Abstract

The present invention provides one kind of soil repairing solid compound microbe microball and its preparation process. The soil repairing solid compound microbe microball is prepared with calcium alginate as embedding material and solid calcium carbonate as solid pore-creating agent to embed petroleum hydrocarbon degrading fungi, bacteria and nutritive matter, and the preparation process includes suspension preparation, microball formation, eliminating pore-creating agent and other steps. The present invention has the advantages of solid carrier maintained, has super large pores for reinforced mass transfer and embedded fungi, bacteria and nutritive matter, and thus possesses the advantages of high mass transferring speed, protection, nourishing, high activity and stability, etc. This kind of solid compound microbe microball may find its wide application in the biological repair of petroleum polluted soil.

Description

technical field

[0001] The invention relates to a solid composite microbial microsphere for soil restoration and a preparation method thereof, which belongs to the preparation technology of microbial preparations for bioremediation of petroleum-contaminated soil. Background technique

[0002] Environmental bioremediation technology is mainly composed of three aspects: (1) The technology of utilizing the metabolic ability of indigenous microorganisms (Natural Attenuation); (2) The method of activating the decomposition ability of indigenous microorganisms (Biostimulation, referred to as biological activation method): (3) Adding A method of specific microorganisms (groups) with the ability to decompose refractory compounds at a high speed (Bioaugmentation, referred to as biological addition method). For the bioremediation process of petroleum-contaminated soil, due to the complex composition, biodegradability and low bioavailability of petroleum pollutants, it is difficult for...
