  • 摘要: 针对印染废水二级生化出水水质难降解且难以达标的现状,研究在不调节pH的前提下,采用铁碳微电解混凝工艺进行处理研究。通过单因素实验确定最优条件范围,建立响应面(response surface methods, RSM)分析实验,确定铁碳微电解的最佳工艺条件为:Fe的投量为72.1 g/L、m(C):m(Fe)为2.98:1、水力停留时间(HRT)为2.6 h。最佳混凝条件为:Al2(SO4)3投量为100 mg/L、混凝沉淀时间为30 min。实验结果表明,在上述最优工艺条件下对该废水进行深度处理,对COD的去除率能达到50%以上,出水COD低至46.1 mg/L,达到提标后的《纺织染整工业水污染物排放标准》新标准(COD≤60 mg/L),其药剂处理成本为每吨印染废水0.355元左右,该法技术可行、经济合理。
    Abstract: As dyeing wastewater secondary biochemical effluent is refractory and cannot satisfy current discharge standards, iron-carbon (Fe-C) micro-electrolysis combined with coagulation was adopted for advanced treatment of dyeing wastewater without a pH adjustment. According to the experiment with a single factor, the range of best reaction conditions was found, then response surface methodology (RSM) revealed that the optimum conditions of Fe-C micro-electrolysis reactions were as follows: the iron dosage of 72.1 g/L, m(C):m(Fe) of 2.98:1, and the reaction time of 2.6 h. In the coagulation process, the aluminum sulfate (Al2(SO4)3) dosage was 100 mg/L, and the coagulation sedimentation time was 30 min. Under the above operation conditions, the removal efficiency of chemical oxygen demand (COD) reached more than 50%, with COD of effluent at 46.1 mg/L, which achieved the new Wastewater Pollutants Discharge Standard for Textile Printing Industry (COD≤6 0 mg/L). The cost of the reagent is 0.355 yuan per ton of dyeing wastewater. This process is feasible and reasonably priced.
