摘　　要：针对印染工业废水中的苯、萘、蒽醌类有机物、芳族硝基化合物、芳族胺类化合物等对活性污泥的抑制作用,以及印染工业废水水质水量变化大、生化性较差、处理难度大的特点,通过改良芬顿催化氧化工艺技术的中试研究,获取相关的设计参数及数据,确定了该工程污水处理采用水质水量水温及pH调节+水解酸化+AO生化反应+改良芬顿催化氧化工艺的技术路线。结果表明,工艺可使尾水达到《纺织染整工业水污染物排放标准》(GB 4287—2012)中表2直接排放标准。同时,针对本项目用地狭小的条件,结合工艺流程对各工艺单元在平面上优化组合、空间上叠层布置,实现了处理单元集约化、土地高效利用的最大化。In view of the inhibition of benzene,naphthalene,anthraquinone organics,aromatic nitro compounds and aromatic amines in printing and dyeing industrial wastewater on activated sludge,as well as the characteristics of large changes in water quality and quantity,poor biochemistry and difficult treatment of printing and dyeing industrial wastewater,combined with the water quality analysis of pilot test of improved Fenton catalytic oxidation,this project has selected the pH regulation+hydrolytic acidification+AO Biological reaction+improved Fenton catalytic oxidation process technology.Results showed that,the final effluent quality of pollutants can meet table two specified in Discharge Standards of Water Pollutants for Dyeing and Finishing of Textile Industry(GB 4287—2012).At the same time,according to the condition of narrow land use,the plane optimization combination and spatial stacking layout of each process unit are carried out to realize the intensification of structures and maximization of land use efficient.
