摘　　要：对杨木BCTMP浆制浆废水进行微电解处理,探讨了微电解处理工艺对废水的影响。实验结果表明,微电解处理时的废水pH值对废水处理效果影响最大,其次是微电解处理时的Fe/C质量比、反应时间和水铁比。在pH=3～4,Fe/C质量比为0.5:l,反应时间15min,铁液比为0.1～0.125的条件下,废水色度去除率>90%,COD去除率>70%,可生化性(BOD/COD)由原来的0.3上升到0.35。采用微电解法处理杨木BCTMP废水,不仅能有效地去除废水的色度及降低COD,而且可以提高废水的可生化性。The effluent from BCTMP of polar was treated with micro-electrolysis method, and the factors affecting the treating effect were discussed. The results showed that pH value was the most important factor to influence the reaction of micro-electrolysis, other factors, such as Fe/C ratio, reaction time and the ratio of Fe/wastewater also had some effect on treatingt efficiency. The optimum conditions of pH value3-4, Fe/C ratio 0.5：1, reaction time 15min and ratio of Fe/wastewater 0.1-0.125, the decolorizing rate is more than 90%, and the CODcr removal rate is above 70%, BOD5/ COD of wastewater increased from 0.3 to 0.35. The experiments also showed that micro-electrolysis method can be used not only to eliminate the color of the wastewater and reduce the COD effectively, but also to improve the biodegradability of the wastewater.
