Abstract

Abstract

Reclaimed water has the outstanding advantages of easy to obtain, large quantity, stable and high resource availability, and is gradually becoming an important source for landscape water. However, reclaimed water contains nutrients such as nitrogen and phosphorus, therefore exacerbates the risk of algal blooms during landscape reuse. UV-C irradiation can suppress algal growth for several days in the early growth stage, thereby is proposed as an approach for preventing algal blooms. In this study, the secondary effluent from a sewage treatment plant in Shenzhen was taken as a typical sample of reclaimed water for landscape, and the growth suppression effect of UV-C (254 nm) on a typical Chlorophyta species, Scenedesmus obliquus were investigated. The effect of UV-C doses on growth characteristics, cell membrane integrity and photosynthetic activity of S. obliquus were assessed by a flow cytometry and a PHYTO-PAM chlorophyll fluorometer. The results showed that for S. obliquus, with an initial density of about 7×10⁴ cells/mL, UV-C irradiation at 50~100 mJ/cm² achieved a growth inhibition period of 1~5 d, and the growth inhibition period could be further extended to 10 days at UV-C doses of 150~200 mJ/cm². UV-C irradiation caused marked decreases in photosynthetic activity of S. obliquus immediately and caused rupture of part of the cells gradually, and the percentage of membrane damaged cells increased to 16%~71% within 10 days after 100~200 mJ/cm² UV-C treatment. In summary, UV-C could achieve significant suppression effect on S. obliquus growth, which was a promising method for preventing and controlling the bloom risk of S. obliquus in reclaimed water.
