摘　　要：利用动态微电解／SBR法处理制漆废水（COD为2110～2660mg／L），考察了pH值、铁碳比、反应时间、装置转速对去除废水中COD的影响，同时还研究了动态微电解法对废水pH值的调节作用。结果表明，高铁碳比、酸性条件、延长反应时间、高转速有助于对COD的去除，微电解装置对原水的pH值存在中和调节作用；在pH值为4．6、铁碳比为2：1、反应时间为60min、反应装置转速为4r／min的条件下串接SBR工艺后，出水COD为80mg／L、BOD，为14mg／L，且动态微电解装置在10d的连续运行过程中没有发现钝化现象，这是因为铁屑之间的摩擦有助于减轻钝化．Dynamic iron filings micro-electrolysis/SBR process was used to treat lacquer-making wastewater with COD of 2 110 to 2 660 mg/L. The influence of pH, Fe/C ratio, reaction time and rota- tion rate on COD removal was investigated, and the neutralization of micro-electrolysis on wastewater pH was studied. The experimental result indicates that the high Fe/C ratio, acid condition, long reaction time and high rotation rate can enhance the COD removal. The micro-electrolysis can neutralize the influent pH. The final effluent COD and BOD5 from SBR are 80 mg/L and 14 mg/L under the conditions of pH 4.6, Fe/C ratio 2 ： 1, reaction time 60 minutes and rotation rate 4 r/rain. The dynamic micro-electrolysis device does not show passivation after ten days of continual running, which is attributed to the friction between iron filings.
