摘　　要：采用电-Fenton法预处理煤低温干馏兰炭废水,考察了阴极材料、反应时间、反应p H值、电流密度和极板间距对电-Fenton反应的影响。最后选择不锈钢板作为阳极,石墨板作为阴极,最佳试验条件为电反应p H值为4.0,反应时间为150 min,极板间距为3 cm,电流密度为5.0 m A/cm2。在此最佳条件下,CODCr去除率达到57.30%,该方法为治理兰炭废水提供了借鉴思路。Using electro-Fenton process to pretreat semi-coking wastewater from low-temperature carbonization of coal, the influences of cathode material, reaction time, pH value, current density and space between polar plates on the reaction effect were investigated. The optimal reaction condition was finally determined as follows： stainless steel plate and graphite plate were chosen as anode and cathode respectively, the pH value was 4.0, the reaction time was 150 min, the space between polar plates was 3 cm and the current density was 5.0 mA/cm2. Under the above condition, the removal rate of CODcr by the said process reached 57.30%, the said method provided reference for semi-coking wastewater treatment project.
