BIOTREATMENT OF POLLUTED WATER -VIS-A-VIS-SOCIO-ECONOMIC DEVELOPMENT IN COAL MINING AREA

Abstract

Coal being a primary source of energy, plays a vital role in an energy-intensive economy situation such as prevailing in India. Irrespective of the mining methods employed, mining is bound to cause various environmental problems and one of them is water pollution. Many problems related with water is scarcity, contamination and storage due to disturbance of groundwater aquifer by opencast coal mining. Coal mining and other related industries discharges water into river, streams and nallahs which goes as waste without any fruitful utilization. When this water drains through a large area of the mine it carries with it many soluble minerals that may present either in the coal or associated rocks, thus causing degradation of water quality. Besides this, sewage and industrial effluents water are also present in coal mining areas. Mechanical, chemical and other treatment methods for the sewage, mine and industrial effluents water found costlier. There is a bio-treatment option to recycle this polluted water for some useful purposes. This will not only save money & energy but also help in the upliftment of socio-economic status of the poor people living nearby. This paper discusses the concept and prospects of technology to be developed out of this approach.
