Experimental study of saliferous organic wastewater treatment by SBR process

Xianfeng Xu

Abstract

The biofaces of activated sludge,sludge setting performance,COD removal rate and turbidity of effluent under the influence of the sludge organic load and salt content are studied in the SBR process.The results show that the COD romval rate is 86% under organic load rate of 0.15kgCOD(Cr)/kgMLSS·d and salinity of 25g/L,but sludge bulking can be induced by high organic load and high salinity easily in the saliferous organic wastewater treatment by SBR process.
