Flocculation characteristics of bioflocculant produced by Azotobacter J 25 in glutamic acid wastewater were studied.

考察了微生物絮凝剂产生菌AzotobacterJ 2 5在味精废水中发酵产生絮凝剂的絮凝特性。

The result showed that the concentration of flocculant, pH and temperature of broth played important roles in flocculation.

结果表明，发酵液的pH、絮凝剂浓度和絮凝温度对絮凝效果的影响较大。

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

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。

Performance evaluation for inorganic and organic flocculant's coagulation efficiency in seawater system was made by using high-density clarifier.

文章利用高密度澄清池对无机絮凝剂和有机絮凝剂在海水体系中的絮凝效能进行了综合评价。

The results show that the polymerization and the electrokinetic characteristics of ...

PASiC的电中和能力较PAC有所下降，且Al/Si摩尔比越小，PASiC的电中和能力下降越多；与PAC相比，PASiC具有更快的凝聚絮凝速度和形成更大的絮体；且Al/Si摩尔比越小，PASiC形成的絮体就越大。

The results of ζ-potential test illustrates that the intensity of electrovalent bond was different, resulting in various flocculent morphology, which provided significant evidences for studying flocculent mechanisms of biofloculant.

电位测定结果表明，离子键作用强度不同，致使絮凝形态存在差异，为研究生物絮凝剂的絮凝机理提供了有力的依据。

The results of Zeta-potential test illustrated that the intensity of electrovalent bond was different, resulting in various flocculent morphology, which provided significant evidences for studying flocculent mechanisms of biofloculant.

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 homogeneous nucleation discussion shows that PMSi possesses the excellent homogeneous nucleation performance. Many crystal nucleuses are formatted when PMSi is added into wastewater. It makes lots of floccules sedimentation to format and granule floccules to grow rapidly, which makes the floccules close-grained, big-bodies and fast-sedimentation-rate.

均相成核讨论表明，多核复合无机高分子絮凝剂PMSi具有更强的均相成核能力，大量晶核的形成诱导了絮凝体沉淀的形成，使得絮体颗粒迅速成长，其结果必然是絮体颗粒密实、体积大且沉降速度快。

The result proves that the bioflocculant has a good flocculating activity to suspension of kaoline, fractional flocculation rate is 90%; fractional flocculation rate will be improved on condition of existence of seemly cations.

实验结果证明，培养的复合菌所产的絮凝剂对高岭土悬浮液有相当高的絮凝性能，絮凝率可高达90%；若有适合的金属阳离子助凝，则絮凝率会进一步提高。
