摘要
采用污泥重力浓缩脱水的方法研究了褐煤热解半焦对污泥调质与深度浓缩脱水的影响。通过污泥调质前后的粒度分析和半焦的扫描电镜图像分析,探讨了半焦对污泥调质与深度浓缩脱水的机理,主要表现在半焦对污泥的吸附作用及半焦对污泥亲水性能的消弱作用。
The lignite semi-coke′s effect on modifying and deep concentrated dewatering of sludge was studied by the method of gravity concentrated dewatering. Explored the mechanism of semi-coke on the modifying and deep concentrated dewatering of sludge. The mechanism mainly manifested in semi-coke′s adsorption on sludge and weakening hydrophilic properties of sludge.
