Abstract

Results of laboratory studies of anaerobic lagoon performance have been analyzed to yield kinetic data applicable for design. None of the models currently used fitted the data. A novel interpretation has been proposed based on the dependence of effluent quality on volumetric organic loading. It is suggested that the removal takes place in consecutive stages at a progressively decreasing rate (expressed in kg m−3 day−1). In the case of dilute piggery wastes from large farms the first stage of rapid sedimentation takes only a few hours and achieves some 55% removal of COD. The second stage, biochemical removal, proceeds at 1·7 kg COD m−3 day−1 for about 3 days HRT and then the removal rate drops down to 0·2kg COD m−3 day−1

厌氧泻湖中养猪场废物处理动力学
对厌氧泻湖性能的实验室研究结果进行了分析,得出了可用于设计的动力学数据。目前使用的模型都不能拟合数据。一种新的解释提出了基于依赖的流出水质的体积有机负荷。这表明,去除以逐渐降低的速率(以kg m−3天−1表示)连续阶段进行。对于来自大型养猪场的稀释猪舍废物,第一阶段的快速沉淀仅需几个小时,COD去除率约为55%。第二阶段,生化去除,以1.7 kg COD m−3 day−1进行,HRT约为3天,然后去除率降至0.2 kg COD m−3 day−1
