热生物处理法在奶牛场与牛奶加工厂废水COD指标处理效果

为了解热生物处理法在奶牛场与牛奶加工厂废水处理中的应用效果,通过利用在高温条件下发挥高效率的嗜热微生物与常温下具有活性的微生物组合,在相应的容器内进行曝气降解,对水质COD指标进行检测。结果显示:奶牛场和牛奶加工厂的污水经过热—温循环生物处理后,CODcr值明显下降,从初始的2896mg/L和2602 mg/L分别降至800.3 mg/L和870.3 mg/L。结果说明处理效果比较显著,对于牛奶加工厂洗涤用高温废水,尤为适用。

Effect of Thermophilic Biological Treatment on The Wastewater in Dairy Farm and Milk Processing Plant

In order to find out the effect ofthermophilic biological treatment on the wastewater in dairy farm and milk processing plant,a thermophilic bacterium and a common wastewater-treating bacterium were combined to aerobically decompose the wastewater in a series of tanks,and the COD indices of the wastewater were detected after aeration.The results indicated the COD indices of the wastewater de- creased from 2896mg/L and 2602mg/L to 800.3 mg/L and 870.3 mg/L respectively.The findings demon- strated that the effect of thermophilic biological treatment was significant,and especially suitable for the high-temperature wastewater in milk processing plant.
