查询词典 floc

Its rule of change was obtained. On the basis of other studies, the flocculation kinetics and flocs structure was studied. By making some assumptions, collision frequency were presented. Then the the flocculation kinetics model was established through population balance equation. Comparison of experimental data and modeling results indicate that there are the same trend between the two. So the model can predict flocs number and size during flocculation of Yellow River's loess particles without using empirical parameters. The TEM and SEM were used to obsever flocs in the study of floc structure. The flocculation was divided as flocculi, floc and floc aggregate. The flocs structure model was established by assumption that particles position in floc accords with tetrahedron. The fractal dimension of model and experimental flocs was found to be coincident. So the model can reflect the structure of flocs formed in flocculation of Yellow River's loess particles by macromolecule flocculant at a certain extent.

最后，本文还对絮凝动力学和絮体结构进行了研究，在前人研究的基础上，针对高分子絮凝黄河泥沙，对絮凝过程作了一些符合试验条件的假设，建立了颗粒碰撞频率表达式，应用了颗粒数量平衡方程，从而建立了絮凝过程的动力学生长模型，模型计算结果与试验数据对比表明，二者趋势一致，在没有使用经验参数的情况下基本上能够描述黄河泥沙絮凝过程中絮体数量和尺寸分布的变化过程；对絮体结构的研究中，应用扫描电子显微镜和透射电子显微镜对絮体进行了观察，将絮体分为絮粒、絮团和絮网三个不同的生长阶段，通过假设颗粒结合位置符合正四面体，建立了絮体结构模型，计算得到的模型絮体分形维数基本与试验中的实际絮体相符，在一定程度上能眵反映高分子絮凝黄河泥沙生成的絮体结构。

Brownian movement and the hydraulic condition required is only that the coagulant can be dispersed in the water rapidly;As the floc is growing further,the condition of making the floc diameters controlled in a certain limit is to be provided as well as the condition favorable for the collision of the floc.

得到细小粒子的凝集动力由布朗运动决定，此阶段只需要有将混凝剂迅速分散于水中的水力条件；在絮体进一步成长过程中除造成有利于絮体碰撞的水力条件外，还要造成絮体粒径控制在某一限度之内的水力条件，这样可以得到密度高、沉淀效果好的絮体。

At the same time, mass production of wooden lattice door mats and cushions, floc coconut, palm floc, sisal floc, water straw, paper rope, such as hand knitting material and packet edge sisal, straw carpets, car mats foot indoor carpet, cups mats, paper cloth, sisal wallpaper single fiber mesh such as woven fabrics, as well as for the export of all types of small packing rope type, line type of environmentally friendly products.

同时亦大量生产门口垫及木格座垫，椰絮，棕榈絮，剑麻絮，水草绳，纸绳等手工编结物和包边剑麻，草绳地毯，轿车室内垫脚毯，杯垫，纸布，剑麻单纤维墙纸网布等机织物以及各类专供出口的小包装绳类、线类环保产品。

The main products are: water straw, sword hemp rope, yellow hemp rope, rattan chairs, ginger leaf rope, rope banana, coconut rope floc, palm rope, rope leaves, bamboo chairs,, Paper Rope, multi-layer package Rui rope, sisal rope Bagu polishing, and coconut rope pattern screwdriver floc more than 10 categories, such as dozens of kinds of specifications products.

主要产品有：水草绳、剑麻绳、黄麻绳、藤绳、姜叶绳、香蕉皮绳、椰絮绳、棕榈绳、树叶绳、竹绳、布绳、纸绳、多层包蕊绳、剑麻八股抛光绳、椰絮缧纹绳等十多个品类几十种规格产品。

The results also revealed a tendency of decrease in the fractal dimension with the increase of floc size, which is resulted from the unproportionate growth between the floc size and the number of the primary particles contained in the flocs.

同时计算结果表明，絮凝体的分形维数有随其粒径增大而逐渐降低的趋势，其原因是絮凝体的成长粒径与絮凝体中所包含的初始颗粒增长速度不成比例。

This paper analyzed it with the use of two-phase flow simulation of CFD in a WWTP in Beijing. The variation of concentration velocity field in different conditions is studied with dividing the floccules into macro-floc and micro-floc.

研究结果表明，二沉池出水中的颗粒主要为小絮体，SS超标主要是因为污泥中小絮体比例过大，降低污泥中的小絮体比例便可以降低出水SS，但因氧化沟工艺的污泥龄一般较长，所以污泥老化现象严重，小絮体的比例一般较高。

The resulting microbial floc is settled in a sedimentation vessel called a clarifier or thickener.

生成的微生物絮凝物就沉淀在一个被称为沉淀池或压滤池的沉淀器中。

Results show that adding microparticulate silica could further increase the floc size.

结果表明，添加微粒硅可能进一步增加絮块大小。

So the functions of the activated sludge floc is changed, some new functions was come up.

MCMP菌剂对污水污泥减量影响是污水微生态系统的结构改变与功能的统一。

After that, in the role of wind, these crystals in the air collision with each other, and eventually formed a floc snow.

随后，在风的作用之下，这些晶体在空中互相碰撞，并最终形成了絮状的雪花。

The role of the environment is very important.

的作用，环境是非常重要的。

At that time, the High Court of England and Wales Court of Queen's Bench president of William Murray, Lord Mansfield in June 22, 1772 ruling:"No matter then there is the inconvenience, but there must be a decision, I can not say that this case under the law in England are permitted or authorized; are so black should be released."

当时的英格兰及威尔士高等法院王座法庭院长William Murray， Lord Mansfield于1772年6月22日宣判：「无论有那麽不便，但总要有个决定，我不能说这件案在英格兰法律之下是准许或认可；所以黑人是应该被释放。
