| 摘 要： | 无锡市充山水厂采用BIOSMEDI生物滤池对微污染原水进行预处理,采取自然挂膜的启动方式,在平均水温为22.7℃的条件下,大约运行12 d后,对氨氮的去除率稳定在60%以上,至此认为生物滤池挂膜成功.在BIOSMEDI生物滤池满负荷运行条件下,其对COD_(Mn)、氨氮、亚硝酸盐氮和藻类的平均去除率分别为9.6%、71.7%、42.7%和20.7%,达到了预处理的目的.

| Abstract: | BIOSMEDI biofiher was adopted to pretreat the micro-polluted raw water in Chongshan Waterworks in Wuxi. Under the conditions of natural start-up, average water temperature of 22.7 ℃ and
running time of 12 d, the removal rate of ammonia nitrogen is above 60%, which indicates the biofilm has been formed. Under full-load running of BIOSMEDI biofiher, the average removal rates of COD_(Mn),ammonia nitrogen, nitrite nitrogen and algae are 9.6%, 71.7%, 42.7% and 20.7%, achieving the goal of biologieal pretreatment of micro-polluted raw water. |
