METHOD FOR EVALUATING MICROBIAL DEGRADATION CAPACITY IN ORGANIC SUBSTANCE-POLLUTED SOIL, AND METHOD FOR PREDICTING POLLUTED SOIL RESTORATION SPEED

摘要

PROBLEM TO BE SOLVED: To provide a method for evaluating a microbial degradation ability of polluting organic substance under a polluting source environment, and a polluted soil restoration speed on the basis of the microbial degradation ability.;SOLUTION: The method for evaluating a microbial degradation capacity in an organic substance-polluted soil comprises: determining the peak value X_{Q, m} of quinone species total concentration corresponding to an organic substance-degrading microorganism in polluted soil on the basis of the measurement of a quinone profile and then determining the microbial degradation capacity Z_m in a polluted site from the peak value. The method for predicting the polluted soil restoration speed comprises determining a site degradation capacity constant k_s1 on the basis of the microbial degradation capacity Z_m, and then determining a temporal microbial biomass dynamic state and a polluting organic substance-degrading speed from the same on the basis of a certain calculating formula.;COPYRIGHT: (C)2010,JPO&INPIT
