摘要
城市污水处理厂在处理污水过程中产生大量的污泥．由于污泥的含水率很高．如不处理将占用太大的空间，而且污泥的运输成本会大大提高。因此．污水厂的污泥脱水处理至关重要。通常。这些有机质污泥均是由亲水性带负电荷的胶体颗粒组成，颗粒大小很不均匀而且很细小，可缩性大，过滤比阻抗值也大，因而过滤脱水性能较差。污泥机械脱水前需加入污泥脱水剂对其进行调理．以改善其过滤脱水性能，降低水处理成本，提高净水效果。因此，在城镇饮用水、工业用水、工业废水和城市污水净化处理中使用污泥脱水剂成为一种趋势．
Study on application of dehydration of trial product of highly efficient dehydrant,abbreviated to CPAM,for treatment of sludge dehydration and flocculent treatment of effluent from papermaking and dyeing and printing has been carried out.The results show that CPAM could be well solubilized and it also has high efficiency in sludge dehydration.Moreover,it has significant effect on the removal of COD and chroma from effluent produced from papermaking and dyeing and printing with its complex combined with inorganic flocculent.
