基于水资源消耗和CODCr排放双调控的我国工业分类研究

从水资源消耗和COD_Cr排放双调控出发，利用2005年各工业部门有关统计数据，基于万元产值水资源消耗和COD_Cr排放强度，将40个工业部门划分为低水资源消耗-低污染工业、高水资源消耗-低污染工业和高水资源消耗-高污染工业3类.基于该分类方案，利用2001—2005年统计数据，对3类工业水资源消耗和COD_Cr排放进行统计分析，结果表明:占工业生产总值30%的高水资源消耗-高污染工业，排放了接近85%的COD_Cr有机物；占工业生产总值40%的高水资源消耗-低污染工业，水资源消耗接近75%；而占工业生产总值30%的低水资源消耗-低污染工业，水资源消耗不到2%，COD_Cr的排放量也低于4%.基于该工业分类方案，建立起工业生产与水资源消耗量和COD_Cr排放量之间的双向联系. 

A Study of Industrial Classification Based on the Double Regulation of Water Consumption and CODCr Discharge in China

Based on the data of different industrial departments in 2005, the forty industrial sub-sectors were re-classified, embarking on the water consumption and COD_Cr discharge double regulation. The results show that they can be divided into three types based on the water consumption and COD_Cr discharge per tenthousand RMB Yuan. One is low water consumption and low pollution, the second ishigh water consumption and low pollution, and the third is high water consumption and high pollution. According to the new industrial classification, the waterconsumption and COD_Cr discharge of the three-type industry were analyzedusing the data of 2001—2005. The results are follows: the high water consumption and high pollution industries produce 30% of total output value and discharge 85% of the total COD_Cr; the high water consumption and low pollution industries produce 40% of the total output value and consumes 75% of the total water;the low water consumption and low pollution industries produce 30% of total output value, consume 2% of the total water, and discharge less than 4% of the total COD_Cr. The new industrial classification builds double relation between industrial production and water consumption and COD_Cr discharge, thus providing a scientific basis for constructing the resource-conservation and environmentally-friendly society.
