钛（Ti）天然存在于土壤中，并作为高纯二氧化钛（TiO 2）在许多商业产品中使用了数十年。我们报告的第一次发生，表征和去除纳米和较大尺寸的钛在污水处理厂（WWTPs）。在详细研究的一个污水处理厂，原污水含有100至近3000 μ g Ti/L的Ti大于0.7 μ m占原污水中的Ti的大部分，这部分被很好地去除污水处理厂的过程。该污水处理厂和其他几个污水处理厂的流出物中的钛浓度范围为
Titanium (Ti) occurs naturally in soils and as highly purified titanium dioxide (TiO2) in many commercial products that have been used for decades. We report for the first time the occurrence, characterization, and removal of nano- and larger-sized Ti at wastewater treatment plants (WWTPs). At one WWTP studied in detail, raw sewage contained 100 to nearly 3000 mu g Ti/L Ti larger than 0.7 mu m accounted for the majority of the Ti in raw sewage, and this fraction was well removed by WWTP processes. Ti concentrations in effluents from this and several other WWTPs ranged from
