摘要
采用悬浮载体SBR工艺对生活污水进行了正常负荷及冲击负荷对比运行实验。结果表明:正常负荷运行时,出水CODCr稳定在12—32 mg/L,去除率保持在90%以上;脱氮除磷效果较好,出水氨氮和总磷分别稳定在2.3—4.2 mg/L和0.22—0.49 mg/L,均达到GB18918-2002中一级A标准要求;系统抗冲击负荷能力强,在进水CODCr提高5倍的情况下,其去除率仍保持在85%以上;冲击负荷对脱氮除磷效果影响较大,氨氮和总磷的去除率均由正常情况下的85%左右下降至50%左右。
Experiments of normal load and high impact load on domestic sewage treatment by suspended-carrier SBR process were conducted comparatively. The results indicated that： in the normal load experiment, effluent CODcr was 12--32 mg/L and its removal rate kept over 90%. NH3-N and TP in the effluent were stable at 2.3-- 4.2 mg / L and 0.22--0.49 mg / L respectively. All these parameters met l-level A standard of GB18918-2002. High impact load had great effect on removing nitrogen and phosphorus. Both the removal rate of NH3-N and that of TP dropped from about 85% to 50%.
