摘要
为了探索深度净化猪粪便污水的方法 ,对水葫芦 (Waterhyacinth)深度净化猪粪便污水的效果进行了研究。结果表明 ,水葫芦对猪粪便污水有很好的净化效果 ,在不影响水葫芦生长的前提下 ,单位面积水体生长的水葫芦越多去除禽畜粪便污水COD和NH+ 4 N的效果越好 ,在直径 4 0cm的塑料盆内种植 4 7～ 1 4 0g水葫芦 ,COD和NH+ 4 N去除率分别为 4 8.9%～ 5 8.1 %和 81 .4 %～ 89.9% ;当初始CODcr约为 2 0 0mg/L时 ,水葫芦去除污水CODcr的效果最好 ,去除率为 70 .9% ;在初始污水NH+ 4 N为 34.5～ 1 0 2 .5mg/L范围时 ,初始NH+ 4 N浓度越低效果越好 ,去除率为 90 .7%～ 81 .7% 。
In order to seek the solution for further purification of piggery manure waste water, a study was proposed using water hyacinth. The results showed that there was good purification effect of water hyacinth on piggery waste water. When not affecting growth of water hyacinth, the more water hyacinth planting at unit acreage, the more removal rate of COD and NH + 4 N.Planting 47～140g of water hyacinth in pot 40cm in diameter, the removal rate of COD is 48.9%～58.1%,and NH + 4 N is 81.4%～89.9%.When NH + 4 N of piggery waste water is 34.5～102.5mg/L,its removal rate is 90.7%～81.7%. The water hyacinth is No.1 hydrophyte of oxygenization pool for piggery waste water engineering.
