Study on mechanisms of treating mine wastewater by goaf and the methods of recycling mine wastewater in Jining No.2 coal mine

The characteristic of coal mine wastewater was introduced. Engineering design and practical run of circulator clarifier +gravity valve-less were summed up for treating wastewater of coal mine. Practice indicated that the process was steady and reliable, the effluent satisfied water quality Ⅲ standard of Surface Water Environmental Quality Standard (GB3838-2002),and there was remarkable economic results during the process of sewage treatment.

Wastewater Quality

The pH index of Trang Bach coal mine wastewater ranges from 2,8 to 6, meanwhile, the content of Fe, Mn, and turbidity & suspendedsolids (TSS) are rather high and it is impossible to discharge the wastewater directly to the environment. In order to achievethe requirement of QCVN 40:2011/BTNMT standard – The national standard for industrial wastewater quality after treatment ofVietnam and other purposes, the wastewater need to be treated by several methods such as coagulation-flocculation or sedimentation.In this article, we intend to find the optimal dosages of chemical compounds for the TSS, pH, Fe and Mn treatment processfor Trang Bach coal mine wastewater in the laboratory modular.
