<p>In a water processing system for processing highly contaminated water, comprising an anaerobic chamber, an aerobic chamber, a buffering chamber, and a recycle for recycling part of the water received in the buffering chamber back to the anaerobic chamber, filter material forms a buoyant filter layer in an upper part of the water received in the anaerobic chamber without any constraint imposed on the filter material with the result that the filter layer can be highly resistant against clogging, and can be easily maintained with the result that the overall system can be made both simple and economical. Either an upflow arrangement or a downflow arrangement is possible for the anaerobic chamber. Furthermore, by using an integral structure combining various processing units into a single processing vessel, the overall size of the system can be minimized. Additionally, because nitrifying microbes and denitrifying microbes can be maintained at high concentrations in the processing chambers, a high purification performance can be attained while minimizing the size of the processing vessel. The buffering chamber may server as a reservoir for a recycle pump.</p> |
