摘要
采用铁炭微电解工艺对亚麻生产废水进行预处理。探讨了填料种类、pH值、反应时间对微电解法去除CODCr的影响。试验结果表明:在铁炭质量比为1,进水pH值为3.0,反应时间为3 h,采用曝气方式,Ca(OH)2投加量为1.5 g/L的条件下,CODCr去除率可达31.8%左右,可生化性由0.21提高到0.47,为后续生化处理创造了有利条件。
Micro-electrolysis process was used to pretreat wastewater from flax production.The influences of filling material,pH value and reaction time on CODCr removal were investigated.The results of the test showed that： when the iron-carbon mass ratio was 1,the influent pH value was 3.0,the reaction time was 3 h,the Ca（OH）2 dosage was 1.5 g/L,using aeration method,the removal rate of CODCr could reach about 31.8%,the biodegradability increased from 0.21 to 0.47,which provided favorable condition for the subsequent biochemical treatment.
