March 26, the State Department of Environmental Protection investigation team, accompanied by the city and county of relevant departments, to research car River Concentrator "Beneficiation Wastewater treatment and reuse project," the operation and management.

Research group deep into the plant beneficiation wastewater treatment plant, toured the "beneficiation wastewater treatment and reuse project," the operation, a detailed understanding of the "beneficiation wastewater treatment and reuse project," the operation, the daily management introduction.

Car River concentrator beneficiation wastewater treatment project is "2010 the first national heavy metal pollution prevention projects of special funds - car River concentrator beneficiation wastewater treatment and reuse project construction" under the demonstration project, designed by the Beijing General Research Institute of Mining and Metallurgy , in October 2011 to start the construction, completed in August 2012 began to run the debugger, March 15, 2013 through the completion of environmental acceptance and formally put into use. The project uses water quality "mechanical filtration and heavy metal (special resin) + arsenic adsorption (special resin) adsorption" method depth treatment I plant tailings overflow outlet, designed to handle the amount of water Q = 1200m3 / d (50m3 / h), water arsenic, cadmium, lead, zinc, copper and other indicators to achieve stability, "Surface Water Environmental Quality Standard" (GB3838-2002) Ⅲ type water standards. The project depth beneficiation wastewater treatment can significantly reduce our plant into heavy metal and arsenic and other pollutants in surface water bodies, good effect, low operating cost, with higher environmental benefits for the non-ferrous metal industry heavy metal pollution provide a model .

Research group related presentations by listening and field after viewing the car select "beneficiation wastewater treatment works and reuse" of the operation and management, etc. to give a high praise, think beneficiation plant wastewater treatment plant daily management of the foundation is solid, safety regulation in place, safety features in place, the ledger records norms, but hoped the plant to continue to strengthen the daily supervision, especially during the rainy season to strengthen the management, good safety in flood protection work.
