A new procedure for virus concentration from water samples has been developed. This method called calcium flocculation-citrate buffer method involves virus flocculation formed by 1 mol/L Ca2+ solution and its flocculating agent, virus release with sodium citrate dissolution (0.3 mol/L, pH5.0), and virus reconcentration by ultrafiltration.

研究建立了一种从水体中浓缩病毒的新方法，即钙离子絮凝-柠檬酸缓冲液洗溶法，该方法的要点是先用一定量的钙离子溶液和钙离子絮凝剂絮凝水体中的病毒，再用pH 5.0的0.3 mol/L的柠檬酸缓冲液洗溶，然后再进一步超滤浓缩。

In this paper, the by-product of titanium white manufacture, FeS04-7H20, is used as the raw materials to study the preparation of composite flocculant based on polyferric.

The results show that proper control of additive, flocculating agent, temperature, stir speed, quantity of each agent and other process parameters could effectively remove the impurities in the coagulation bath such as the solid, big molecules in the forms of undissolved colloid and semi-colloid. The sizes of flocculates are big and loose, ready to precipitate, therefore the impurity removing effect is very ideal, greatly improving the exchange ability of the ion exchange resin in the subsequent process.

研究结果表明在选用合适的添加剂与絮凝剂，适当控制絮凝的温度、搅拌速度、各试剂的添加量和添加顺序等相关工艺参数的条件下，凝固浴中的絮状固体杂质、以未溶解的胶态和半胶态形式存在的大分子性杂质等都被去除，絮凝物块大而疏松，沉降迅速，除杂纯化效果非常理想，大大提高了后续处理工艺中阴阳离子交换树脂的处理能力。

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。

In the tests, the nonionic type polyacrylamide, the anion type polyacrylamide and the zwitterion type polyacrylamide, and the compounding of the poly-aluminum chloride/PHP and the calcium chloride (CaCl2)/NPAM were used as flocculation agents.

选择聚合氯化铝/阴离子型聚丙烯酰胺、氯化钙（CaCl2）/非离子型聚丙烯酰胺组合与NPAM、PHP、两性离子型聚丙烯酰胺作为絮凝剂，在对道清选煤厂水采筛下原生煤泥和浮选尾矿的煤泥水进行组合药剂絮凝实验的基础上，考察了pH对煤泥水絮凝沉降的影响。

The thesis is researched from the three following aspects: the evaluation of quantitative method of flocculation, malt or barley on the effect of premature yeast flocculation, laser and chloridize lithium mutated and selected yeast with appropriate flocculation.
