摘要
纳米铁具有优良的污水微生物处理性能,利用纳米铁水处理的自动控制系统可有效提高污水处理的效率。基于所设计的纳米铁水处理系统,以单片机为系统控制核心,设计搭建了系统软硬件。通过对采集的4种样品分别进行污水处理实验,结果表明纳米铁对微生物具有很强的吸附作用;对比2mg/mL和3mg/mL 2种浓度纳米铁的水处理效果可知,采用浓度较高的3mg/mL纳米铁可获得更好的水处理效果;研究搭建的自动控制系统能可靠实现纳米铁对污水高效率的自动处理。
Iron nanoparticles have perfect capability of inactivating microbial. The automatic control system using iron nanoparticles can effectively improve the sewage treatment efficiency. Design of the whole system is completed. In this system, single chip microcomputer is used as control core. After sewage treatment experiment of four samples collected, it indicales that iron nanoparticles have a strong adsorption on microorganism. Comparing 2mg/mL and 3mg/mI. iron nanoparticle suspension, the suspension with higher concentration of 3mg/mL can obtain better treatment effect. The iron nanoparticle processing system in this research can realize reliable automatic sewage treatment with high efficiency.
