Experimental Study on Quinacridinone Pigment-intermediate Wastewater Treatment by SBR Biological behind Treatment

Fei Ma

Abstract

This paper studied the research work for SBR used to treat Quinacridinone pigment-intermediate wastewater,and the influence on treatment effect by changing aeration time,pH,the COD of input wastewater.The Results showed that under the experimental condition of pH 7.0～8.5,aeration time 6h,the COD of input wastewater 1 000～2 000mg/L,the removal rate of COD can reach 71.3%～77.2%.
