The experimental results showed that, monochloroacetic acid and dichloroacetic acid enhanced photocatalytic hydrogen generation activity, but trichloroacetic acid did not improve it. The amount of produced H_2 increases almost proportionally to the irradiation time within 5 h irradiation. The photocatalytic oxidation of monochloroacetic acid and dichloroacetic acid mainly produced CO_2, HC1 and CH_2O, the photocatalytic oxidation of trichloroacetic acid mainly produced CO_2 and HCl.

The environmental transport of POPs in Dagu Drainage River selected as a typical example is reasonedly investigated in this article. Characteristics of sediment from DDR in Tianjin are analyzed. The mean value of TOC in sediments is as high as 8%, which is in favor of sorption POPs. The particle sizes of both suspended sediment and bottom sediment are mensurated by Malven Mastersizer. Silt accounts for about 60% in mass, while clay is about 10%. Particles of sediments belong to fine granule. Suspended sediment and bottom sediment mensurated by XRD mainly consist of quartz and illite, both account for 75.5% and 62.2%, respectively. The conformation of suspended sediment is very similar to bottom sediment from SEM photo.
