Van-Chi Dao, Xuan-Nam Bui, Tien-Dung Le, Xuan-Ha Tran

The paper presents a new national technical regulation for coal mine wastewater in Vietnam. The analyses of wastewater samples collected at sites indicate that wastewater from Vietnam coal mines is in general low in pH and contains heavy metals such as iron and manganese. Since Vietnam coal industry is being regulated by National Technical Regulation on Industrial Wastewater QCVN 40:2011/BTNMT with 33 parameters, this paper proposes a new National Technical Regulation on Coal Mine Wastewater that includes pH, Total Suspended Solid, Chemical Oxygen Demand, Biochemical Oxygen Demand, iron and manganese whose values are equal to those regulated in QCVN 40:2011/BTNMT.
