反硝化的

Six kind of bacteria were isolated from the mixture, and it was approved is that when the temperature was 30~35 oC ,pH was 8.0,DO＜1.2mg/L,the condition was adapted to Nitrosomas and the rate of remove about ammoniate was more than 80%.

得出在温度为30-35oC， pH值为8.0，DO＜1.2mg/L的条件下，最适合混培物的生长，氨氮的去除率可达80%以上，从而有效地降低抑制作用，使得后续反硝化能够顺利进行。

Based on the previous studies and combined with the national important scientific special item—the projection of water environment improvement and comprehensive demonstration in Suzhou city. The influence to water quality melioration under different conditions of packing types, stuffing rate, air supply and hydraulic loading using water of Miaojia river as experiment water sample; the water contaminate removal ability by the absorption and interception of charcoal filling and the research of the denitrification rate of charcoal filling were discussed in the paper. Furthermore, the activity of the biofilm on savageness and artificialness filling surface in the projection demonstration riverway were also analyses.
