  • 摘要: 采用A2/O生物接触氧化工艺处理屠宰加工废水,在实现有机物高效去除的前提下,对缺氧反硝化HRT、好氧硝化HRT、混合液回流比、溶解氧和进水氨氮负荷等因素对脱氮效果的影响进行了研究。结果表明,在好氧HRT和缺氧HRT分别为18 h和8 h,混合液回流比为200%,好氧柱内的DO为2.5~3.5 mg/L时,系统对氨氮和TN的平均去除率分别达到94%和68%以上。在原水氨氮负荷不超过0.109 kg/(m3·d)的情况下,出水水质均达到了广东省《水污染排放限值》(DB44/26-2001)第二时间段一级标准。
    Abstract: A2/O biological contact oxidation process was used to treat slaughter-process wastewater. On the premise of achieving the efficient removal of organic matter, the influences of the factors were studied on denitrification, such as, anoxic denitrification HRT, aerobic nitrification HRT, mixed liquor recycle ratios, DO and the influent loading of ammonia-nitrogen. The results showed that when anoxic HRT and aerobic HRT were 18 h and 8 h, respectively, the mixed liquor recycle ratio was 200%, DO in the aerobic zone was 2.5~3.5 mg/L, the average removal rates of ammonia-nitrogen and TN were more than 94% and 68%, respectively. Under the condition of the raw water, ammonia-nitrogen load was less than 0.109 kg/(m3·d), the effluent quality met the first class discharge standard of second period level of Water Pollution Discharge Limits of Guangdong Province(DB44/26-2001).
