活性污泥
活性污泥
相对于传统普通活性污泥法,膜生物反应器由于膜的截留作用,实现污泥龄和水力停留时间的彻底分离。
The preparation of red cement using activated red mud stone has been studied.介绍利用活化红泥岩制备红色水泥的研究。
The results show that among the three kinds of seeds, the activated red mud has the best desilication effect and the silicon index of desilication solution can meet the requirement.试验表明:活化赤泥的脱硅效果优于拜耳法末次赤泥及溶出赤泥,且脱硅溶液硅量指数可达到指标要求。
