摘　　要：为了解决松香废水对环境的污染问题,采用内电解—生物法—混凝沉淀法处理松香废水。结果表明,在内电解反应时间为10 h、生物法停留时间为24 h、混凝沉淀法选用混凝剂为聚合硫酸铁、最佳投药量为200 mg/L时,出水COD<70 mg/L,达到污水综合排放标准的一级排放标准。废水经过内电解处理后可生化性明显提高,对其机理进行研究发现,除特别难处理的高分子物质外,其他物质均能得到很好的处理。The treatment of colophony wastewater by inner electrolysis - biological process - coagulation process has been studied in this paper. The results show that the final effluent CODcr can be controlled under 70 mg/L when the inner electrolysis reacting time is 10 hours and the biological process HRT is 24 hours and the coagulating agent is aggregate iron - sulfate and the dosage is 200 mg/L. The inner electrolysis can increase the biodegradability of colophony wastewater. The study on its mechanism found that： other substances can be well disposed except the special refractory of the polymer materials.
