摘要
以改性丝竹作为生物载体和缓释碳源构建了好氧挡板式生物膜反应器(ABBR),研究了其对城市污水处理厂尾水中氮素化合物的去除效果和特性。结果表明:当HRT为8 h时,TN和NO3--N去除率分别可达66.58%~75.23%和50.96%~66.43%。以丝竹为单一碳源,NO3--N去除速率达2.13 mg/(L·h)。相比于弹性立体填料,以改性丝竹作为生物载体可以获得较高的NO3--N去除率和较低的NO2--N积累率。
An aerobic baffled biofilm reactor(ABBR)was developed with modified filamentous bamboo as biocarriers and slow released carbon source,the removal effects and characteristics of nitrogenous compounds from effluent of municipal wastewater treatment plants by which were investigated.The results showed that the removal rates of TN and NO3--N reached 66.58%-75.23%and 50.96%-66.43%,respectively,when HRT was 8 h.The removal rate of NO3--N was 2.13 mg/(L·h),when modified filamentous bamboo was used as single carbon source.Compared to elas-tic packing,the biological nitrogen removal system with filamentous bamboo could obtained higher NO3--N removal rate and lower NO2--N accumulation rate.
