| 摘 要： | 固液分离过程中澄清与浓缩的两难问题由来已久．本文讨论了在使用高分子絮凝剂保证澄清效果的前提下如何提高浓缩产物的固体含量，同时设法改善浓缩物的性质使之便于进一步压缩处理的有关问题．文中论述了相关的研究结果、研究方法及潜在的研究方向．分析了聚集体尤其是絮凝体内液体介质的赋存状态，提出了改进絮凝物脱水的某些新机制．

A primary analysis of the dilemma of concentration and clarification |
| |
| Abstract: | For a long time there has been a dilemma of concentration and clarification in the process of seperating solid from liquid. This paper discusses the ways to increase the solid contents of concentrated products and improve the nature of concentrates to facilitate the pressing process at the prerequisite of keeping good clarification. The paper also discusses some relevant research results,approaches and potential tendency, analyzes the existence situations of liquid medium in aggregates especially in floes, and presents some new mechanisms about the floc dewatering. |
