results showed that thickened sludge need the least flocculant while digestive sludge need the most flocculant, with all the flocculants having optimum dosages.
结果表明,浓缩污泥所需要的絮凝剂最少,消化污泥所需要的絮凝剂最多,并且各种絮凝剂都存在着最佳投加量。
quite a number of expenses were paid for chemical consumption in thickened sludge de-watering operation in municipal wastewater treatment plant.
城市污水处理厂污泥浓缩脱水的药剂消耗是主要的运行费用。
polymer is normally added to enhance solids capture, overflow is recycled, and thickened sludge withdrawn for further dewatering and disposal.
通常聚合物会被添加来增加固体截留(物质),溢流被再循环,浓缩污泥被抽取以用来进一步脱水和处置。
