Degradation of organic pollution aerated lagoons. In an arid climate: the case the treatment plant Ouargla (Algeria)

The aim of the present work is to follow up and analyze the purgation performances of wastewater treatment plant (WWTP) by aerated lagoons, used to treat wastewater from Ouargla city, and ensure the reliability of the sewage sector in the studied area. The obtained yields for suspended solids (SS) vary from 23.50 to 92.12%. During the year 2013 the average yield varied between 63.63 and 87.40% for the biochemical oxygen demand BOD5 and between 43.34 and 92.21% for the chemical oxygen demand COD.

Chinese abstract目前工作目标是跟踪分析污水处理厂使用氧化塘处理Ouargla城镇废水的纯化效果,以及检测研究区域内的污水处理阀的可靠性。通过MES,Ouargla各处理站的纯化率在23.50%–92.12%之间。2013年平均纯化率范围为63.63%–87.40%,化学需氧量COD范围为43.34%–92.21%。.关键词: Ouargla, 废水, 处理, 氧化塘, 纯化率
