Culture medium insert piece

Abstract

The invention relates to the field of microbial strain extracting devices, in particular to a culture medium insert piece arranged in sewage to be treated for extracting strains. The insert piece is provided with a framework arranged in the sewage to be treated, wherein the upper end of the framework is connected with a floating part; the inner side of the framework is provided with a carrier foradsorbing a culture medium; the framework is square, and the periphery of the framework consists of stainless steel and / or plastic steel; two side faces with larger surface areas of the framework areprovided with stainless steel net pieces and / or polyvinyl plastic net pieces; the floating part is a PVC plastic pipe both ends of which are sealed; the carrier is made of melamine foam with holes; and the culture medium consists of at least one anaerobic culture medium and at least three aerobic culture media. The invention has the advantages that the insert piece is suitable for the bio-treatment of various polluted water and industrial sewage, and the action of purifying the water is achieved through the culture of the extracted microbial strains.

Description

technical field [0001] The invention relates to the field of microbial strain extraction devices, in particular to a culture medium insert placed in sewage to be treated to extract strains. Background technique [0002] The core of sewage biological treatment technology is biology. Any pure microbial strain produced in a high-clean environment is difficult to adapt to the complex natural ecological environment of various polluted water bodies. How to enrich and extract in the sewage to be treated is targeted, The application of microbial strains with strong purpose and effect is the photo-alkaline problem to be solved in the biological treatment of sewage in the environmental protection community. The immobilized microorganism technology is widely used in the field of water treatment. In the immobilized microorganism technology, the water treatment performance of the strain itself has a great influence on the final sewage treatment effect. However, the strains screened by th...

Problems solved by technology

Immobilized microorganism technology is widely used in the field of water treatment. In the immobilized microorganism technology, the water treatment performance of the strain itself has a great influence on the final sewage treatment effect, but the strains screened by the current strain screening method only account for a small amount of bacteria. part, so the effect on sewage treatment is not obvious
