摘要

高盐废水中有机物的脱除一直是水处理领域中研究的热点和难点,以某海滨电厂脱硫废水为研究对象,以复合氧化物作为催化剂,利用类芬顿法降解高盐脱硫废水中的有机物。考察在多种实验条件下,不同过氧化氢加入量,不同废水初始p H值,不同反应时间对出水总有机碳(TOC)的去除影响情况。研究结果表明,废水处理的最佳条件为:过氧化氢加入量0.75×10-2m L/m L,反应时间2 h,初始p H值为8.1,废水的TOC去除率可以达到77.4%,出水澄清透明。复合氧化物催化剂的加入,极大地提高了过氧化氢的利用效率,并且催化剂具有制备成本低,稳定性高等优点,极大地提高了水处理效率并节约了废水处理的成本。
        Removal of organic matters from wastewater with high salt concentration is always the research hotspot and difficulty in water treatment area. The desulfurization waste water from coast power plant is regarded as the research object,and the multiple oxide is regarded as catalyst. The organic matters could be removed from the wastewater through Fenton-like process. Several parameters for experiment have been investigated: H2O2 dosage,initial p H value and reaction time,which could influence the TOC removal. The result showed that,the optimal treatment conditions for wastewater were as below: the H2O2 dosage was 0. 75 m L/100 m L,the reaction time was2 h and the initial p H was 8. 1. The TOC removal rate could reach 77. 4% and the clear effluent could be obtained. As the addition of the multiple oxide catalyst,the utilization efficiency of H2O2 could be improved,meanwhile,the catalyst showed the advantage of low cost and high stability,which could promote the water treatment efficiency and save the water treatment cost.
