【摘要】 利用悬挂式软性纤维填料制备了生物接触氧化塔,并对生活小区污水进行处理,三个月的试验结果,表明:在HRT=3h的条件下,当原水COD在300～400mg/L,氨氮在30～80mg/L范围时,出水氨氮<1mg/L、COD<50mg/L、SS<15mg/L,此时,系统硝化负荷最高达0.50kg/(m3·d)有机负荷最高达3.2kg/(m3·d)。由实验结果得出,HRT为1.5h,在有机负荷2kg/(m3·d)时,水力负荷是影响硝化的关键因素。更多还原

【Abstract】 Bio-contact oxidation tower with hanging fibre media was used to treat the wastewater of a residential district.When HRT is 3h,COD is between 300 and 400 mg/L and NH₃-N between 30 and 80 mg/L in the influene,after treatment COD decreased to 50mg/L,NH₃-N<1 mg/L and SS<15mg/L in the efluent in case of maximal nitrogen load 0.5kg/（m3·d ）and maximal organic load 3.2kg/（m3·d）. The results showed when organic load 2.0kg/（m3·d）,the hydraulic load is the key factor for nitrofication,and HRT must be greater than 1.5h.更多还原
