In this paper, the components of edible canna residue and the refining conditions were studied. The refined edible canna residue mixed up corrugating medium was processed to corrugated base paper. The results show that the strength properties of corrugated base paper are optimal when the refining clearance is 2.4mm and the time is 4min. The corrugated base paper strength is best at the edible canna residue dosage 30%.
This paper focused on the effluent chroma which is a long-term puzzle about the aerobic treatment for pulping midcourse wastewater. The organic in the influent and effluent was tested by GC-MS. The analysis indicates that the macromolecular lignin-type substances are partly degraded using aerobic technique. Some micromolecular substances are produced accordingly, which leads to the auxochrome groups and chromophore groups increasing. There are two organic coloration compositions in influent but three in effluent, which account for 22.98% of the organic substances in influent but 33.12% of the organic substances in effluent.
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.
