The invention discloses a method for treating
phenol-containing waste water by
sawdust immobilized
alcaligenes faecalis. The method has the advantages that (1) the immobilized
alcaligenes faecalis is easy to culture and has the advantages of simple immobilization process, excellent
catalytic degradation effect, resistance to high-concentration
phenol-containing waste water with the concentration of
phenol up to 3000mg.milligram<-1>, strong phenol
decomposition capability and repeated use; (2) the carrier of the immobilized
alcaligenes faecalis is
sawdust, and modified utilization of the
sawdust is realized by a chemical method, so the method improves the treatment efficiency for the phenol-containing waste water by means of microbial degradation, and has a broad development prospect; (3) the immobilized
alcaligenes faecalis prepared through taking sawdust as the carrier has excellent elasticity, strong resistance to temperature and pH value, stable degradation property and long
half life period; and (4) when used for treating the phenol-containing waste water, the sawdust immobilized
alcaligenes faecalis has the advantages of simple process, low running cost, moderate conditions,
environmental protection, uneasy loss of thalli,
high concentration of
microorganism inside the carrier, quick degradation speed, high degradation efficiency and no secondary
pollution, and can realize continuous industrial degradation of the phenol-containing waste water at the same time.
