|
摘要
本文详细介绍了煤化工废水的特性,并分别从预处理技术、生物处理技术、深度处理技术和组合工艺展开论述,综述了国内外处理技术的研究现状,叙述了各种工艺过程中有毒和难降解污染物的降解机理,列举了各处理技术所遇到的难题。分析总结得出:探索一套完整、先进的煤化工处理技术,降低对活性污泥的抑制作用、实现污泥减量是未来煤化工废水处理研究趋势。
The characteristics of coal chemical wastewater were introduced in details in the paper.The research status of demestic and foreign processing technologies were reviewed,whose techonogies mainly included pretreatment,biological treatment,advanced treatment and combined process.Both the degradation mechanism of toxic and refractory pollutants in various processes and the problems encountered in each treatment technology were described and listed.The conclusions showed that a complete and advanced coal chemical wastewater treatment technology was developed,which can reduce the inhibition of activated sludge.The future research of coal chemical wastewater treatment will decrease the amount of activated sludge.Wastewater is a massive resource.If it is treated economically and effectively,it will realize the recycling of coal chemical wastewater.
