化学工业园区重大环境风险源监控技术研究与应用

Study and Application of Major Environmental Risk Source Monitoring Technologies within Chemical Industrial Park

基于监控系统综合集成的思想,以重大环境污染事件风险源监控技术规范、重大危险源控制规章、污染源在线监测为基础,从监控指标体系、监控布点范围及监控技术筛选三方面建立化学工业园区中重大环境风险源监控技术体系.结果表明:重大环境风险源监控指标体系主要从企业内部及企业周边敏感受体两方面进行构建;监控范围从重大环境风险源本体、缓冲区及环境敏感受体三方面确定;监控技术筛选时考虑了环境风险源的状态、监控技术方法的实用性和环境风险源受体属性.以上海闵行区化学工业园区为例,经调研统计,该化学工业园区共有重大风险源87个,其中罐区60个、排放口12个,其余分散在库房、生产场所等处.根据化学工业园区企业内部风险设施及周围敏感受体的监控指标、监控范围及常用监控技术,制定了以罐区、排放口的特征风险物质为指标,以储罐的温度、压力、图像视频、液位及排放口特征风险物质浓度的传感器监控技术为主的监控方案.

Based on the concept of monitoring system integration, monitoring technical specification for risk source, major hazard control, and on line monitoring of pollution source, a monitoring technology system of chemical industrial park （CIP） is promoted. The indicators, sites range and technologies of risk source monitoring are comprehensively considered in this system. The results showed that the construction of monitoring indicator system mainly considered enterprise＇ s internal and environmental sensitive receptors. The monitoring range should be determined from the major environmental risk source, buffer zone and environmental sensitive receptors. The monitoring technology should be selected according to the status of environmental risk source, the practical of monitoring method and the properties of environmental risk source/receptor. Finally, Minhang District of Shanghai City is taken as a case tbr study. There are 87 major risk sources including 60 tank, 12 outfall, the rest scattered in the storehouse, production sites, etc by investigating and sampling. Take indicators, site range and monitoring technologies of risk source in enterprise＇ s internal and external sensitive receptors as research object, the monitoring programs are established for major environmental risk source in Minhang CIP. Which take the concentrations of tank and outfall as monitoring indicator, and take sensor for monitoring the tank temperature, pressure, video, level, and concentration of risk substance for monitoring instrument.
