摘要
用微电解法对造纸中段废水二级生化处理后出水进行深度处理研究。结果表明:在pH为3、铁炭比(体积比)为2、H2O2投量为0.5 Qth的最优条件下,中段废水的脱色率可达98%以上,CODCr去除率可达78%,微电解是一种经济有效的深度处理方法。
Micro-electrolysis was used to study the advanced treatmeat bleaching effluent from straw pulp paper making process. Results showed that under the optimal condition the value of pH, Fe/Carbon （v/v） and H202 dosage were 3,2and 0.5 Qth respectively, the color and CODcr removal efficiency were 98 % and 78 % respec- tively. Micro-electrolysis is an economical and effective method.
