Improvement methods of mining enterprises wastewater purification from nitrogen compounds

A typical negative impact on water resources for mining companies engaged in blasting operations is the discharge of quarry and mine contaminated with nitrogen compounds. The solution problem under consideration assumed an integrated approach based use partially flooded abandoned workings already available at enterprise as bioengineered structures. article substantiates confirms possibility using open-pit treatment wastewater from mines quarries compounds most environmentally hazardous components by natural microbiological nitrification. advantages disadvantages applied cleaning methods are investigated. applying method biological purification waste existing ecosystem justified point view economic efficiency. this described effectiveness its application confirmed.
