摘要
本文介绍了一种新的化学强化生物除磷工艺及其设计实例,与Phostrip侧流除磷工艺相比,其工艺优势在于所有污泥均经释磷和厌氧选择处理,通过化学沉积释放的磷,从而消除了在污泥处置过程中产生的磷释放回到污水处理系统的问题;所有回流污泥经厌氧选择处理,含有较高浓度聚磷菌类微生物,从而具有较高的除磷效率。
A new technological process for phosphorus removal by enforced chemical and biological processes is introduced in this paper. In comparison by the phostrip process for phosphorus removal, its superiorities lie in that all sludge releases phosphorus through phosphorus release, anaerobic treatment and chemical sediment, thus eliminating the problem of released phosphorus retuming to sewage treatment system generating in the course of sludge disposal; all reflux sludge, through anaerobic selection, contains high strength poly-phosphate accumulating organisms, thus possessing higher phosphorus removal effect.
