Reactor for surfactant enhanced microbial remediation of contaminated soil

Abstract

The invention relates to soil remediation technology and discloses a reactor for surfactant-enhanced microbial remediation of contaminated soil. The reactor comprises a movable base, wherein a mixing box is fixedly connected to a top of the base, spraying components are arranged on both sides of the mixing box, and a soil turning component is arranged within an internal cavity of the base. Surfactants, microbial agents, and nutrient solutions are mixed in the mixing box and uniformly sprayed onto the soil surface through the spraying components. The soil turning component turns deeply contaminated soil to the surface and promotes full contact between remediation agents and soil particles. Through the integrated arrangement of mixing, spraying, and soil turning on a single movable platform, continuous collaborative operation is achieved, improving pollutant desorption efficiency and bioavailability, enhancing synergistic remediation effects, and significantly shortening treatment intervals.
