氨氮浓度作为新型SBR工艺影响因素的研究
首发时间:2006-08-18
摘要:实验研究NH4+-N浓度对新型SBR工艺中脱氮除磷的影响,得出NH4+-N浓度在50mg/l~150mg/l范围内,本工艺的CODcr、NH4+-N、TN、TP的处理效果差别明显,CODcr去除率相差18%,NH4+-N去除率降低38%,TN的去除率下降32%,而TP的去除率一直都低,出水TP指标都超标。说明本工艺的氨氮浓度增加对有机物的去除和脱氮除磷有显著的影响。

Study on Affecting Factors of Ammonia Nitrogenous Concentration with Modified SBR System
Abstract: Influence of ammonia nitrogenous concentration on removal of nitrogen and phosphorus with modified SBR system was investigated. The results showed that the concentration of Ammonia nitrogen was 50~150mg/L, the removal rates of CODcr, NH4+-N, TN and TP had difference simply. CODcr, NH4+-N and TN lowed 18%, 38% and 32%, the removal rates of TP was low all the time. The results showed that ammonia nitrogenous concentration had important impact with modified SBR in removal of TN and TP.
