污水蚯蚓土地处理与资源回归

Land Treatment of Sewage by Earthworm and Regression of Resources

利用蚯蚓的生态污水土地处理与利用土壤中生物膜的常规污水土地处理的不同之处在于：利用蚯蚓的生态污水土地处理不仅处理污水而且改良土壤。污水中的水分部分可直接用于灌溉，部分蒸发到大气中还利于调节区域小气候。这一处理方法可实现资源的良性循环和再生，在处理过程中养殖的蚯蚓还是一种富含蛋白质的饲料源。

The land treatment of sewage by earthworm can be called Ecological Land Treament.The difference between the land treatment by the worm and traditional land treament by biological film is that the land treatment by the worm not only can treat sewage but also improve the soil.Some water in sewage can be applied to irrigation and the others can be evaporated to air to adjust the climate of the small area.This treatment can have resources recirculated and regenerated in a good state.The worm got from the treatment is also a kind of forage with high protein.
