摘要
Abstract
In this paper the urban sewage treatment plant excess sludge derived bio-char is used to adsorb Cd2+ , which benefits to the sludge disposal of urban sewage treatment plant. It provides a new way for treatment and disposal of heavy metals in sewage as well as carbon emission reduction. The result shows that the optimal activate temperatures for the sludge from different sewage treatment plants are different and that of the First Kunming Sewage Treatment Plant, the Third Kunming Sewage Treatment Plant and the Fifth Kunming Sewage Treatment Plant are 300℃, 400℃ and 400℃ respectively; the Cd2+ aclsorbability increases with the pH; the result of adsorption model fitting shows that Freundlich model has a better relevance than Langmuir model.关键词
