栅藻和小球藻在4种养殖废水中的生长及净化效果对比研究
A comparative study on growth and purification efficiency of Scenedesmus obliquus and Chlorella vulgaris in four kinds of breeding wastewater
摘要
Abstract
Scenedesmus obliquus and Chlorella vulgaris were cultivated in processed chicken-house breeding wastewater,piggery biogas slurry (PBS),pond wastewater,and BG-11 medium,in order to compare their growth in various culture media,the purification effect on nitrogen and phosphorus in wastewater,and the accumulation of lipids by the two strains of microalgae.Results show that during 23 d of cultivation,0.353 1 g · L-1 and O.189 8 g · L-1 of dry algae powder were obtained from C.vulgaris + PBS andc.vulgaris + BG-11 respectively,which were higher than yields in other media.In the S.obliquus group,S.obliquus + BG-11 obtained the most algae powder (0.168 5 g · L-1),followed by S.obliquus + PBS (0.131 1 g · L-1).The two microalgae strains had different purification effects on varied wastewater media,but overall the removal effect of C.vulgaris and S.obliquus on total phosphorus was highest,reaching 89.32% to 98.69%.In addition,the nitrate nitrogen removal rate was over 60%.Finally,C.vulgaris cultivated in PBS had the highest lipid content (50.34%);the lipid content of S.obliquus cultivated in PBS was close to that in BG-11,and higher than those in other media.Therefore,it is feasible to cultivate C.vulgaris and S.obliquus in PBS.关键词
