Study on the technology to treat the sewage in a paddock using a reed bed
2001 - 2001
When the excrement is accumulated to a certain amount, it is in many cases removed by a shovel, but in the meantime the components of the excrement run out by rainwater. Since the density of the sewage in the paddock is lower than slurry, it is technically difficult to treat the sewage. An activated sludge method is known as a treatment method for sewage with low density, but it is very difficult to adopt this method for individual management for economical reason. On the other hand the purification ability of water plants in marshes is widely known and they are used as a reed bed in Scotland or Ireland. This system is a method to purify household wastewater or industrial wastewater by natural marshes, but it is expected to be applied for the sewage with low density of livestock excrement. In other words an individual management provides an artificial pond with plants into which the sewage in the paddock is flowed to make a small reed bed to purify the sewage. The present test seeks the possibility to purify the sewage in the paddock using a mock reed bed.
