Open publisher page 0 citations

Abstract

The micro-electrolysis method has characteristics including the functions of oxidation-reduction, flocculation,electro-enrichment, filtration-adsorption and so on. The decoloring treatment of alkali straw pulp bleaching effluent and the influence factors are studied in this paper. The results show that when stiring, the ratio of iron to carbon is 1:2 , pH value is 2, the amount of Fe is 800mg·l-1, reaction time is 30 minutes,the removal rate of chromaticity is up to 95% and the treated effluent is almost transparent.
