New Method for Removal of Microorganisms from Water Based on Pyridinium-Type Resin

水消毒对保护公众健康很重要。最流行的方法是用氯和其他相关化学品处理，但三卤甲烷和其他致癌物的形成是这种方法的一个严重缺陷。据报道，这些有机卤素化合物会发生生物缩合，对环境造成严重污染。该实验室最近的一份报告表明，不溶性吡啶型树脂通过与表面的细菌细胞接触，强烈地捕获了许多细菌细胞。本课题旨在开发一种不产生任何有毒化学物质、不污染环境的不溶性吡啶型树脂去除水中微生物的可靠、有效的新工艺。树脂的捕获能力随着树脂中吡啶基团含量的增加而增加，树脂的亲水性和在水中的高度溶胀性也随之增加。疏水细菌和亲水细菌在树脂与细菌细胞的相互作用中表现出明显的差异。对于疏水细菌，静电相互作用和树脂与细胞之间的疏水相互作用显得很重要。对于亲水细菌，溶剂（水）介导力和水动力力等其他因素也被认为是影响细菌生长的因素。另一方面，发现相应的线性聚合物，即可溶性吡啶型聚合物具有抗菌活性。此外，水溶性吡啶型聚合物是。被发现是一种极好的微生物细胞悬浮液聚合混凝剂。这些现象似乎与吡啶型树脂捕获微生物细胞的能力强有关。基于这些实验观察，不溶性吡啶型树脂被证明是一种去除废水中微生物的优良材料，不产生有毒化学物质，如三卤甲烷，并且不会污染环境。少

Water disinfection is important in the protcetion of public health. The most popular process is the treatment with chlorine and other related chemicals, but the formation of trihalomethanes and other carcinogens is a serious defect in this procedure. These organohalogen compounds are reported to undergo biocondensation, which results in a serious pollution of the environment. A recent report from this labolatory has demonstrated that insoluble pyridinium-type resin strongly captures many bacterial cells on the surface by contact with them. The purpose of this research project is to develop a new, reliable, and effective process for termoval of microorganisms from water based on the insoluble pyridinium-type resin, which does not produce any toxic chemical substances and does not exert pollution upon the environment. The capturing ability of the resin increased with the content of the pyridinium group in the resin, as well as hydrophilicity and high degree of swellin in water of the res … More in matrix. Hydrophobic bacteria and hydrophilic bacteria showed distinct difference in the capturing interaction between the resin and bacterial cells. With hydrophobic bacteria, electrostatic interaction and hydrophobic interaction between the resin and cells appeared to be important. with Hydrophilic bacteria, other factors such as solvent (water) mediated forces and hydrodynamic forces were suggested. On the other hand, the corresponding linear polymer, i.e., soluble pyridinium-type polymer was found exhibit antibacterial activity. In addition, the soluble pyridinium-type polymer was. found to be an excellent polymeric coagulant for the suspension of microbial cells. These phenomena appeared to be related with the strong ability of the pyridinium-type resin to capture microbial cells. Based on these experimental observations, the insoluble pyridinium-type resin was demonstrated to be an excellent material for removal of microorganisms from waster without production of toxic chemicals such as trihalomethanes, and with31t environmental pollution.
