摘要：

近年来，随着煤化工行业不断发展，废水排放量加大。煤化工行业废水排放量大、高盐和高化学需氧量的现状使得对其的处理成为一大热点和难点。本文以伊犁某工厂实际含盐有机废水（TDS含量25000mg/L）成分为依据，选取2-甲氧基苯酚作为煤化工废水中典型有机物，采用电化学协同过硫酸盐法处理含盐有机废水，主要考察电压、初始过硫酸钠浓度、极板间距及初始pH对2-甲氧基苯酚降解率的影响。结果表明，综合考虑电能消耗及氧化剂成本，在2V电压、极板间距3cm、过硫酸钠投加量5g/L、pH=12以及反应3h条件下，2-甲氧基苯酚的降解率可达到97.5%，相较单一的电化学法或过硫酸盐氧化法均有显著提升，协同效应明显。本文研究结果为今后煤化工行业含盐有机废水的绿色高效处理提供了一种新的思路。

Abstract:

In recent years, the discharge of wastewater has increased with the continuous development of coal chemical industry. Wastewater treatment has become a hot and difficult spot for the large emissions, high salt and high COD. Based on the actual ingredients of the salty organic wastewater (TDS content is 25000mg/L) from a plant located in Yili (Sinkiang), 2-methoxyphenol was chosen as a typical organic in coal chemical wastewater. The method of electrochemistry synergistic persulfate oxidation was investigated to degrade 2-methoxyphenol. The influence of voltage, initial concentration of sodium persulfate, electrode distances and initial pH on the degradation ratio of 2-methoxyphenol were discussed. Considering the electronic consumption and oxidant cost, the suitable degradation conditions of 2-methoxyphenol were the voltage of 2V, electrode distance of 3cm, initial sodium persulfate concentration of 5g/L, pH=12 and reaction time of 3h, and the degradation ratio could reach 97.5%. Compared with the single method of electrochemistry or persulfate oxidation, this method has obvious improvement on the degradation of 2-methoxyphenol and shows a synergistic effect. These results could provide a new method on environmental and efficiency wastewater treatment of coal chemical industry in the future.
