概要	A tubular-type solar photoreactor system powered by com. solar panels and consisting of six 20-tube modules (Pyrex glass) to mimic a pilot plant scale configuration was designed and constructed to examine the remediation of simulated wastewaters contaminated with various classes of org. pollutants such as endocrine disruptors (e.g. bisphenol A), anionic surfactants (sodium butylnaphthalenesulfonate and sodium dodecyl- benzenesulfonate), herbicides (e.g. 2,4-dichlorophenoxyacetic acid) and a com. dishwasher detergent. Photo-oxidative processes followed first-order kinetics expressed in terms of the total light energy (in kJ) that impinged on the photoreactor. The influence of TiO2 loading and circulation flow rate of the wastewaters on the dynamics of the photo-oxidn. to mineralization (loss of total org. carbon, TOC, or formation of sulfate ions) was investigated. The optimal operational parameters were: TiO2 loading, 2 g L-1; circulation flow rate, 7.5 L min-1.
