摘要

本研究的目的是对2020年摩洛哥埃拉奇迪亚市污水处理厂的未经处理和净化废水进行物理化学和细菌学表征，以评估废水处理的有效性。污水处理厂的曝气泻湖型，并将其重新用于灌溉。2020年1月至12月对处理后的废水进行的物理化学分析的月平均结果如下：BOD5=94.45 mgo2/l；COD=339.32 mgo2/l；SS=87.67 mg/L。结果表明，摩洛哥地表水排放符合一般限值，保护了环境。因此，细菌学结果显示存在各种细菌，其中粪便大肠菌群（CF）为680CFU/100ml；总大肠菌群（CT）为2810 UFC/100，粪链球菌为46 UFC/100 ml，仍低于摩洛哥灌溉标准建议的限值（CF<1000 UFC/100 ml），这允许它们在灌溉中被利用和重复使用。

Evaluation of Wastewater Quality Treated by the Step of the City of Errachidia (Morocco)

The objective of this study is the physico-chemical and bacteriological characterisation of raw and purified wastewater from the WWTP of the city of Errachidia, Morocco, during the year 2020, in order to evaluate the effectiveness of wastewater treatment. of the wastewater treatment plant, of the aerated lagoon type, and see their reuse in irrigation. The average monthly results of the physico-chemical analyses of treated wastewater carried out from January to December 2020 are as follows: BOD5 = 94.45 mgo2/l; COD = 339.32 mgo2/l; SS = 87.67 mg/L. The results show compliance with the general limit values for the discharge of Moroccan surface water, which protects the environment. Thus, the bacteriological results show the presence of various germs with average annual values where faecal coliforms (CF) are 680 CFU/100 ml; total coliforms (CT) are 2810 UFC/100 and faecal streptococci are 46 UFC/100 ml, which remain below the limit values recommended by Moroccan irrigation standards (CF < 1000 UFC/100 ml), which allows their exploitation and their reuse in irrigation.

期刊介绍： Asia, as a whole region, faces severe stress on water availability, primarily due to high population density. Many regions of the continent face severe problems of water pollution on local as well as regional scale and these have to be tackled with a pan-Asian approach. However, the available literature on the subject is generally based on research done in Europe and North America. Therefore, there is an urgent and strong need for an Asian journal with its focus on the region and wherein the region specific problems are addressed in an intelligent manner. In Asia, besides water, there are several other issues related to environment, such as; global warming and its impact; intense land/use and shifting pattern of agriculture; issues related to fertilizer applications and pesticide residues in soil and water; and solid and liquid waste management particularly in industrial and urban areas. Asia is also a region with intense mining activities whereby serious environmental problems related to land/use, loss of top soil, water pollution and acid mine drainage are faced by various communities. Essentially, Asians are confronted with environmental problems on many fronts. Many pressing issues in the region interlink various aspects of environmental problems faced by population in this densely habited region in the world. Pollution is one such serious issue for many countries since there are many transnational water bodies that spread the pollutants across the entire region. Water, environment and pollution together constitute a three axial problem that all concerned people in the region would like to focus on.
