Abstract
A stacked circulatable microbial electrochemical reactor and a degradation method of petroleum hydrocarbon contaminated soil are provided, which belong to the field of microbial electrochemical soil remediation. The stacked circulatable microbial electrochemical reactor of the present disclosure expands influence range of anodes by a stacked microbial electrochemical system, accelerates the movement of the petroleum hydrocarbon molecules in the contaminated soil by a water circulation system, and improves the mass transfer capacity of soil, thereby increasing the degradation efficiency of petroleum hydrocarbon in the contaminated soil with microbial electrochemical technology from different aspects. The degradation method of petroleum hydrocarbon contaminated soil is provided. The degradation method of the present disclosure is simple in operation and has a high degradation efficiency of petroleum hydrocarbon in contaminated soil.
