曝气生物滤池处理农村生活污水效率与微生物群落分析
Efficiency and microbial community analysis of domestic sewage treatment by biological aerated filter
摘要
Abstract
Taking rural domestic sewage in Daxing district of Beijing as an object,this paper designed four reaction columns,and studied the effect of biological aerated filters (BAF) on the efficiency of rural domestic sewage treatment and microbial community under three different filling structures and two gas water ratio.The removal rate of BOD5,CODCr and ammonia nitrogen in #1,#2 and #3 column which had different filling structures and same gas water ratio reached 84.51％-96.49％;#4 column and #2 column had the same filling structure,but the gas water ratio was small,and the treatment effect of BOD5 and CODcr was very poor;however,all the removal rate of TP are low,so phosphorus removal measures need to be strengthened.The difference of OTU in #1,#2 and #3 columns were very small,which indicating that the number of microbial species was basically the same;the specific OTU number of #2 column was much larger than that of #4 column,indicating that high gas water ratio was favorable to the increase of microbial species.There were 6 dominant bacteria groups in #1,#2 and #3 columns,the dominant species of each reaction column were basically the same at different heights,but the quantity was different.Only Proteobacteria may contain poly P bacteria in these 3 reaction columns,which was also one of the reasons for poor phosphorus removal.关键词
