受污染水体的生物强化过滤研究

[目的]以受污染水为水源,对生物强化过滤工艺与常规净水工艺处理微污染水源水进行对比研究。[方法]对处理后的水质进行CODMn、NH4＋-N、色度、浊度等指标分析,计算出常规工艺去除率和生物强化去除率。[结果]生物强化过滤工艺对受污染水源水中污染物的去除效果明显优于常规净水系统,其对CODMn、NH4＋-N、色度、浊度的去除率分别为34%~56%、78.7%~92%、53%~68%、90%;而常规净水工艺对CODMn、NH4＋-N、色度、浊度的去除率仅为11%~30%、4.7%~25%、38%~54%、60%~80%,并且处理效果不稳定。[结论]采用生物强化处理系统处理微污染水源水具有较强的针对性和可行性。

Reseach on Contaminated Source Water Treatment by Enhanced Biological Filtration

[Objective] This paper compared enhanced biological filtration system with conventional water treatment,taking contaminated source water as source water.[Method] CODMn、NH+4-N、chromaticity and turbidity of treated water were analyzed,the removal rate of conventional technology and enhanced biological filtration system were calculated.[Result] Enhanced biological filtration system was excelled to conventional water treatment,the removal rates of CODMn、NH+4-N、chromaticity and turbidity were 34%-56%、78.7%-92%、53%-68%、90% by enhanced biological filtration system;however,the removal rates of CODMn、NH+4-N、chromaticity and turbidity were only 11%-30%、4.7%-25%、38%-54%、60%-80% by the conventional water treatment and the remval effection was instability.[Conclusion] Enhanced biological filtration system has strong pertinency and feasibilty in the micro-polluted source water.
