METHOD FOR ANAEROBIC DEGRADATION ENHANCEMENT OF PETROLEUM COMPOUNDS BY SUPPLING ELECTRON ACCEPTERS

摘要

PURPOSE: A natural purification method of a petroleum-based chemical material with an electron acceptor is provided to increase profitability of purification by contaminating water by supplying a small amount of the electron acceptor with microorganism. CONSTITUTION: A natural purification method of a petroleum-based chemical material includes a step for supplying an electron acceptor after decomposing the petroleum-based chemical material with anaerobe. The petroleum-based chemical material is selected from benzene, toluene, ethylbenzene, xylene and methyl tert-butyl ether. The electron acceptor is nitrate, sulphate or trivalent iron salt.
