摘要： Contaminated wastewaters comprising biochemical oxygen demand (BOD), nitrogen and phosphorus are treated by an activated sludge process. The process utilizes an activated sludge tank, a solid-liquid separator, and a bioreactor to significantly reduce, or eliminate, waste activated sludge (WAS) within a sludge stream. A sidestream reactor is employed downstream from the bioreactor to remove soluble phosphates left in the sludge stream by the low WAS process. Within the sidestream reactor, a source of multivalent metal ions is added to a slightly alkaline sludge stream to precipitate the phosphates. The solid phosphates have a specific gravity higher than that of the organic matter in the sludge stream and may be separated from the sludge stream based upon differential settling velocity.

摘要： A process for treating BOD, nitrogen and phosphorus containing wastewater, wherein the process includes providing wastewater influent into an anaerobic zone having activated sludge and mixing the wastewater influent with the activated sludge in the anaerobic zone to form a mixed liquor. The process further includes providing the mixed liquor into an oxygen-deficit aeration zone and recycling denitrified mixed liquor from the oxygen-deficit aeration zone to the anaerobic zone for mixing therein with wastewater. In addition, the process includes transferring the mixed liquor from the oxygen-deficit aeration zone to an oxygen-surplus aeration zone and transferring a portion of the mixed liquor from the oxygen-surplus aeration zone to a membrane filter wherein a filtrate is separated from sludge. The process also includes recycling at least a portion of the sludge to the oxygen-deficit aeration zone as recycled activated sludge.
