硫酸改性粉煤灰做污泥脱水剂研究
Study on the Application of Suffuric Acid Modified Fly Ash in Sludge Dewatering
摘要
Abstract
[ Objective] The aim was to reduce the damage of sludge farm application on soil and crops,and reduce the cost of sludge dewatering. [ Method ] With polyacrylamide (PAM) as a flocculant and fly ash modified by sulfuric acid ( MFS) as a coagulant, two experiments of sludge dewatering were made by dosing PAM separately and by dosing PAM joined with MFS. [Result] PAM dosage decreased from 1% of the weight of 100 ml sludge dried to 0.5% ,by 50% reduced. The moisture content of sludge cake decreased from 83.56% (when 1% PAM dosing separately) to 77.43%. And the volume of sludge cake reduced about 17%. [Conclusion] The test results showed that sludge dewatering effects could be greatly improved after 0. 1 g MFS joined as a coagulant.关键词
