The invention provides a preparation method and an implementation technology for a
petroleum-contaminated
soil remediation agent
system, and relates to a preparation method and an application method for a
soil remediation agent. The
soil remediation agent
system is composed of
soil conditioning liquid, a
petroleum hydrocarbon degrading bacterium agent, a
solid waste carrier, a biological
polymer bacterial agent and a
nutrient solution. The implementation technology comprises the operation steps that the
soil conditioning liquid is sprayed firstly, then the
petroleum hydrocarbon degrading bacterium agent is sprayed, an
oxygen increasing agent is spread, then the biological
polymer bacterial agent is sprayed,
solid fertilizer carrier particles are spread, and finally the biological
polymer bacterial agent is sprayed again. According to the preparation method and the implementation technology for the petroleum-contaminated soil remediation agent
system, the petroleum-contaminated soil remediation agent system can improve the
dissolution effect of petroleum and soil, promote the growth of petroleum
hydrocarbon microorganisms and inhibit the
reproduction of harmful microorganisms; for 5% or less of the petroleum-contaminated soil, the petroleum degradation rate reaches 39-43.7% under the condition that the temperature is 5-10DEG C; and the petroleum degradation rate reaches 59.8% under the condition that the temperature is 15-20 DEG C, and the petroleum degradation rate reaches more than 87.5% under the condition that the temperature is 25-30DEG C.
