    • A controlled eutrophication system and process are disclosed. The system includes the combination of a partitioned aquaculture system in conjunction with an anaerobic digester. Wastewater containing pollutants, such as nitrogen and phosphorus, are fed to the partitioned aquaculture system. Algae within the system converts the pollutants into algal biomass. Fish populations, in turn, control the algal populations. The fish populations may then be periodically harvested for human or animal consumption. A polishing chamber is contained in the system in which aquatic organisms remove substantial amounts of the algae from batch fed additions of water. The water is then discharged to an external water source containing virtually no pollutants. In one embodiment, the biomass excreted by the aquatic organisms in the system are collected and fed to a digester. In the digester, the biomass is converted to a hydrocarbon gas and collected for its fuel value, while the liquid fraction is collected for its fertilizer value.
    • 公开了一种受控的富营养化系统和方法。 该系统包括分离的水产养殖系统与厌氧消化器的组合。 含有污染物(如氮,磷)的废水进入分区水产养殖系统。 系统内的藻类将污染物转化为藻类生物质。 反过来,鱼类种群也可以控制藻类种群。 然后可以定期收获鱼种以供人或动物消费。 抛光室包含在系统中,水生生物从批量加入的水中除去大量的藻类。 然后将水排放到几乎不含污染物的外部水源。 在一个实施方案中,由系统中的水生生物排泄的生物质被收集并进料到消化器。 在蒸煮器中,将生物质转化为烃类气体并收集其燃料值,同时收集液体馏分用于其肥料值。
