【摘要】 混凝是一个恒久的话题,一个引人入胜的课题,一个亟待解决的难题.水质的急剧恶化与科学技术的日趋发展,对混凝研究提出了严峻的挑战,而同时也给研究以一定的发展机遇.在简略地回顾混凝研究历史的基础上,对水体颗粒物、无机高分子絮凝剂、混凝作用机理以及混凝工艺研究的进展进行了概括性介绍.重点论述了强化混凝/优化混凝的必要性与目标.并进一步对若干主要研究进展与发展方向加以评述.更多还原

【Abstract】 Coagulation is a subject of long history, a topic full of interesting, and a problem urgently needs to be solved. The rapidly deteriorated water quality and developed technology put forward great challenge to coagulation and possible chance to some extent as well. In this paper, the history of coagulation has been addressed first briefly. The current situation in the research on the aquatic particles, inorganic polymer flocculants and mechanism, and coagulation technology are reviewed. Specific attention has been paid on the necessity and direction of enhanced coagulation and optimised coagulation.更多还原
