This study aims at treatment of grey water for irrigation, focusing on a treatment technology that is robust, simple to operate and with minimum energy consumption. The result is an optimized system consisting of an anaerobic unit operated in upflow mode, with a 1 day operational cycle, a constant effluent flow rate and varying liquid volume. Subsequent aerobic step is equipped with mechanical aeration and the system is insulated for sustaining winter conditions. The COD removal achieved by the anaerobic and aerobic units in summer and winter are 45%, 39% and 53%, 64%, respectively. Sludge in the anaerobic and aerobic reactor has a concentration of 168 and 8 mg VSL(-1), respectively. Stability of sludge in the anaerobic and aerobic reactors is 80% and 93%, respectively, based on COD. Aerobic effluent quality, except for pathogens, agrees with the proposed irrigation water quality guidelines for reclaimed water in Jordan.
本研究旨在处理灰水用于灌溉，重点关注一种稳健、操作简单且能耗最低的处理技术。结果是得到了一个优化系统，该系统由以升流模式运行的厌氧单元组成，运行周期为1天，出水流量恒定但液体体积可变。后续的好氧步骤配备机械曝气，并且该系统进行了保温以维持冬季条件。厌氧和好氧单元在夏季和冬季实现的化学需氧量（COD）去除率分别为45%、39%和53%、64%。厌氧和好氧反应器中的污泥浓度分别为168和8毫克挥发性悬浮固体（VSL）/升。基于COD，厌氧和好氧反应器中污泥的稳定性分别为80%和93%。除病原体外，好氧出水水质符合约旦再生水拟议的灌溉水质准则。
