- 摘要:
- 为提高三维电解固定床对餐饮废水的处理效果，拟在三维电解固定床中采用不同的阳极板材料（不锈钢板、活性炭纤维毡板和钛极板），对三者处理餐饮废水的效果进行综合比较分析，并选出最佳的阳极板材料。通过单因素实验分别改变活性炭投加量、电流密度、初始pH值和电解时间，比较这3种电极板材料对COD和SS的去除效果。结果表明，综合考虑处理效果和经济性，钛极板最佳，其次是不锈钢板，最后是活性炭纤维毡板。通过正交实验确定各因素对钛极板处理效果的影响程度，并确定其最佳处理条件如下：活性炭投加量为15 g/L，电流密度为50 mA/cm2，初始pH值为3，电解时间为40 min。最佳条件下，三维电解固定床对动植物油、BOD5、COD和SS的去除率分别为99.21%、66.54%、84.21%和90.76%。三维电解固定床的阳极可优先选用钛极板，以期在取得较好处理效果的同时降低成本。
- Abstract:
- In order to improve the treatment efficiency of three-dimensional electrolytic fixed bed treating catering wastewater, different positive plate materials (stainless steel plate, activated carbon fiber plate and titanium plate) were applied in a three-dimensional electrolytic fixed bed. Efficiencies of the three plate materials treating catering wastewater were compared and analyzed comprehensively, and the positive plate material with the best treatment efficiency was selected. By changing the amounts of activated carbon, current density, initial pH and electrolysis time in single-factor experiments, the removal efficiencies of COD and SS were compared among the three plate materials. Considering the treatment efficiency and economy, the titanium plate was the best, followed by the stainless steel plate, and then the activated carbon fiber plate. The influence degree of each factor on the treatment efficiency of titanium plate was determined by orthogonal experiments, and the optimal processing conditions were as follows: dosage of activated carbon was 15 g/L, current density was 50 mA/cm2, initial pH was 3 and electrolysis time was 40 min. Under the optimal experimental conditions, the removal efficiencies of animal and vegetable oils, BOD5, COD and SS were 99.21%, 66.54%, 84.21% and 90.76%, respectively. Therefore, the titanium plate was suggested to be selected as the anode for the three-dimensional electrolytic fixed bed in order to achieve better treatment efficiency and reduce the cost.
