摘要
文章分析了使用化学强化一级除磷技术存在的主要问题,特别指出了化学絮凝剂在生产过程中存在的消耗人类有限资源及环境污染大等缺点,认为该种除磷方法不符合可持续发展的理念。生物除磷技术因操作方便及二次污染小等特点成为近年来国内外研究的热点。文章通过介绍生物除磷技术的微生物学、除磷效率等领域的研究进展,结合本课题组取得的部分结果,认为科研工作者应重视该技术的应用基础研究并在实际生产中加以推广应用。
Based on the analysis of main problem of chemically enhanced primary treatment (CEPT), it was concluded that CEPT does not satisfy sustainable development due to contamination to the environment. Enhanced biological phosphorus removal (EBPR) is becoming more and more popular because of its convenient operation and less pollution. Microbiology and efficiency of phosphorus removal of EBPR were introduced, and it was proposed that more attentions should be paid on EBPR.
