污染水源水的生物预处理

传统的水处理工艺，在处理污染源水时，所提供的自来水水质已不能满足要求，其工艺改革势在必行。根据近年来国内在污染源水的生物预处理方面取得的成果，通过比较、分析，指出传统工艺的不足之处及生物法预处理的优点，并展望了其应用前景。分析结论是，污染源水的生物法预处理是一种经济有效且无副作用的方法，其本质是水体天然自净过程的人工化，对ＮＨ３－Ｎ、酚和有机物，具有较满意的去除效率。

Biological Pretreatment of Polluted Source Water

It is recognized at present that the water quality of drinking water can't meet the demands if the water is polluted and only treated by traditional process, so that the reform is needed. According to the recent domestic achivement in biological pretreatment of polluted source water, the shortage of traditional technology has been analyzed and the virtue of biological pretreatment expressed by comparing with the traditional one. It showed that biological pretreatment of polluted source water was effective and without side-effect specially in removing ammonia nitrogen, phenol and organic contaminants.
