摘要
利用生物陶粒作为悬浮填料移动床(MBBR)的填料处理南方城镇低含量污染物生活污水,考察了水力负荷、有机负荷对反应器运行性能的影响,进一步探究系统运行边界条件。结果表明,生物陶粒MBBR最高可承受0.9m3.m-2.h-1的水力负荷,COD、NH4+-N、TN去除率分别为64.71%、58.12%、37.54%;HRT为6 h条件下,系统可承受低于1.0 kg.m-.3d-1的有机负荷冲击,出水COD和NH4+-N、TN的质量浓度均可达到GB 18918-2002一级标准。
Using bio-ceramic as a filler in MBBR reactor to purify southen town's low-concentration domestic sewage,the effects of the influential factors by different hydraulic load and organic load on a MBBR reactor had been studied,and further explored the boundary conditions of system operation.The results revealed that: the bio-ceramic MBBR could affordable 0.9 m3·m-2·h-1 of the hydraulic loading,the removal rate of COD,NH4+-N,TN reached to 64.71%,58.12%,37.54%;HRT was 6 h,the system could withstand less than 1.0 kg·m-3·d-1 of organic loading shock,the effluent of COD,NH4+-N,TN could meet I-class criteria of urban wastewater treatment plant emission standards(GB 18918-2002).
