The electrochemical oxidation of simulated textile wastewater was studied on iron electrodes in the presence of NaCl electrolyte in a batch electrochemical reactor. The simulated textile wastewater was prepared from industrial components based on the real mercerized and non-mercerized cotton and viscon process, being first in literature. The highest COD, color and turbidity removals were achieved as 93.9%, 99.5%, and 82.9%, respectively, at 40% pollution load, 8 V applied potential, 37.5 g/L electrolyte concentration and 30 degrees C reaction temperature. The electrochemical treatment of industrial textile wastewater was optimized using response surface methodology (RSM), where applied potential and electrolyte concentration were to be minimized while COD, color and turbidity removal percents were maximized at 100% pollution load. In a specific batch run under the optimum conditions of 30 degrees C reaction temperature, 25 g/L electrolyte concentration and 8 V applied potential applied with 35.5 mA/cm2 current density at 100% pollution load, COD, color and turbidity removals were realized as 61.6%, 99.6% and 66.4%, respectively.
在间歇式电化学反应器中，以铁电极在NaCl电解质存在的条件下，对模拟纺织废水的电化学氧化进行了研究。该模拟纺织废水是基于实际丝光棉和非丝光棉以及粘胶工艺的工业成分制备的，这在文献中尚属首次。在40%的污染负荷、8V的外加电势、37.5g/L的电解质浓度和30℃的反应温度下，COD、色度和浊度的最高去除率分别达到93.9%、99.5%和82.9%。采用响应面法（RSM）对工业纺织废水的电化学处理进行了优化，即在100%污染负荷下，将外加电势和电解质浓度降至最低，同时使COD、色度和浊度去除率最大化。在100%污染负荷下，于30℃的反应温度、25g/L的电解质浓度和8V的外加电势的最佳条件下进行特定的间歇运行，电流密度为35.5mA/cm²，此时COD、色度和浊度的去除率分别为61.6%、99.6%和66.4%。
