Investigation of Heavy Metals Containing Acidic Waste Waters from Coal Mine

摘要: Waste water from ore plant layout central Alborz's coal has been investigated and analyzed. Studies showed that because of acidic character, the waste contains heavy metals including Cu, Cr, Ba, Zn, V, Sr, Pb, Ni. Considering importance this topic for outgoing waters which is hazardous environment, i.e. metals, same should not be transferred into environment. Since their nearby agricultural ground, it was developed a method, so primarily directed slug pond sedimentation. In second stage in another pond, outflow treated with chemicals. Also pH controlled, are separated. Also, neutralized. The then filtered by filter press precipitation removed. All precipitations were separated manner eventually environmental problem solved.
