含氰污泥处理的研究

就逆流洗涤和洗涤投药两种工艺进行试验研究,结果表明采用逆流洗涤的方法,能降低污泥中的氰化物,浓度可达标,但是存在不少缺点。而采用洗涤投药工艺,不但可以使污泥达标,更重要的是技术上可行,经济上也比较合理。

The Study of Cyanide - bearing Sludge Treatnent

This paper experimentally studied two kinds of technology, adverse current wash and wash with adding chemical agent. A large number of experiment showed that the cyanide content in the sludge can be reduced by adverse current wash,and cyanide concentration in the sludge is less than the stipulated value,but there are some defects in adverse current wash. However,cyanide concentration in the sludge can be less than the stipulated value by wash with adding chemical agent ,and its technology is feasible and economy is reasonable comparably.
