工业废水排放的影响因素量化分析

工业废水排放量的大小受工业发展水平、产业结构、产品结构、技术工艺及设备水平、管理政策、环境法规等多因素的综合影响。选取长江三角洲典型地区的主要污染排放指标，重点分析工业经济规模、工业行业结构、工业技术进步以及环境治理投资等因素与工业水污染排放之间的相互关系。研究结果表明：随着长江三角洲地区产业结构的调整、工业技术进步、工业废水达标排放政策的实施，工业规模的扩大并没有引起工业废水的显著增加。从制造业结构看，有些行业的废水排放量对其结构调整比较敏感; 相反，有些行业的废水排放量对其结构的调整不敏感。工业技术进步和环境治理投资与工业废水排放量呈现负相关，说明工业技术进步、环境污染治理对于减少工业水污染排放起重要作用。

QUANTITATIVE ANALYSIS ON THE INFLUENTIAL FACTORS OF INDUASTRIAL WASTE DRAINAGE

The waste drainage of industry is affected by its scale,structure,composition,technology and \{equipments\} ,as well as the environmental management and policy. This article selected some key indexes in water pollution and analyzed the relationship between the scale,structure,technology of industry,as well as the investment of environmental management. It is showed by this study that the enlargement of industrial scale has not caused the increase of waste industrial drainage,with the adjustment of industrial structure,the improvement of technology and implementation of standard drainage policy in the Yangtze River Delta. As to the industrial structure,some industrial drainage are sensitive to adjustment of their structure,but others are not. The improvement of industrial technology and investment of pollution control have negative relationship with industrial waste drainage,which means that the improvement of industrial technology and pollution control play an important role in the decrease of industrial water pollution.
