多因素影响下SUFR系统除磷效果研究
Study on phosphorus removal effects of SUFR process under influences of different factors
摘要
Abstract
An orthogonal test was designed in order to explore the effects of SRT,C/N and C/P on phosphorus removal when the influent COD concentration was 300～400 mg/L.The results showed that SRT was the main factor affecting the phosphorus release and uptake rates.The phosphorus removal efficiency decreased with increasing SRT.The growth of influent C/N and C/P inhibited the proliferation of the activated sludge by decreasing the influent TN and TP concentration and thereby inhibited the phosphorus release and uptake rates.C/P also greatly affected the TP removal rate of SUFR system,but it mainly changed the base of the removal rate though changing the influent TP.关键词
