采用铁炭微电解预处理法对中纤板热磨废水进行处理，研究铁炭微电解法预处理对废水中COD、木质 素等去除率的影响。单因素实验研究结果表明，最佳中纤板热磨废水处理工艺条件如下：原水pH为3，铁炭 体积比为1∶1，填料投加量为300 mL/L，反应时间为80 min，混凝pH为85，混凝沉淀时间为120 min。在 此条件下，COD、木质素和SS的去除率分别为74.24 %、89.77 %和91.27 %，且重现性良好。对比实验表明 ，混凝沉淀过程在热磨废水处理中所起的作用要比电化学过程大，是影响中纤板热磨废水处理效果的关键 因素。
Abstract
The ferriccarbon microelectrolysis was employed to pretreat the hot grinding wastewater from medium density fiberboard production. The effect of the pretreatment on the removal rate of COD, lignin and SS of wastewater was studied. According to the results of singlefactor experiments, the optimum technologic conditions were obtained, i.e., influent pH value was 3, V(Fe)∶V(C) ratio was 1∶1, dosage of Fe and C wastewater was 300 mL/L, reaction time was 80 min, coagulation pH value was 8.5 and sedimentation time was 120 min. Under this condition, the removal rate of COD, lignin and SS reached 74.24 %, 89.77 % and 91.27 %, respectively. It was also pointed out by the comparative experiment that the effect of coagulation and sedimentation was more important than that of microelectrolysis. They were the key factors in the whole pretreatment.
