Abstract

Household or office wastewater consists of two parts of faecal and non-faecal wastewater. Non-faecal section, which accounts for more than 60% of household wastewater, is known as grey water. Treating this part of sewage and using it in various areas can greatly reduce the consumption of potable water. In this research, three methods of advanced oxidation processes including Fenton, UV/H2O2, and UV/TiO2 were investigated for treatment of two grey water sourced from Shif Island and Persian Gulf University restaurant in Bushehr province of Iran. These grey waters were highly polluted with COD content of 600 mg/L and 1400 mg/L, respectively. The efficiency of each process was determined by measuring the COD removal rate. Results showed that at optimum reaction conditions, the COD removal efficiency of the UV/H2O2 process was the best, compared to the other two processes. The COD removal efficiency of UV/H2O2 process at pH = 3 and H2O2 = 1500 and 750 mg/L for grey water of the Shif Island and Persian Gulf University restaurant were 88% and 90%, respectively. Therefore, the treated gray waters can be reused economically.

Fenton、UV/H2O2和UV/TiO2工艺处理高污染灰水

家庭或办公室废水由粪便废水和非粪便废水两部分组成。非粪便部分占家庭废水的60%以上，被称为灰水。处理这部分污水并将其用于各个地区可以大大减少饮用水的消耗。本研究采用Fenton、UV/H2O2和UV/TiO2三种先进氧化工艺处理伊朗布什尔省Shif岛和波斯湾大学餐厅的两种灰水。这些灰色水域受到严重污染，COD含量分别为600 mg/L和1400 mg/L。通过测量COD去除率来确定每个工艺的效率。结果表明，在最佳反应条件下，UV/H2O2工艺对COD的去除效果最好。在pH=3、H2O2=1500和750mg/L条件下，UV/H2O2工艺对Shif Island和波斯湾大学餐厅灰水的COD去除率分别为88%和90%。因此，处理后的灰水可以经济地重复使用。
