摘要
以实际污水处理厂沉砂池出水为研究对象,试验研究了冬季低温条件下"上流式多功能生物反应器+好氧池+二沉池"工艺对低碳源南方城市污水的脱氮除磷效果。该生物反应器采用上向流形式,综合了初沉池、厌氧池、缺氧池的功能。结果表明:新工艺在低温条件下能保持良好的硝化、反硝化功能,出水COD、TN和NH+4-N可稳定达一级A排放标准,出水TP效果可通过增大处理规模、控制规律排泥进一步提高。
Using the effluent of settling pond in sewage treatment plant as the research object, the experimental research on denitrification and dephophorization effect of southern city sewage with low corbon-resource by ＂upflow multi-function bioreactor ＋ aerobic tank ＋ second settling tank＂ process in a low temperature. This bioreactor features a upward flow and has the comprehensive function of the primary settling tank, anaerobic tank and anoxic tank. The results showed that the new process can maintain good nitrifying and denitrifying function in a low temperature and the concentration of COD,TN and NH4^＋ -N in the effluent can steadily meet the requirements of the level A of discharge standard. The effect of TP can be improved by increasing the processing scale and regulating sludge discharge.
