Abstract

Abstract:

Systematical analysis by using sequencing batch reactors （SBR） has been made on the characteristics of denitrifying phosphorus removed sludge at normal and low temperatures （25 ℃ and 15 ℃）.The results indicate that the DPB sludge has better settlement capacity at both normal and low temperatures.The total phosphorus is 2.3%-3.7% and 1.6%-2.1% respectively.The ratio of DPB to PAOs （RDPB） is 77% and 51%.VSS/SS is 76%-88.6% and 74%-85.3%, respectively.There are some protozoa, such as vorticella and a bit of philodina, in the DPB sludge at low temperature.It is possible to increase the phosphorus removal rate by increasing the concentration of sludge and prolonging the reaction time.

Key words: denitrifying phosphorus removal sludge, characteristic of sludge, phosphorus-containing ratio

摘要：

在低温(15℃)与常温(25℃)条件下,用SBR反应器对反硝化除磷污泥特性进行了系统分析.结果表明,在常温与低温条件下反硝化除磷菌(DPB)污泥均具有较好的沉降性能;总磷质量分数分别为2.3%～3.7%和1.6%～2.1%;DPB占总PAOs的质量分数(RDPB)分别约为77%和51%;VSS/SS分别为76%～88.6%和74%～85.3%.低温下DPB污泥中存在钟虫和少量轮虫等原生动物.低温下DPB污泥系统运行正常,可通过增加污泥浓度和延长反应时间以提高除磷率.
