摘要： The present invention relates to a silver/polydiguanide complex and derivatives thereof including silver and polydiguanide having at least two biguanide moieties, wherein the silver is stabilized in an oxidation state of an integer of 0 to 4, a mole ratio between the silver and the polydiguanide is 1: 1-4, an average particle diameter of the complex is micrometer or nanometer, and zeta potential of the complex is greater than or equal to zero, a preparation method thereof, and an antibacterial composition for burns or wounds treatment including the same as an active ingredient. A silver/polydiguanide complex according to the present invention is different from conventional silver/polydiguanide complexes in carbon, hydrogen, and nitrogen contents as well as in structure of silver and polydiguanide, and solubility, is a material that exhibits a very good antibacterial activity due to a much lower minimal inhibitory concentration (MIC) value by 10 to 100 folds or more compared to silver sulfadiazine which is a conventional therapeutic agent for burns, and may be usefully used as an antibacterial composition for burns or wounds treatment.
摘要翻译：本发明涉及银/聚二胍复合物及其衍生物，其包含具有至少两个双胍部分的银和聚二胍，其中银以0至4的整数的氧化态稳定，银和聚二胍的摩尔比为1：1-4，络合物的平均粒径为微米或纳米，络合物的ζ电位为大于或等于零，其制备方法以及包含其的烧伤或伤口治疗用抗菌组合物作为活性成分。根据本发明的银/聚二胍复合物与碳，氢和氮含量以及银和聚二胍的结构中的常规银/聚二胍络合物不同，并且溶解度是表现出非常好的抗菌活性的材料与作为常规烧伤治疗剂的磺胺嘧啶磺胺相比，低得多的最小抑制浓度（MIC）值为10〜100倍以上，并且可以有效地用作烧伤或伤口治疗的抗菌组合物。

摘要： The invention provides a water purification system comprising a water treatment chamber for the treatment of water by a coagulation and flocculation process comprising an outlet adapted for the discharge of treated water and an outlet adapted for the discharge of flocs generated by the coagulation and flocculation process. The system provides effectively separation of impurities as a floc from the clean water and at the same time avoids the problem of recontamination of the cleaned water by the floc. It is suitable for the purification of bulk quantities of impure water from a variety of sources in a convenient and cost-effective manner, and can be used on a wide scale and even in remote rural locations.
