| 摘 要： | 采用添加蚯蚓的毛细管渗滤沟A和没有蚯蚓的毛细管渗滤沟B对生活污水处理进行对比实验研究,同时考察毛细管渗滤沟中蚯蚓的数量变化和添加蚯蚓对土壤结构的影响。实验结果表明：蚯蚓对毛细管渗滤沟处理有机物有促进作用,蚯蚓的加入可以改变土壤结构,提高土壤孔隙率,增加出水溶解氧。反过来,毛细管渗滤沟为蚯蚓生存、繁殖提供了适宜条件,在土...

| Abstract: | Two types of capillary infiltration(A: with earthworm;B: without earthworm) were used to treat domestic sewage.The influence of the number change and the existence of earthworm on the soil structure were investigated as well.The results showed that earthworm could increase the dissolved oxygen of the effluent and increase the removal efficiency of organic matter.Besides,the soil porosity was improved with the addition of the earthworm.Conversely,capillary infiltration provided a suitable condition for the e... |
