摘要

The technique of aeration can only partly treat pig slurry because of its limited effect on much of the undissolved matter present. Further reduction in the environmental impact of the effluent, thus requires some form of physical clarification. Centrifugation tests showed the extent to which physical separation could concentrate a range of insoluble slurry components into a sludge, leaving a clarified supernatant effluent. These insoluble components included suspended solids (TSS), Chemical Oxygen Demand (GOD), copper, zinc, and manganese; the effect of separation on the Total Solids concentration (TS) was less owing to its partial solubility.
