1. The pattern and flocculent mechanism of PSFZB were studied by using XRD instrument analysis method and electrophoretic mobility measurement.

2. Understanding and grasping the characteristics of flocculent and flocculation mechanism. Determining the optimum conditions for flocculation.

3. In the make - up chamber auxiliary flocculent is poured in with water.

4. A flocculent mass formed in a fluid through precipitation or aggregation of suspended particles.

5. In addition , the preparation and the mechanism of magnetic flocculent are elucidated in the paper.

6. The advanced prospect and research aspect of modified starch flocculent were predicted.

7. With the three - chamber flow - through plant, you will throw away 20 % of the auxiliary flocculent.

7. try its best to collect and make good sentences.

8. The dispersive force caused by collision of coarse particles reduces to a great degress due to the cushioning effect of the flocculent structures formed by fine particles.

9. Fine - ray, 2 ranks mainly under themicroscope. chocolate colored, board wax mask texture , Chord Flocculent mask pattern.

10. The study shows that the free ring - like polymer has more advantage on flocculent destruction.
