Embodiment Construction
[0078] The present invention takes the microcosm experiment as an example to actually verify and apply the invented new energy metabolism index STCA. Using methods such as correlation analysis, analyze the correlation difference between STCA index and other energy metabolism indexes and electron donor index COD, electron acceptor index DO and other material conversion indexes, and find the most suitable energy metabolism index for characterizing the microbial degradation process of BTEX; and Using the regression analysis method, the data related to the energy metabolism index and the material transformation index are fitted, and the regression curve is established to provide theoretical support and technical methods for the application of the energy metabolism index in the field.
[0079] The microcosm experiment used a 500ml infusion bottle as the carrier, and the experiment was divided into 5 groups, namely the benzene series-chlorinated hydrocarbon pollution group, the benze...

The invention relates to the field of degradation of petroleum pollution microorganisms in underground water, in particular to a construction method of an energy metabolism index related to substanceconversion in the degradation process of the petroleum pollution microorganisms in the underground water. The degradation of underground water pollution microorganisms takes organic matters as electron acceptors and inorganic matters as electron donors, and the microorganisms for generating ATP by utilizing an oxidative phosphorylation way are called chemical heterotrophic microorganisms. Researches show that most of underground water microorganisms are chemical heterotrophic microorganisms, therefore, the oxidative phosphorylation path is closely related to substance conversion of organic matters. According to the invention, based on the basic principles of substance conversion and energy metabolism in the degradation process of underground water petroleum microorganisms, a substance-energy coupling relation model is constructed, and a new energy metabolism index is formed.
Description
[0001] technology [0002] The invention relates to the field of microbial degradation of groundwater petroleum pollution, in particular to a [0003] A method for constructing energy metabolism indicators related to material transformation in the degradation process of polluting microorganisms. Background technique [0004] Petroleum pollution has a wide range, great harm, and long cycle. Microbial degradation is the key to the natural attenuation of petroleum pollutants. It is difficult to comprehensively monitor and evaluate microbial degradation by existing substance concentrations, microorganisms, and even monomer isotope analysis. Energy is a state variable throughout microbial degradation. It is intertwined with material transformation during the microbial degradation of petroleum pollutants, which can explain microbial degradation from a new perspective. However, there is currently a lack of energy metabolism indicators related to material conversion. [0005] Most of...
