| 摘 要： | 以生活污水为供试水样,通过讨论曝气时间、污泥负荷、厌氧好氧时间分配、pH值等因素对SBR反应器中污水COD去除效果的影响进行研究。结果表明:在室温(20±5)℃和进水pH值为6.45—7.55条件下,SBR反应器优化的运行参数为厌氧150 min、曝气120 min、沉淀60 min,污泥负荷为0.049—0.082 kg BOD5/kg MLSS,MLSS 3000—5000 mg.L-1。在此条件下,COD、BOD5、NH3—N、TP和SS的平均去除率分别为85.45%、95.23%、80.25%、95.04%和85.84%,出水水质可满足城镇污水处理厂污染物排放标准(GB18918-2002)一级A。

| Abstract: | The effects of aeration time,sludge load,distribution of aeration and anaerobic time,and pH value on COD removal of wastewater in the sequencing batch reactor(SBR) were discussed by the domestic wastewater samples.The results show that optimization operation parameters of anaerobic time,aeration time and sedimentation time with SBR are 2.5 h,2.0 h and 1.0 h if air temperature is 20±5 ℃ in the room and pH value of inlet reaches 6.45—7.55,and the sludge load and the concentration of mixed liquid suspended substance(MLSS) are 0.049—0.082 kg BOD5/kg and 3000—5000 mg·L-1,respectively.Under these optimization conditions,the average removal rates of COD,BOD5,NH3—N,TP and SS are 85.45%,95.23%,80.25%,95.04% and 85.84%.The water quality of outlet can reach the grade A of "discharge standard of pollutants for municipal wastewater treatment plan(GB 18918-2002). |
