光合细菌配合UASB处理高盐度有机废水的研究

海产品加工产业在沿海城市日益发展,光合细菌以其广泛适应性成为近年来污水处理中的常用方法,从海水中分离培养的光合细菌具有很高的耐盐性.研究了光合细菌配合UASB工艺处理高盐度有机废水的可行性,按12%,24%,36%海水比例的梯度逐步提高进行驯化运行试验,并探讨了盐度对有机物降解的影响,确定了该处理系统的运行参数.

Study on the Photosynthetic Bacteria with UASB Process Treatment of High-Salinity Organic Wastewater

The marine product industry develops rapidly in seaside regions.In recent years,photosynthetic bacteria along with their wide adaptability are commonly used in sewage treatment.The photosynthetic bacteria which are isolated from the sea have a high salt tolerance.A feasibility study of the photosynthetic bacteria with UASB Process treatment of high-salinity organic wastewater is presented in this paper.With the concentration of seawater proportion gradually（12%,24%,36%）increasing,the gradient acclimatization is tested to explore the effect of salinity on the degradation of organic matter and to determine the biological contact oxidation system operating parameters.
