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WSIP反应器脱氮效能影响因素试验研究,旨在对运行参数优化,提高渗滤液脱氮效能。试验表明,随HRT降低,NH4+-N去除率迅速下降;TN去除率先升后降,以5.3d为最高;NH4+-N、TN去除率随序批周期减小先升后降,分别在8h、6h时达到最高;NH4+-N去除率随每日曝气时间上升而增加,TN去除率则先升后降,在曝气时间为9h·d-1时达到最高;温度升高WSIP反应器脱氮效能提高;随pH值升高,NH4+-N、TN去除率先升后降,pH=8.0左右NH4+-N、TN去除率最高;随进水磷浓度升高,氮磷比降低,NH4+-N、TN去除率升高,但需控制出水磷浓度。
The experiment is based on Heishizi landfill lechate treatment, and contrapose its limitation, aim at optimizing WSIP＇s function parameter and increasing disposal efficiency.Results shown that with HRT＇s droping, removal rate of NH4^＋-N decreased, TN is highest in case of HRT=5.3 d; removal rate of NH4^＋-N increase with rising aeration time, TN is highest while aeration time is of 9 h·d^-1; removal rate of NH4^＋-N,TN increase with temperature rising; removal rate of NH4^＋-N,TN is highest at pH about 8.0; with concentrate of TP rising, removal rate of NH4^＋-N ,TN increase, but exceed water＇s concentrate of TP should be controlled.
