本研究以生活污水处理厂的脱水污泥为对象，实验研究出一种污泥改性脱水剂，使含水率75-85%的污泥，改性后压榨脱水，污泥含水率降到40-50%，且在常温常压下进行，无需消耗热能，也无恶臭产生，滤饼对重金属有很好的稳定作用，即使填埋处置，也不会对地下水造成威胁，改性剂用量少，运行费较低。还可以加入秸秆粉提高热值，满足焚烧要求，使污泥得到彻底处置。

The object of this study is sludge of Sewage treatment plant, this experiment developed a sludge modified dehydrating agent. which makes the sludge with 75-85% moisture content becomes to sludge with 40-50% moisture content after it is compressed, and due to it works at normal temperature and pressure, so no consumption of heat, no stench generated, the slurry filtercake has a good stabilizing effect for heavy metals, so even if landfill disposal but no threat to groundwater. Little modifier used, lowel operating cost. Which Can also improve calorific value by adding straw powder, to meet the burning requirements, so that the sludge treated totally.
