摘要

为混凝技术在洗浴废水回用中更好地应用

采用了正交试验的方法.结果表明

对于试验研究废水

混凝技术的最佳反应条件为:PAC与PAM量投分别为180 m g/L和12.5 m g/L

pH值8.5

300 r.m i-n 1快速搅拌2.5 m in

45 r.m in-1慢速搅拌15 m in

静沉10 m in;影响因子相对重要性的大小次序为:PAC投量pH值慢速搅拌时间慢速搅拌速度PAM投量静沉时间快速搅拌速度快速搅拌时间.单独使用混凝技术处理洗浴废水

出水水质可满足生活杂用水水质标准.

Abstract

The feasibility and impact factors of flocculation used to treat bathing wastewater from northwestern polythenical university were studied by the orthogonal experiments to improve the technology in bathing wastewater reuse.The results showed that

to treat the studied wastewater by the flocculation

the best operating conditions determined by the orthogonal experiments were the dosages of 180 mg/L and 12.5 mg/L for PAC and PAM

8.5 pH

300 r·min~-1 for 2.5 min

45 r·min~-1 for 15 min

10 min setting time;and the order for the factors in the relative value was gotten by variance analysis: the dosage of PACpH slow speed stirring time stir with slow speed the dosage of PAMsettling time stir with acute speed acute speed stirring time.Bathing wastewater treated by the flocculation under these optimum conditions is satisfied with the criterions of afforest and toilet water.
