Traditional sewage treatment process is obvious to all in the advantage of big-and-middle-sized sewage work, but as realized the regeneration of sewage, need to transform technique, the application of traditional technology in middle-size and small-size cities and towns simultaneously is also subject to the restriction in construction investment and working cost etc., and existing middle-size and small-size sewage disposal is provided with and mainly contains traditional film-bioreactor and traditional anaerobic reactor.
Traditional film-bioreactor (Membrane Bioreactor, MBR) is combined system application of membrane formed in bio-reactor.Solid-liquid separation film-bioreactor studies the class film-bioreactor be most widely used at present.Membrane module is in order to replace the second pond in traditional activated sludge process in the process, plays the effect of solid microbe in isolating active mud mixed liquid and macromole dissolved matter.The technology of current MBR technique is ripe day by day, but it applies the restriction being but subject to two large factors: one be the organic or inorganic film price that usually adopts costly, cause the initial cost of MBR technique higher; Two is that fouling membrane is wayward, and aerobic membrane bioreactor (MBR technique) is the pollutent by removing at aerobic process in sewage, and membrane module carries out mud-water separation.Its working process needs to issue continuous aeration at film group device, and controlling diaphragm pollutes, and the aeration that film aeration needs is huge, and therefore operation energy consumption is high.And general anaerobic membrane bioreactor (AnMBR) pollutes in order to controlling diaphragm, ensure the cross flow filter of face, general employing methane aeration or mixed solution at a high speed backflow form the cross flow filter of film.Adopt methane aeration to there is potential safety hazard, backflow energy consumption is high at a high speed to use mixed solution, and easy broken anaerobic sludge, working cost is higher simultaneously.
Tradition anaerobic reactor (as UASB, EGSB, IC etc.), its mud-water separation is generally by gravity settling, and the enrichment of anaerobic sludge needs high loading to support, and therefore can not process low concentration wastewater, follow-uply must increase aerobic treatment unit.
