自由沉淀

沉淀时间的缩短使自由沉淀空间增加，从而影响了污泥颗粒化进程。

Decreasing settling time just leaded to increasing free settling space .

自由沉淀实验数据计算机辅助处理

Computer - aided data processing in the free settling experiment

污泥颗粒化的直接影响因素不是沉淀时间而是自由沉淀空间。

Instead of settling time , free settling space was the direct influencing factor for granulation .

沉淀法是污水处理应用最广泛的方法之一，通过此实验掌握自由沉淀规律。

Sedimentation is applied widely in wastewater treatment . Grasp the regulation of free sedimentation by this experiment .

最后，对混凝实验、自由沉淀实验、絮凝沉淀实验、成层沉淀实验、压缩沉淀实验、滤料筛分实验、过滤及反冲洗实验进行了模拟开发。

Lastly , this thesis paper develops MATLAB GUI of coagulation and flocculation experiment , four experiments of sedimentation , filter material sieve , filter experiment and backwash experiment .

采用丙烯腈（AN）与衣康酸（IA）为共聚单体，以偶氮二异丁腈为引发剂在混合介质二甲基亚砜水（DMSOH2O）中自由基沉淀共聚合，合成了高分子量的聚丙烯腈。

High molecular weight polyacrylonitrile ( PAN ) was obtained by the free-radical suspension copolymerization of itaconic acid ( IA ) and acrylonitrile ( AN ) which was carried out in DMSO / H 2O using azodiisobutyronitrile ( AIBN ) as initiator .
