چکیده مقاله:

The integrated system anaerobic reactor high rate algal pond (AR-HRAP) is an extensive treatment of the wastewater system which has many advantages, namely, a low occupation of land, possible energy self-sufficiency and a low cost of investment. In order to optimize the design of the system and adapt it to the regional context, we developed a design model based on the balance sheets of removing organic matter. This model is based on an engineering concept as taking into account the parameters of reactor design (flow rate, load, and retention time). However, this model ignores the night period during which photosynthesis does not take place; this can lead to oversize reactors. Therefore, this model was performed by introducing an operating coefficient 0 which represents the ratio of oxygen consumption in daytime and night. This model approaches and checked for retention time of 1.5 to 2 days in an anaerobic reactor and 3 to 4 days in the HRAP. The incoming raw organic loads to the system were in the order of 550 mg.l-1. The comparative study of the theoretical and experimental results confirms the interest of such approach.
