摘要： The present invention is directed to a biocidal water treatment composition, water treatment apparatus, and method of treating water to reduce levels of pathogens. The composition contains sources of copper, zinc, and silver metal ions within a crosslinked polymer matrix. Examples of these ion sources include copper sulfate, zinc sulfate, and silver nitrate. An example of the crosslinked polymer matrix is crosslinked chitosan, which also serves to clarify the water and release the metal ions over time. The product is easy to manufacture, and allows the use of decreased halogen sanitizer, as well as decreased copper ion, thereby decreasing the likelihood of staining. The product simultaneously provides good bactericidal and algaecidal properties, despite low levels of copper ion and low chlorine levels.
摘要翻译：本发明涉及一种生物杀灭水处理组合物，水处理装置和处理水以降低病原体水平的方法。该组合物含有交联聚合物基质中铜，锌和银金属离子的来源。这些离子源的实例包括硫酸铜，硫酸锌和硝酸银。交联聚合物基质的实例是交联的壳聚糖，其还用于澄清水并随时间释放金属离子。该产品容易制造，并允许使用减少的卤素消毒剂，以及减少的铜离子，从而降低染色的可能性。该产品同时提供良好的杀菌和除藻性质，尽管铜离子含量低，氯含量低。
