摘要
利用铁炭在水中发生的内电解过程可以有效地去除染料生产废水的色度 ,并提高污水的可生化性 ,同时对CODcr也有一定的去除效果。试验结果表明 ,进水CODcr为1200mg/L的染料废水 ,经内电解法处理后 ,脱色率可达75 %以上 ,CODcr去除率也可达到45 %左右 ,该法对CODcr的处理效果比单纯的石灰乳中和混凝沉淀法要高10
The iron-carbon internal electrolysis in water may effectively eliminate the color of the waste water from dye-stuff production, improve the result of the biochemical treatment of the waste water and has a certain effect on the removal of CODcr. Testing results show that after the treatment by internal electrolysis, the decolourization rate of the inlet dye-stuff waste water with 1 200 mg/L of CODcr may reach 75% or even higher while the removal rate of CODcr may reach about 45%. The result of the treatment of CODcr by this process is more than 10% better than that by only using the process of lime milk neutralization, coagulation and sedimentation.
