Gongye shui chuli, 2013 从白酒废水活性污泥中筛选得到一株高效微生物絮凝剂产生菌,其絮凝活性为54.9%。利用均匀试验设计和回归分析,建立数学模型,得到最佳絮凝培养条件。试验结果表明,最佳絮凝条件:初始pH(X3)=9.1,葡萄糖质量浓度(X1)为30 g/L,尿素质量浓度(X2)为2.14 g/L;各因素与絮凝活性关系的数学模型为Y=-99.653+1.495X1+32.103X2+25.602X3-0.023X12-7.497X22-1.392X32。在最佳絮凝培养条件下,该微生物絮凝剂产生菌的实际絮凝活性可达73.8%。

Gongye shui chuli, 2014 通过测定石油磺酸盐（TRS）对絮凝体系下清液透光率、絮体上升速率、滤过速率及絮体形态的变化，研究了TRS对杂化絮凝剂PAFSi-PAM+絮凝作用的影响。结果表明：TRS增加了钻井废水中胶体粒子的Zeta电位，从而增加了絮凝难度。当TRS质量分数超过0.3%时，TRS与PAM+可形成稳定的复合物，絮体上升速率及絮凝体系的滤过速率均高于其他体系，且由于TRS的高分散能力，将导致絮体剥落，使体系的絮凝效果变差。

Gongye shui chuli, 2012 以氯化锌、氯化铝、盐酸和聚丙烯酰胺为主要原料，制备了无机-有机锌基复合絮凝剂。以浊度去除率为考察指标，探讨了制备过程中ZnCl2、AlCl3、PAM 和HCl的投加量对锌基复合絮凝剂絮凝效果的影响。结果表明，锌基复合絮凝剂的最佳制备条件：ZnCl2质量分数为10%，AlCl3质量分数为10%，PAM 质量分数为0.015%，HCl 质量分数为3%。与铝盐复合絮凝剂和铁盐复合絮凝剂相比，锌基复合絮凝剂具有絮凝沉降快、污泥体积小等特点。

Gongye shui chuli, 2010 从中北大学生活污水中筛选得到一株稳定高效的微生物絮凝剂产生菌,初步鉴定该菌株为韦荣氏菌(Veillonellaceae Rogosa-W23)。该菌株适宜培养温度为35℃,最适pH=8.0,最佳碳源为葡萄糖。Veillonellaceae Ro-gosa-W23所产微生物絮凝剂成分鉴定为还原性糖。该微生物絮凝剂对高岭土悬浮液的絮凝率可达95.1%。絮凝对比试验发现:该絮凝剂优于高分子絮凝剂PAC,其对黄土悬液、纳米级铜-碳-石墨悬液也有良好的絮凝效果。
