摘要: Activated sludge sewage treatment process comprising aerating a mixed liquor phosphate-containing influent material to cause the microorganisms present take up phosphate, separating phosphate-enriched from liquor, and settling separated in phosphate stripping zone form supernatant settled sludge. At least part of is maintained under anaerobic conditions release soluble resulting containing released contacted with lower content medium effect enrichment zone, at portion being recirculated aeration zone.
