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. |
