摘要： One embodiment of an apparatus and method for treating agricultural animal wastewater that costs less to build, is easy to operate, and requires little energy input. The method employs natural systems for wastewater treatment; an initial anaerobic digestion treatment followed by batch floating aquatic plant treatment. The batch floating aquatic plant treatment of effluent and subsequent batch discharge provides increased control of the treatment process. Opportunistic collection and use of biogas and floating aquatic biomass results in additional benefits. The apparatus reduces the cost and land area required for the system by subdividing a lagoon into an anaerobic digestion treatment zone below the apparatus and a floating aquatic plant treatment zone above the apparatus. In addition, the apparatus is disposed in the lagoon in such a way that it facilitates the collection of biogas evolving from anaerobic digestion treatment beneath the apparatus by diverting it to areas to be collected.
