摘要
未经处理的畜禽污水是一种典型的高氨氮、高有机物浓度的废水,会导致一系列危害,用ABR-改良SBR联合工艺对其进行处理可使出水达到农灌标准。对该工艺厌氧段控制步骤的启动进行了研究。结果表明,对HRT等因素进行合理控制可以加快系统的启动;启动达到设计负荷后,可获得72%的CODcr去除率。
As one typical high strength wastewater with high ammonia, the wastewater from the scaled farm is in rich of ammonia and phosphorus, which will result in a series of adverse effects. ABR followed by modified SBR can meet the need of swine manure treatment. The starts-up of the ABR was studied, HRT, CDDcr concentration in the influent, reactor sequence （especially the settle）, nitrified liquid recycle were designed to be four variables and the removal rate of CODcr achieved 72 %.
