| Abstract: | The technical situations of PTA wastewater treatment in China and overseas are described. The influential factors,such as pH ,reaction time and the dosage of oxidizing agent,on the removal rates of ehroma and COD have been investigated systematically. The operation conditions of the wastewater treatment are optimized through experiments. The CODcr of the PTA water has finally been reduced to 420 mg/L with lower cost and convenient operation. Then,the water goes to the biodegradation system,being treated for lowering its COD to less than 150 mg/L. This method has some merits,including convenient operation,reasonable technical process ,ideal treatment effect,operable conditions and friendly environment. |
