relief outlet.
The advantage of existing A2O technique, that the nitre state oxygen making full use of in denitrification process in nitrification liquid is oxidized BOD5, reclaimed the oxygen requirement of part nitration reaction, the basicity that the basicity that anti-nitration reaction produces can partial-compensation nitration reaction consumes, therefore to containing the another exogenously added alkali adjusting pH of the not high sewage of nitrogen concentration.This technique is the simplest dephosphorization and denitrification process in system, and total hydraulic detention time is less than other similar technique (as Pu of Baden dephosphorization and denitrification process); Under the condition of anaerobism, anoxic, aerobic alternate run, thread fungus can not amount reproduction, and without the anxiety of sludge bulking, SVI-value is less than 100, is beneficial to the separated of sewage and mud after processing; The only light and slow stirring of need in anaerobism section and anoxic section in service, working cost is low.Owing to dividing and be arranged in anaerobism, anoxic, aerobic reaction pond, so its dephosphorization and denitrification effect is compared with high and stable.
The shortcoming of existing A2O technique, mainly be that its biological denitrificaion need to keep lower sludge loading, to fully carry out nitrated, reach higher denitrification percent, biological phosphate-eliminating needs the sludge loading that remains higher, keeps larger surplus sludge volume, to reach good phosphor-removing effect, therefore need to take necessary optimized Measures, to relax both contradiction.
Secondly, in existing A2O activated sludge process continuous flow sewage treatment process, in order to obtain clean processing water outlet, must be by the sewage mixed solution that contains suspension active sludge (lower be called for short " mud and sewage mixed solution "), by independent solid-liquid separation facility is set, as clarify settling tank, membrane separation unit etc., carry out the solid-liquid separation of mud and clear water.
For taking, clarification settling tank is set, allows suspension active sludge by gravity settling, form the water-containing sludge of high density, fall to settling tank bottom separated with clarification clean water, clarification clean water in upper strata is discharged from settling tank surface; The method need to arrange the clarification settling tank with certain settling zone, and residence time of settling down of the active sludge that keeps enough making suspending, and this causes the volume space size of whole waste disposal plant to increase, and has increased and has taken up an area and investment; The structures such as sludge reflux, mud and sewage mixed-liquor return pump house must be set in addition, cause technical process comparatively complicated, power consumption increases, and management is inconvenient, and floor space is larger.And for adopting membrane separation unit, generally with micro-filtration or ultra-filtration membrane as solid-liquid separation filtration medium, mud and sewage mixed solution is passed through to the micro-pore-film filtration method of molecular level, allow the material of water and other molecular level under certain pressure, from micropore, see through film, form relatively clean filtration water outlet, separated with high-concentration suspension mud mixed liquid.The advantage of membrane separation technique is to obtain the clean clean water almost complete absence of suspended sludge, but there is following shortcoming, the one, the manufacturing cost of micro-filtration or ultra-filtration membrane is very high, the 2nd, the water permeation flux of film is lower, the 3rd, need to regularly carry out matting in case film pollutes, the 4th, must be with pump by the pressurization of mud and sewage mixed solution or suction, to can carry out normal filtration under certain pressure, this causes higher water level pressure head or the aspiration vacuum power of pumping, and running cost is increased.
