| 摘 要： | 壳聚糖絮凝剂对污泥脱水性能有显著的影响且无毒害,通常可作为污水处理厂污泥脱水的添加剂.本文以某市污水处理厂剩余污泥为对象,研究了壳聚糖絮凝剂对污泥脱水性能的影响.初步实验表明,在l00mL剩余污泥中投加浓度为6g/L的壳聚糖溶液6mL时可达到污泥的最小含水率,为70.42%;污泥中有机质含量、含水率、SV30随絮凝剂投...

| Abstract: | Chitosan flocculant sludge has significant effect on dewatering properties and can be used as a non-toxic.It is usually used sewage as dewatering additives.Based on sludge sewage treatment plant,this paper studies chitosan flocculant sludge dewatering properties.Preliminary experimental results show that addition of 100 mL 6g/L for 6mL chitosan solution in the sludge concentration of malign can be achieved when the minimum moisture content,as the sludge 70.42%.Sludge organic matter content,moisture content,... |
