Cotton fiber membrane, application of cotton fiber membrane and luminescent microbial culture membrane

Abstract

The invention relates to a cotton fiber membrane. The cotton fiber membrane is prepared by sequentially overlapping and pressing two or greater than two cotton fiber layers, wherein two adjacent cotton fiber layers are connected by using connecting cotton fibers; the cotton fiber layers comprise cotton fibers in a first direction and cotton fibers in a second direction distributed in a mutually staggered manner; the density of the cotton fiber layers positioned at the top and the bottom in the cotton fiber membrane is 1.5-2.5 times of the density of the cotton fiber layers positioned on the intermediate layer of the cotton fiber membrane; the pore size of the cotton fiber layers positioned at the top and the bottom in the cotton fiber membrane is 1 / 2 to 1 / 3 of the pore size of the cotton fiber layers positioned on the intermediate layer of the cotton fiber membrane. Compared with other cotton fibers, the cotton fiber membrane disclosed by the invention has adsorption capability and canserve as a microbial attachment supporter. The invention further relates to application of the cotton fiber membrane serving as the microbial attachment supporter. The invention further relates to aluminescent microbial culture membrane, so that the technical effects that in the prior art, the treatment time is long, the cost is high and the effect is not obvious are solved.

Description

technical field [0001] The invention relates to the technical field of fiber membranes, in particular to a cotton fiber membrane, the application of the cotton fiber membrane as a microorganism attachment carrier, and a luminescent microorganism cultivation membrane. Background technique [0002] The prevention and treatment of water eutrophication is the most complicated and difficult problem in water pollution treatment. At present, for the control of eutrophic water pollution, most of them use physical methods such as dredging, aeration, and water injection to dilute; chemical methods including flocculants, chemical agents, etc., and biological methods such as adding microorganisms are used. However, the physical method involves high project implementation intensity, huge equipment transfer costs, and high treatment costs. Both the chemical method and the microbial method may have an impact on the raw water ecosystem environment, and there are problems such as long treatm...
