Abstract

The invention provides a carbon fiber ecological grass production process, comprising the following steps: uncoiling the carbon fiber tow reel through the first godet roller and then through the expansion groove so that the diameter of the original carbon fiber filament is 1.1-1.5 times that of the expanded one. Cross-linking is performed on the second godet roller, and then the carbon fiber filaments are cut into 20-100 cm sections and further dried and cured in an environment with a room temperature below 45°C, and finally 4000-5000 carbon fiber filaments are made into a bundle of carbon fiber ecology Grass, carbon fiber grass prepared by this process has good dispersibility in water, high biofilm adhesion rate on its surface, strong water treatment ability, and is not easy to break, and can be recycled.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a production process of carbon fiber ecological grass. Background technique [0002] Water is an important resource for people's survival and social development. Due to the development of social economy and the increase of human activities, a large number of industrial sewage and domestic sewage have been produced, and the problem of water environment pollution has become increasingly prominent. [0003] In recent years, many researchers have conducted in-depth research on the treatment technology of sewage contaminated surface water, and achieved good results. Commonly used technical solutions are mostly water aeration, microbial inoculum delivery, aquatic plant cultivation, biofilm method and even water filtration. The above-mentioned technologies all have different degrees of defects in the improvement of water quality. [0004] Carbon fiber grass has a high degree o...
