A Lab scale algal-bacterial membrane photobioreactor (MPBR) was designed and operated under 12-h light and 12-h dark conditions with a light intensity of 8000 lx, in order to investigate the effects of initial concentrations of atrazine, carbon concentration, and hydraulic retention time on the ability of this photobioreactor in simultaneous removal of atrazine and nutrients in the continuous mode. The removal efficiencies of atrazine (ATZ), chemical oxygen demand (COD), phosphorus (PO₄^3--P) and nitrogen (NOx) in optimum condition was more than 95%, 99%, 98% and 97% when the maximum removal rates were 9.5 × 10⁻³, 99.231, 11.773 and 7.762 mg/L-day, respectively. Results showed that the quality of the effluent was reduced by the increase of atrazine concentration. The outcomes on the hydraulic and toxic shocks indicated that the system has a relatively good resistance to the shocks and can return to the stable conditions. Microalgae showed a great deal of interest and capability in cultivating and attaching to the surface of the membrane and bioreactor, and the total biomass accumulated in the system was greater than 6 g/L. The kinetic coefficients of atrazine removal were also studied using various kinetic models. The maximum atrazine removal rate was determined by the modified Stover-Kincannon model. The results approved the ability of the MPBR reactor in wastewater treatment and microalgae cultivation and growth. The decline of atrazine concentration in this system could be attributed to the algal-bacterial symbiosis and co-metabolism process. Accordingly, the MPBR reactor is a practical, simple, economical and therefore suitable process for simultaneous biodegradation of chlorinated organic compounds and nutrients removal from aquatic environments.

设计了实验室规模的藻细菌膜光生物反应器（MPBR），并在光强为8000 lx的12小时光照和12小时黑暗条件下操作，以研究of去津的初始浓度，碳浓度和水力停留时间对这种光生物反应器在连续模式下同时去除at去津和营养素的能力的影响。在最佳条件下，r去津（ATZ），化学需氧量（COD），磷（PO ₄ ^3- -P）和氮（NOx）的去除效率大于95％，99％，98％和97％。去除率是9.5×10 ^-3分别为99.231、11.773和7.762 mg / L-day。结果表明，of去津浓度的增加会降低废水的质量。水力和有毒冲击的结果表明，该系统对冲击具有相对较好的抵抗力，并且可以恢复到稳定的状态。微藻在培养和附着在膜和生物反应器表面上表现出极大的兴趣和能力，并且系统中积累的总生物量大于6 g / L。还使用各种动力学模型研究了去除r去津的动力学系数。最大阿特拉津去除率由改良的Stover-Kincannon模型确定。结果证实了MPBR反应器在废水处理以及微藻培养和生长中的能力。该系统中阿特拉津浓度的下降可能归因于藻-细菌共生和共代谢过程。因此，MPBR反应器是一种实用的，简单的，经济的并且因此合适的方法，用于同时进行氯化有机化合物的生物降解和从水生环境中去除营养物。
