摘要
化工园区事故污水污染成分复杂、生态毒性强、处理要求高。基于应急处理要求,需要快速筛选适用技术。本研究在分析我国近40年化工园区突发水污染事件及事故污水水质特征基础上,介绍了吸附法、高级氧化、化学沉淀、生物降解与组合技术等事故污水应急处理技术,分析了不同技术的作用原理、特点及应用效果,重点阐述了活性炭强化活性污泥技术,系统总结了不同技术的主要工艺、适合处理的目标污染物、优点和不足,以期为化工园区事故污水应急处理技术筛选提供参考和借鉴。
Accident wastewater from chemical industry parks(CIPs)has complex pollution components,high ecological toxicity and high treatment requirements.It is necessary to quickly screen the applicable technologies for responding the emergency requirement.Distribution of sudden water pollution accident and the characteristics of accident wastewater from CIPs were analyzed over the past 40 years of China.Then,emergency treatment technologies including adsorption,advanced oxidation,chemical precipitation,biodegradation and combination technology were mainly summarized;and their functional mechanism,characteristics and application effects were also emphasis introduced.Moreover,the main processes,target pollutants,advantages and disadvantages of different technologies were presented.These results could provide the reference for screening suitable emergency treatment technologies for accident wastewater from CIPs.
