| 摘 要： | 化学调理是目前生活剩余污泥预处理的主要方法,而调理剂的选用直接影响到污泥脱水的效果.本章利用不同种类调理剂的优势,通过各种调理剂正交复配组合对生活剩余污泥进行强化混凝脱水试验,发现无机-有机复配调理剂(I-O)脱水效果最佳.同时,使用单一无机调理剂(PC和PS)、单一有机调理剂(PM)和无机-有机复配调理剂(I-O)对...

| Abstract: | Chemical conditioning is main method of pretreatment for domestic excess sludge.Choice of conditioner directly affects the effect of dewatering,which determines the quality of following treatment.Due to advantages of different chemical conditioning agents,complex conditioning agent got by orthogonal compound experiment was used for treating excess sludge to dewater.It was found inorganic-organic complex conditioning agent(I-O) has the best dewatering effect.Indoor experiment was done using single inorganic ... |
