Gongye shui chuli混凝沉淀在垃圾渗滤液的深度处理工艺中是非常必要的预处理环节。传统的混凝工艺处理垃圾渗滤液普遍存在水资源回收率低、污染物去除率低、絮凝体松散等缺点。基于收缩脱水絮体致密化理论，提出了垃圾渗滤液的延时搅拌造粒工艺，通过长时间高强度的机械搅拌实现悬浮物的均一化。研究结果表明，在pH=12、搅拌强度为1 500 r/min、PAC和PAM投加量分别为3 000 mg/L和60 mg/L的最佳条件下，SS、浊度、COD的去除率分别可达92.33%、99.92%、35.84 ...

凝胶体系中生物分子-金属离子沉淀的LIESEGANG现象研究:胆酸与金属离子形成的周期性沉淀及其影响因素
, 2000 讨论了凝胶介质、胆酸浓度、金属离子种类及其浓度等因素对胆酸与金属离子沉淀的影响及其规律 ,实验结果表明 :沉淀的 L IESEGANG现象与胆酸分子和金属离子之间的作用有密切的关系。三价稀土离子倾向于和胆酸分子形成周期性环状结构沉淀 ;过渡金属离子与胆酸分子形成的沉淀形态外貌则比较复杂 ,有的形成了规则的周期性沉淀环 ;有的则由较大球形颗粒形成 ,排列也不规则 ;还有的在形成环结构时 ,形成了分形图案。多离子体系中 ,离子之间存在强烈的相互作用 ,离子之间既相互影响 ,又相互协作 ...
