污水处理的新技术与新发展

介绍我国对水污染控制认识的发展和深化，阐述了污水生物处理方面的研究和新进展，包括在微生物方面的研究和新反应器、新工艺的发展。同时，讨论了新型、高效化学混凝剂和絮凝剂的开发成功，使化学法用于城市污水的处理成为可能。并提出任何一种新的处理工艺和反应器都各有其优缺点和适用条件，不能认为某一种就是最好，最先进的，可以无条件适用各种情况的。

New Technology and Progress in Wastewater Treatment

Introduction on deepening cognition and development of knowledge in water pollution control and illustration of research and progress in wastewater biological treatment, including microbiology and development of new reactors and new processes were presented. Discussion on successful development of highly effective new-type coagulant and flocculent which made them possible to apply chemical processes to urban wastewater treatment were also presented. But it is not right to consider which types are the best, most advance or applicable to any circumstances without preconditions.
