基于产排污系数的木材工业排污量估算及污染负荷研究

Research on Wood Industrial Discharge Capacity Estimation and Pollution Load Based on Generation and Discharge Coefficient

以我国2011年污染源普查得到的产排污系数测算值和企业提供的离线监测数据为依据,对我国木材工业主要污染指标产排量系数进行对比分析;并结合我国近5年木材工业产品的产量,完成基于产排污系数的木材工业排污量核算及污染负荷评估。结果显示:1)我国木材工业产品污染物指标中,工业废气量和工业废水量的产排量比值大,污染控制效率低,而固体污染物排放率为零,处理效果好;2)不同产品排放的污染物在不同年度的排放量和污染程度为纤维板的工业粉尘及废气排放量最大,胶合板的工业废水排放量最大,刨花板污染程度相对较小;污染物中,工业废水排放量近5年增长最快,平均增加5倍以上;3)得出人造板行业与其他工业行业对比性实证数据,为人造板行业立身绿色环保产品提供佐证;4)通过对我国与发达国家污染物指标对比分析,为木材工业节能减排标准的制定及实现低碳发展提供依据。

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.
