To study the status and influencing factors of groundwater organic pollution around the Bosten Lake area (Kaidu River-Kongque River Basin), Xinjiang, China, the pollution index method was applied to 82 groundwater samples and 15 lake water samples for comprehensive pollution evaluation. Results showed that the detection rates of organic pollutants in groundwater and lake water samples in the study area are 24.4% and 6.7%, respectively, but all the water samples have concentrations of organic pollutants less than the standard water quality limits. There are 11 unpolluted groundwater samples, 8 mildly polluted groundwater samples and one mid-polluted groundwater sample, accounting for 13.4%, 9.8% and 1.2% of total groundwater samples, respectively. The detection points of groundwater organic pollutants in the study area are mainly distributed in the piedmont plain area in the northern Yanqi Basin, the Yanqi County and the northwestern plain area of Bosten Lake. Some points sporadically distributed in the urban area in Korla. Groundwater organic pollution around the Bosten Lake area is mainly affected by industrial pollution, agricultural pollution, domestic pollution, vadose zone lithology, surface water quality and land utilization type.

Photocatalytic degradation of waste pollutants using TiO2is a promising technology. Recently, the use of bentonite for the removal of organic pollutants was widely studied because of large specific surface areas. Studies have shown that TiO2supported on bentonite, or TiO2/bentonite composite, exhibits bifunctionality of adsorption and photo catalysis in synergism. This paperpresents a literature review of the preparation and modification techniques of bentonite/TiO2composite photocatalyst, and their characteristics. The review will also focus on the current researches on the degradation of water organic pollutants by using bentonite/TiO2composite photocatalyst and its key influencing factors.

This formation of bromate during ozonation of polluted source water has long caused great concerns. This paper used KMnO4 to control the bromate formation during water ozonation. KMnO4 was added 10 min prior ozone to oxidize the organic pollutants. The initial Br- concentration was 1000 μg/L. The results showed that the bromate formation efficiency was low (<5%) during KMnO4-ozone oxidation. Among KMnO4 dose, ozone dose, and source water TOC, the single most important factor for bromate formation was the ozone dose. When the ozone dose was 3 mg/L or higher, the bromate concentration exceeded the national standard no matter what level of KMnO4 was used. The organic pollution level had little influence on the bromate formation.
