摘要
以黑石子垃圾渗滤液强化预处理-生物接触氧化处理技术为依托,针对其处理效果的局限性,进行SBBR反应器脱氮效能影响因素试验研究,旨在优化运行参数,提高渗滤液处理效能。得出以下结论:一/二阶SBBR反应器对COD、NH4+-N、TN的去除效果分别以HRT为8d/4d、8d/4d～12d/6d、12d/6d时最为理想;COD、NH4+-N去除率随序批周期减小而升高,TN去除率随序批周期减小先升后降,在序批周期为6h时达到最高;COD、NH4+-N去除率随溶解氧、周期曝气时间升高而增加;TN去除率则先升后降,在一/二阶SBBR反应器曝气时DO平均浓度约为2.0/2.5mg·L-1,周期曝气时间为3h时去除率最高;SBBR反应器处理效能随温度升高明显提高。
his experiment is based on Heishizi landfill lechate treatment, and contrapose its limitation, aim at optimizing SBBR＇s function parameter and increasing disposal efficiency. As the first/second SBBR＇s HRT is 8 d/4 d ,8 d/4 d-12 d/6 d, 12 d/6 d, removal rate of COD ,NH4^＋-N ,TN are the most favourable; Removal rate of COD ,NH4^＋-N increase with droping period time, while that of TN is highest in case of period time is of 6 h; removal rate of COD ,NH4^＋-N increase with rising DO and period aeration time, while that of TN is highest in case of period aeration time is of 3 h and he first/second SBBR＇s DO=2.0/2.5 mg·L^-1; Removal rate of COD ,NH^＋-N ,TN increase with temperature rising.
