焦化

This Waste water containing tar, phenol, ammonia, cyanide, benzene, pyridine, quinoline and indole dozens of other pollutants, it is very complex and is high concentrations of pollutants, it is color, toxicity and stable, after biological treatment,there are still a large number of non-degradable organic pollutants, it is a typical example of intractable industrial wastewater.

焦化废水是煤在高温干馏过程中以及煤气净化、化学产品精制过程中形成的废水，其中含有焦油、酚、氨氮、氰、苯、吡啶、吲哚和喹啉等几十种污染物，其水量大，成分复杂，污染物浓度高、色度高、毒性大，性质稳定，经生化处理后，仍有大量难降解的有机污染物，是一种典型难处理的工业废水。
