  • Patent number: 8216471
    Abstract: An integrated bioreactor and its applications as well as a method for treatment of highly-concentrated organic wastewater using the same. The integrated bioreactor with a concentric columnar structure includes an inner layer and an outer layer, in which the inner layer is an upflow anaerobic sludge blanket (UASB) and the outer layer is a moving bed biofilm reactor (MBBR). The effluent of the MBBR is recycled into UASB via a reflux pump mounted between a water tank and the integrated bioreactor. A water outlet of the UASB is arranged with an on-line pH monitor and a mechanical agitation device is arranged on the top of a bottom water distributor. The bioreactor is low in cost, features friendly maintenance, stable operation, and high degree of automation, and can be applied under low temperature.
