印染工业园区污水处理厂深度处理工艺应用综述

Review of Advanced Treatment Technology for Printing and Dyeing Industrial WWTP

文章针对印染工业园区污水处理厂深度处理的对象和目标,结合工程实例和前期相关试验研究成果对深度处理工艺进行对比,分析了臭氧(催化)氧化、芬顿氧化、活性炭吸附、曝气生物滤池(BAF)等深度处理工艺的处理效果及运行成本。工艺效果和经济性分析表明,“臭氧(催化)氧化+BAF”工艺应用最多,活性炭吸附工艺效果有保证但是再生工艺占地大、运行较复杂,芬顿工艺效果好但是药剂种类多、化学污泥产量高、运行成本较高。研究结果可为印染工业园区污水处理厂深度处理工艺选择提供参考。

Aiming at the objects and goals of advanced treatment of printing and dyeing industrial wastewater treatment plants(WWTPs),advanced treatment processes of ozone(catalytic)oxidation,Fenton oxidation,activated carbon adsorption and aeration biological filtration are analyzed in this paper.On the basis of engineering examples and previous relevant experimental research results,the treatment effect and operating cost are analyzed.The process effect and economy analysis show that the"ozone(catalytic)oxidation+BAF"process is the most widely used.The activated carbon adsorption process has a guaranteed effect,but the regeneration process occupies a large area and the operation is complicated.The Fenton process is effective but is associated with many types of chemicals,high production of chemical sludge and high operating costs.The paper can be reference for the advanced treatment process selection of printing and dyeing industrial wastewater treatment plants.
