摘要
PTA生产具有工艺流程复杂,物耗能耗大、副产物多、废水排放量大、水质成分复杂、污染物浓度高等特点,因此,科学的工程分析,可行的环境影响减缓措施在PTA项目环境影响评价中十分重要。本文以某150万t/a PTA项目环评为例,分析和探讨了PTA生产的特点及原辅料使用情况,工程分析的重点和方法,确定水污染因子及产生节点,提出保证水污染物达标排放的防治措施与对策。
The characters of PTA production are complicated process flows and wastewater quality, high concentration of pollutants, by-products, materials and energy consumption and waste water discharge ,which makes the scientific engineering analysis and feasible pollution slow down measures important in the environmental impact assessment. Taking the projects of a 1500 000t/a PTA production as example .this paper discussed the production characters and material using status of the PFA,analyzed the key points and methods of engineering analysis,definited the water pollution factors and production nodes and put forwards the measures to make the wastewater quality meet the discharge standard.
