| 摘 要： | 采用水解酸化-厌氧-改良Carrousel氧化沟组合的脱氮除磷工艺,进行混合型城市污水处理的试验研究。在不同的水力停留时间(HRT)下,分别试验测定了水解酸化池进出水的各项指标。结果表明:最佳水力停留时间(HRT)为3 h,进水ρ(COD)为150～1 200 mg/L、ρ(NH3-N)为12～40 mg/L、ρ(TN)为14～58 mg/L、ρ(TP)为1.7～4.2 mg/L,所对应的去除率COD为-29%～66%、NH3-N为-55%～33%、TN为-45%～69%、TP为-80%～66%。可见基于水解酸化工艺预处理可成功实现混合型城市污水中有机物的水解和酸化。

| Abstract: | An experimental study on treatment of composite urban wastewater treatment with hydrolysis acidification-anaerobic-modified Carrousel oxidation ditch process was conducted.At different hydraulic retention time(HRT),it was determined the indicators of the influent and efflucent in the hydrolysis acidification tank.The results indicated that the optimal hydraulic retention time(HRT) was 3 h,influent COD was 150~1 200 mg/L,NH3-N was 12~40 mg/L,TN was 14~58 mg/L,TP was 1.7~4.2 mg/L,the corresponding to the COD removal rate was-29%~66%,NH3-N was-55%~33%,TN was-45%~69%,TP was-80%~66%.It was shown that the hydrolysis and acidification of organic matters in mixed urban sewage could be realized by the combined pretreatment process. |
