The maximization research on formaldehyde waste gas purification performancein Compound biological reactor

摘要

In this article, the formaldehyde waste gas purification performance in the compound biological reactor had been studied. The influence to the formaldehyde purification performance had been inspected by changing the import gas density and the gas flow amount in experiment. Under being suitable operating condition, the result indicated the biggest purification performance when pH value was 6-8, the gas flow amount was 400 L/h, the circulation liquid flow quantity was l0L/hthe formaldehyde import gas density is about 300mg/m3, the biggest biochemistry elimination quantity might achieve 13.70 mg/Lh.
