摘　　要：试验研究了利用光合细菌处理高含盐有机废水的可行性及其特点。结果表明,在高含盐废水中对光合细菌进行一定时间的驯化,可以得到耐盐能力较强且具有高降解活性的光合细菌菌群,在Cl-的质量浓度为73 g·L-1、COD为3.9 g·L-1时,经过3 d处理,COD的去除率可达77%;光合细菌能快速适应Cl-含量的骤然升降,保证出水水质。This experiment studied the feasibility and feature of treading high salt concentrations organic wastewater by photosynthetic bacteria.The result showed that it could get some photosynthetic bacteria flora which can endure high salt concentration and have high degradation activity by domestication after sometime in high salt concentration organic wastewater.When the chloride concentration was 73 g·L-1,the COD removal rate could reach 77%.When the chloride concentration increased or decreased suddenly,the photosynthetic bacteria could adapt quickly.So the effluent quality wasn＇t influenced.
