摘要
分析了闭路循环工艺中各种成分的积累规律，探讨了无限封闭循环的条件和闭路循环工艺建立的基本规律，提供了两个运用闭路循环工艺治理工业废水的案例．
Circulation process of materials around circuit is always one of the most important parts in clean production. The principles for accumulation of various components in circulation and the conditions for establishing infinite circulation were analyzed in the paper. A mathematical model of circulation process was established and two examples of industrial waste water treatment in which circulation process of materials around circuit was used were also shown in the paper.
