Chemical Embedding Immobilization Technique of Micrococcus sp. Used in Contaminated Surface Water Remediation
According to the characteristics of contaminated surface water, a stain of Micrococcus sp. (Micrococcus sp. N3-9P) that could remove CODCr efficiently was picked out from the slowly flowing oil-polluted riverbed sludge in Liaohe Oil Field, and then it was immobilized by chemical embedding technology. Through the conditional tests of immobilizing parameters, an improved co-immobilization technique with PVA and sodium alginate was determined, and the immobilizing gel was made of 10.5%PVA, 0.5%Na-Alg 3% activated carbon and traces of auxin. Experimental results showed that the Micrococcus sp. Immobilized in such a way has the ability to remove 70.9% CODCr in contaminated surface water after 96 hours, I.e., 33.6% higher than the removal rate by free thalli.
