为考察固定三维电极法处理餐饮废水的效果,使固定三维电极法与二维电极法在相同实验条件下处理餐饮废水﹒单因素实验结果表明固定三维电极法对NH3-N、CODcr和SS的去除率均较高﹒通过正交实验,确定各影响因素对处理效果的影响顺序为:活性炭投加量>废水初始pH>电解时间>电流密度;最佳实验条件为:活性炭投加量为30 g?L-1,电流密度为50 m A?cm-2,废水初始pH为6,电解时间为40 min﹒在最佳实验条件下,NH3-N去除率为51.92%,CODcr去除率为81.90%,SS去除率为88.76%﹒

In order to investigate the treatment efficiency of restaurant wastewater by using fixed three-dimensional electrode method, restaurant wastewater is disposed under the same experimental conditions between the fixed three-dimensional electrode method and two dimensional electrode method. The single factor experimental results show that the removal rates of NH3-N, CODcrand SS are higher by using fixed three-dimensional electrode method. The priority of influential factors are confirmed by orthogonal experiment as follows: the activated carbon dosage > wastewater initial pH > electrolysis time >...
