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