摘要

灰水是替代淡水标准化使用的重要资源。使用经过处理的灰水可以减少水的消耗和污染物进入环境。然而，如果不及时治疗，可能会很危险。本研究考察了由一级过滤器、曝气器、二级过滤器和紫外线消毒装置组成的灰水处理系统的效率。在考察了灰水的特性后，分析了该系统对pH、TSS、BOD、COD、ABS和总大肠菌群参数的去除效果。然后，将该系统处理的灰水与伊朗的环境标准进行了比较。处理后的灰水的pH值为7.5–7.6。该系统去除BOD和COD参数的效率分别为98–100和76–100%。该系统消除ABS参数的效率为96–97%。此外，该系统能够以100%的效率消除总大肠菌群。结果表明，在该系统上进行的三系列实验中，根据伊朗标准，处理后的废水适用于灌溉和农业用途。然而，该系统无法获得有关地表水和吸收井排放的COD参数的许可。

Evaluation of the efficiency of a gray water treatment system based on aeration and filtration

Gray water is a great resource for replacing fresh water to be used in standardized usages. The use of treated gray water reduces water consumption and the entry of pollutants into the environment. However, if left untreated, it can be dangerous. The present study examines the efficiency of a gray water treatment system consisting of primary filter, aeration, secondary filter and ultraviolet disinfection unit. After examining the characteristics of gray water, the efficiency of this system was analyzed to remove the pH, TSS, BOD, COD, ABS and total coliform parameters. Then, the gray water treated through this system was compared with the environmental standard of Iran. The pH of the treated gray water was 7.5–7.6. The efficiency of this system for removing the BOD and COD parameters was 98–100 and 76–100%, respectively. This system had an efficiency of 96–97% to eliminate the ABS parameter. Also, this system was able to eliminate total coliform with 100% efficiency. Results showed that in the three series of experiments performed on this system, according to the Iranian standard, the treated wastewater is suitable for irrigation and agricultural uses. However, this system could not be licensed for the COD parameter regarding the discharge to surface water and absorbent wells.
