工业污染源产排污系数编码方法与应用

Coding method and application of pollutant generation and discharge coefficients of industrial pollution sources

编码是将文字信息转换为计算机编程代码的重要工具。为进一步推进工业污染源产排污系数信息化应用,以2017年版产排污系数为核心,根据产排污系数结构及表达方式,建立工业污染源产排污系数编码体系,分别对产污系数和排放量核算参数两部分进行编码。产污系数编码是对表征产污系数的关键因素进行编码,包括行业类型、产污工段、产品、原料、工艺、规模、污染物种类等。排放量核算参数编码是对污染治理技术和治理设施运行效率分别进行编码。再根据各项关键因素的特征、包含信息种类数以及预留一定开发空间等条件,设定编码组成和位数,建立编码方案,并以“3825光伏设备及元器件制造行业”为例进行编码方案应用。产污系数编码为22位,排放量核算参数编码为28位或更多位。产排污系数编码体系的建立为搭建产排污系数信息平台,支撑系数持续更新完善,实现应用于更多环境管理系统提供直接技术支撑。

Encoding is an important tool to convert text information into computer programming code.For the wide application of coefficients,the coding method for converting the production and discharge coefficients into numeric and letter codes has been established.Based on the expression of generation and discharge coefficients of 2017 edition,the pollutant generation coefficients and discharge accounting parameters were coded respectively.The main factors determined the coding structures and contents of the pollutant generation coefficients,including industries,pollution generation sections,products,raw materials,processes,scales and pollutant types.The coding of emission accounting parameters was separately coded by the pollution treatment technology and the operation efficiency of treatment facilities.According to the types and characteristics of various key factors,the code rules and the number of digits were formulated,and the coding scheme was applied using the"3825 photovoltaic equipment and components manufacturing industry"as an example.The pollution coefficient coding was 22-bit coding,and emission accounting parameter coding was 28-bit or more coding.This coding method will provide direct support for the establishment of the information platform for pollution production and emissions coefficients,the continuous updating of coefficients,and the application to more environmental management systems.
