mycobacterium gilvum CP 13 was deposited in China General Microbiological Culture Collection Center (CGMCC) on Jul. 22, 2013 with a CGMCC number of CGMCC No. 7963; and (2) applying a calcium alginate and chitosan to encapsulate the bacterial broth in a microcapsule through layer-by-layer self-assembly to produce a microcapsule material capable of reducing pollution containing polycyclic aromatic hydrocarbons. The present invention produces a microcapsule material with the microorganic activity through layer-by-layer self-assembly, which has superior adaptability to the environment and good ability to reduce pollution containing polycyclic aromatic hydrocarbons. The microcapsule material of the present invention can be used in bioremediation of industrial wastewater containing polycyclic aromatic hydrocarbons and contaminated soil containing polycyclic aromatic hydrocarbons.

Abrégé

The present invention relates to the technical field of polluted soil restoration. Disclosed are a mixed eluant for synchronously removing polychlorinated biphenyl and heavy metals in soil, and the preparation and a use thereof. The mixed eluant is prepared by dissolving active components comprising saponin and Tween 80 in water. The mixed eluant can be used for restoring soil compositely-polluted by polychlorinated biphenyl and heavy metals. The use of the mixed eluant comprises the steps of: taking soil compositely-polluted by polychlorinated biphenyl and heavy metals, and performing elution by adding the mixed eluant of the present invention, so as to implement restoration of the soil compositely-polluted by polychlorinated biphenyl and heavy metals. The mixed eluant of the present invention has wide raw material sources, has a low price, is environmentally-friendly, has a good elution effect and a high elution rate, and has an elution rate of higher than 80% for pollutants in the compositely-polluted soil.
