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.

水消毒对于保护公众健康非常重要。最流行的工艺是用氯和其他相关化学品进行处理，但三卤甲烷和其他致癌物质的形成是该工艺的严重缺陷。据报道，这些有机卤素化合物会发生生物缩合，从而导致严重的环境污染。该实验室最近的一份报告表明，不溶性吡啶鎓型树脂通过与表面的许多细菌细胞接触而强烈捕获它们。本研究项目的目的是开发一种基于不溶性吡啶鎓型树脂的新型、可靠、有效的水中微生物去除工艺，该工艺不产生任何有毒化学物质，也不对环境造成污染。树脂的捕获能力随着树脂中吡啶鎓基团含量的增加而增加，基质中树脂的亲水性和在水中的溶胀度也随之增加。疏水性细菌和亲水性细菌在树脂和细菌细胞之间的捕获相互作用方面表现出明显的差异。对于疏水性细菌，树脂和细胞之间的静电相互作用和疏水相互作用似乎很重要。对于亲水性细菌，提出了其他因素，例如溶剂（水）介导的力和水动力。另一方面，发现相应的线性聚合物，即可溶性吡啶鎓型聚合物表现出抗菌活性。另外，可溶性吡啶鎓类聚合物是。被发现是一种用于微生物细胞悬浮液的优异聚合物凝固剂。这些现象似乎与吡啶鎓型树脂捕获微生物细胞的能力强有关。基于这些实验观察，不溶性吡啶鎓型树脂被证明是一种从废物中去除微生物的优异材料，不会产生有毒化学物质（如三卤甲烷），并且不会污染环境。较少的
