    Various waste water from dye-stuffy could badly pollute environment with their high toxicity and p(CODCr). The iron-carbon internal electrolysis in waste water may effectively eliminate the color of the waste water from dyed-stuff production, improve the result of the subsequent biochemical treatment of the waste water and has a certain effect on the removal of p(CODcr). Testing results show that treatment effect is influenced by filling constitutes, pH, settle time and coagulation aeration. After the treatment by internal electrolysis, the removal rate of the inlet dye-stuff waste water from 2 000 mg/L p(CODcr) and degree color 2 048 may reach 56% and 75% to 860 mg/L and 256. The result of the treatment of p(CODcr) by this process is more than 22. 5%, better than that by only using the process of lime milk neutralization coagulation and sedimentation. , and biodegradability has been improved from 16% up to 34%.
