Abstract

One of the most important quality characteristics associated with wastewater reuse in discharging in water bodies is the microbial quality. This study aimed to determine the efficiency of Médéa wastewater treatment plant (conventional activated sludge system) in the removal of protozoan cysts and parasitic eggs. This study was carried out during four months and samples were collected at weekly intervals from influent and effluent of the wastewater plant. In order to determine the concentration of ova, samples were analyzed according to Bailenger method. The wastewater treatment plant (WWTP) of Médéa has removed 88.9–100% of parasite eggs and more than 95% of protozoan cysts.

摘要

与废水排入水体后再利用相关的最重要质量特性之一是微生物质量。本研究旨在确定美狄亚污水处理厂（传统活性污泥系统）去除原生动物囊肿和寄生虫卵的效率。本研究进行了四个月，每周从污水处理厂的进水和出水采集样本。为了确定虫卵浓度，样本按照贝伦热方法进行分析。美狄亚污水处理厂已去除了88.9%至100%的寄生虫卵以及超过95%的原生动物囊肿。
