the wastewater collected at each produce stage discharge into exterior drainage after treated. although the cod, nh3-n, tn, total cyanide index is relatively low, the water cannot meet the requirement of direct emission. wastewater from the steel park is characterized as great fluctuation in quantity and quality. our company develop a comprehensive solution, by which it is realized that cod<30 mg/l, nh3-n<5 mg/l, tn<15 mg/l, total cyanide index<0.2 mg/l, meeting the standard in steel industry (gb 123456-2012).
