摘要
在低温条件下,进行了厌氧折流板反应器(ABR)处理生活污水的试验研究。结果表明,在温度为9~19℃、水力停留时间(HRT)为24h的条件下,ABR对生活污水具有良好的处理效果,对COD的平均去除率为65.5,对SS的平均去除率为88.1,说明ABR反应器在低温下具有去除有机污染物的巨大潜能和广阔的应用前景。研究结果还表明,当温度<13℃时,进水有机负荷的变化对ABR的除污性能影响较大(进水有机负荷越大则对COD的去除率越低);当温度>16℃时,进水有机负荷的变化则不会对ABR的除污效果造成影响,且随进水有机负荷的增加,ABR的除污能力不断得到加强。
The treatment efficiency of domestic sewage by anaerobic baffled reactor (ABR) reactor was investigated under low temperature condition. The results show that under the conditions of temperature of 9 to 19 ℃ and hydraulic retention time (HRT) of 24 h, the treatment efficiency of domestic sewage by ABR is good, and the removal rates of COD and SS are 65.5% and 88.1% respectively, which demonstrate that ABR has tremendous potential and wide application prospect in treatment of organic contaminants under low temperature condition. When the temperature is less than 13 ℃, the influent organic loading has a large influence on treatment of domestic sewage by ABR. The removal rate of COD is decreased with increasing of the influent organic loading. When the temperature is more than 16℃, the influent organic loading has no influence on treatment of domestic sewage by ABR. The pollutant removal efficiency of ABR is enhanced when the influent organic loading is increased.
