摘要

从纳米TiO2颗粒的聚集以及对水体粘度和沉降性能的影响等方面研究纳米TiO2颗粒物在水中的环境行为

实验发现纳米颗粒物TiO2进入水体会发生快速团聚

而且颗粒物质量浓度越大

团聚越快.纳米颗粒物还会改变水体流动特性和沉降性能

这种改变受原水水温、pH值等因素的影响.结果表明纳米TiO2颗粒对低温、pH值中性的原水影响更大.

Abstract

The environmental behavior of nano-sized TiO2 in water source is studied in the accumulation of particles and the influence on viscosity and settling.The larger the particle concentration is

the faster accumulation happens.Nano-sized TiO2 added to water would change the flow and settling characteristics of water

which is affected by temperature and pH value.It is also shown that nano-sized TiO2 has more effect on low temperature and neutral pH water source.
