Through concrete and chemical oxidation are two methods of a group of textile wastewater textile processing, the impact of aggregate conditions for pH, the Pac voted to increase the volume and response time, resulting in the best conditions for pH=12,PAC to aggregate volume of 12mL/200mL; impact oxidation conditions for H2O2 vote plus volume, FeSO4 • 7H2O vote plus volume, pH and response time, resulting in the best conditions for H2O2 oxide vote plus volume increases in the volume 300mg/200mL,pH 4ml/200mL,FeSO4 • 7H2O vote for the value of 4 hours 60 minutes. Experimental results show that a single aggregate and can enable printing of a single chemical oxidation removal and wastewater CODCr Detreated rate of the national "textile dyeing industry water pollutant discharge standards" (GB4287-92) level emissions standards.

Oxidize two methods through the coagulation and chemistry to carry on processing separately to some textile group printing waste water, affects the coagulation the condition is pH, PAC throws the increment and the reaction time, obtains the best coagulation condition is pH=12, PAC joins the quantity is 12mL/200mL; The influence oxidation condition is H2O2 throws the increment, FeSO4 □7H2O throws the increment, pH and the reaction time, obtains the best oxidized condition is H2O2 throws increment 4ml/200mL, FeSO4 □7H2O throws increment 300mg/200mL, the pH value is 4, the time is 60 minutes. The experimental result indicated that, the sole coagulation and the sole chemistry oxidation all may cause the printing waste water CODCr removing rate and the decolorization rate achieved the country "Spinning and weaving Dyes the Entire Industry Water pollution Discharges Standard" (GB4287-92) a level to discharge the standard
