A research on Treating and Recycling Wastewater from Mine Tunnels at 790 Coal Mine, MTV 790 Ltd. Company
Large amount of water is used and wastewater is created in coal mining industry. Coal mining wastewater treatment by reusing it for production and domestic purposes is then essential. Coal pit No 790 of Dong Bac Coal Corporation locates in the area of Mong Duong district, Quang Ninh province. Wastewater after treatment is within the limitation specified in the column B in QCVN 40:2011/BTNMT on industrial wastewater. The process effectiveness of treating turbidity, iron and Mn reaches the maximum level of83%, 30% and 40% (after Arkal filtering disc); 88%, 71% and 87% (after Media Filter); and 57%, 78% and 84% (after UF membrane filter) respectively.Those above indicators have met regulations for domestic water under QCVN 01:2009/BYT. However, the Coliform has insignificantly decreased after treating by Arkal filter which are hundreds to thousands of CFU/100ml. The amount of Coliform have decreased to 12 ÷ 51 CFU/100ml (after Media Filter) and from 1 to 18 CFU/100 ml (after through UF), respectively. The wastewate has been required for further treatment for purpose of domestic water supplying for workers and local people.
