| 摘 要： | 采用UASB中试(100 m3/d)对生活污水处理进行了研究。试验结果表明,采用此系统处理生活污水,出水水质良好。COD的去除率在52%~83%,出水的COD值<100 mg/L以下,SS的去除率在95%左右,UASB处理生活污水的最佳停留时间为6 h。产气率在0.1 m3/d。不管停留时间在10 h、5 h,出水的氨氮、乙酸值比进水的高;钙、镁、总氮、总磷、硫酸根和硝酸根离子出水值比进水值低。

| Abstract: | Municipal wastewater treatment with UASB pilot scale(100 m~3/d) is studied.The results of the experiment indicate: using this system to deal with the municipal wastewater,the quality of effluent water is good.The removal rate of COD is in 52%~83%.The value of COD of effluent water is smaller than 100 mg/L,the removal rate of SS is about 95%.When UASB is used to treat municipal wastewater,the best retention time is 6 hours.The rate of gas production is 0.1 m~3/d.No matter the retention time is 10 hours or 5 hours,the ammonia nitrogen and the values of acetic acid in effluent water are higher than those in influent water.The values of calcium,magnesium,total nitrogen,total phosphorus,both the root of sulfuric acid and root of nitric acid in effluent water are lower than those in influent water. |
