PCB industry is one of the six strategic emerging industries in tongling city.Some waste water will be produced in the process of PCB electroplating.For a single enterprise, the waste water that needs to be treated includes six kinds of waste water, such as acid, alkali, organic and nickel. The construction investment and daily operation cost of waste water treatment facilities are huge.For this reason, tongling PCB industrial park adopted the BT model and constructed the sewage treatment plant of the environmental protection center of the industrial park as a supporting part of the park. Currently, tongling jindalai environmental protection technology co., ltd. is commissioned to operate the PCB sewage treatment."Industrial wastewater treated with biochemical and physical-chemical processes has a PH of 7, chemical oxygen demand of 60 milligrams per liter and copper ions of 0.2 milligrams per liter.The discharge of industrial waste water after treatment can meet the discharge standard of electroplating wastewater in the industry.Tongling jindalai environmental technology co., LTD. General manager wang lijun said.
It is reported that in December 2010, tongling was built and put into operation by PCB sewage treatment plant in tongling development area, with a daily capacity of 1200 cubic meters.The third-party treatment of environmental pollution implemented by tongling economic development zone not only reduces the cost of pollution control for polluting enterprises, but also improves the standard emission rate.At the same time, it also stimulated the development of environmental protection enterprises and industries.At present, six enterprises, such as lekate technology, jinsai technology, ambow technology and Emerson electric, have concentrated their waste water treatment by PCB sewage treatment plant.
