摘要
使用铁铝碳为基础材料制成新型微电解材料,以聚乙烯醇(PVA)模拟废水为研究对象,筛选出最佳处理工艺参数为:在曝气条件下,反应时间60 min、进水pH为5、材料一次投加量465 g/L。通过处理实际退浆废水,比较了此新型微电解材料与市售产品的性能,新型微电解材料出水的CODCr和PVA去除率分别为48.7%和36.7%,BOD5/CODCr为0.32;而市售材料出水的CODCr和PVA去除率仅为15.3%和11.7%,BOD5/CODCr为0.19。采用混凝和微电解技术预处理实际退浆废水,再联合活性污泥法处理后,最终出水CODCr去除率为85.4%,PVA去除率为66.2%.
A new type of micro-electrolytic material based on iron,aluminum and carbon was employed in this research.Taking polyving akohol simulated wastewater as the research subject,optimum processing parameters were discovered as follows:under the condition of aeration,the reaction time was 60 min,the wastewater pH value was 5,and the material dosage was 465 g/L. Compared with commercially available products,the removal rates of CODCr and PVA by the novel microelectrolytic material were 48.7% and 36.7%,respectively,and the BOD5/CODCr ratio was 0.32,while the effluent removal rates of CODCr and PVA by the commercially available micro-electrolytic material were only 15.3% and 11.7%,respectively,and the BOD5/CODCr ratio was only 0.19. Coagulation and micro-electrolysis were employed as pretreatment methods for desizing wastewater. Combined with the activated sludge process,the effluent removal rates of CODCr and PVA were 85.4% and 66.2%,respectively.
