| 摘 要： | 介绍了一种污水污泥有机调质浓缩和无机调质脱水工艺，它可有效提高污泥浓缩和脱水效率。含水率99％以上的剩余污泥经过有机调质后可快速浓缩至含水率93％左右，去除污泥中的间隙水和表面吸附水。浓缩污泥经过无机调质后可板框压滤脱水至含水率60％左右，脱除污泥中的毛细结合水和部分细胞水，而且实现了污泥重金属的稳定化。

| Abstract: | A wastewater sludge organic conditioning concentration and inorganic conditioning dewatering technology is introduced,which can increase the efficiency of concentration and dewatering of sludge.After the organic conditioning,the surpluse sludge can be concentrated quickly,and the moisture content will fall down from 99.3% to 93%,it removals the gap water and surface adsorption water.After the inorganic conditioning,the concentrated-sludge can be filter-express dewatered,and the moisture content is down to a... |
