摘要: 在序批式生物膜反应器(SBBR)挂膜前驯化活性污泥对养猪场废水进行生物降解实验。结果表明,在驯化期结束时,COD和NH3-N的去除率分别达到85%和74%。对驯化过程中出现的污泥膨胀、上浮、泡沫等异常现象进行了分析,并提出了相应的解决措施。Abstract: The research is on the biodegradation of the hoggery’s wastewater before the hanging of the microbes to domesticate the activated sludge in a sequencing batch biofilm reactor (SBBR).The results show that the removal rates of COD and NH3-N achieved 85% and 74% respectively at the end of the acclimation period. It also analyses some abnormal phenomenons such as sludge bulking, floating and foam problems in the acclimation process and proposes the corresponding measures.
