Abstract:

Pollutants index evaluation and accounting,which is important scientific basis to environmental protection standards and environmental construction. For many years, research on discharge estimation and the corresponding index work in wood industrial pollutant that had been few in China, and brought the difficulty to industry environmental standards and industry policy. According to coefficient calculation in yield emission and the enterprise provided the off-line monitoring data on the basis of the wood industry in our country in 2011, combined with wood industrial product yield in nearly five years, completed emission coefficient of wood industry amount accounting and pollution load evaluation. The results showed that: 1)Wood industry product pollutants index, the scale was relatively large between industrial waste gas and waste water, pollution efficiency was minimum, solid pollutant emission rate to zero, the treatment effect was better. 2)The discharge of different pollutants in annual emissions and pollution degree, industrial dust and gas emissions maximum for fiberboard; industrial wastewater emission maximum for plywood; particle board pollution level relatively small; the average increased more than 5 times in nearly five years. 3)Data of man-made board industry and other industry comparative empirical, showed the man-made board industry had been the green industrialization. 4)Through analyzed pollutants index and compared with our country and the developed countries,which would provide basis of the energy wood industry standards in energy conservation and emission reduction, and achieved a low carbon development.
