Abstract:The experiment by iron ore tailings as the main raw material, add a small amount of fly ash, coal gangue, limestone and biological admixture, the preparation of iron ore tailings bio-ceramic filter material. The effect of the material proportion and sintering temperature and the ball size on the bio-ceramic filter material processing sewage pollutant removal efficiency was investigated. Research shows that the optimal proportion of bio-ceramic is: 86%iron ore tailings, 6% coal gangue, 4% fly ash, 3% limestone,… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
