| 摘 要： | 针对气提式接触氧化法处理生活污水处理效果的影响因素,在实验室条件下,以某中学学生住宿区的生活污水为原水,结合概率与统计学中的正交试验原理,分析论证了水温,气水比,水力负荷对考察指标COD去除率的影响显著性。结果表明,水温在20℃时,处理效果相对较好,最佳气水比和水力负荷分别为16∶1和5.0 m3/d,COD和氨氮平均去除率分别为80%和56%,且出水COD、氨氮等指标均达到了城市杂用水水质标准的要求。

| Abstract: | Pointing to the affecting factors of air-lift contact oxidation method on domestic sewage treatment,under laboratory conditions,taking the domestic sewage in a middle school’s student area for example,and combining with the orthogonal experiment principles in probability and statistics,the affecting significance of the water temperature,gas-water ratio and hydraulic load on COD removal efficiency of the indexes is analyzed and appraised here in detail.The results show that when the water temperature is at 20℃,the treatment effect is relatively good,the best gas-water ratio is 16∶1,the hydraulic load is 5.0 m3/d,COD and ammonia nitrogen removal rate are 80% and 56% respectively,and the effluent COD,ammonia nitrogen and other indicators have reached the miscellaneous water quality standards in cities. |
