Abstract

The treatment of the waste water containing Linear Alkyl benzene sulphonate (LAS) was studied by the Sequencing Batch Reacto r(SBR)activated sludge process. The activated sludge was domesticated to get the micro biome which had a prominent degradation effect on the LAS. Simulated the SBR and find the effects of aeration rate, sedimentation time, pH, metal ion on the LAS degradation of the activated sludge, and got a preliminary study of organic matter degradation kinetic in SBR. It shows that the LAS concentration levels reached 12 g·mL-1 in the SBR reactor, the best aeration rate is 0.2m3·h-1, the best sedimentation time is 12 h and pH value is 7, the removal rate of LAS reach 81%. K+,Fe2+,Mg2+ and Ca2+ can restrain the LAS degradation of the activated sludge in different degrees, but Mg2+,Ca2+ can slightly restrain the LAS degradation of the activated sludge, the removal rate of LAS reach 87%. The activated sludge's organic matter degradation kinetic is v=1.01×10-4XS/ (1.011+S).
