Research Abstract

The discharge of livestock wastewater that contains high concentration of nitrogen causes eutrophication, algal blooms and groundwater pollution. We developed a membrane-aerated biofilm reactor (MABR) capable of simultaneous nitrification and denitrificaiton (SND) in a single reactor.
1.Analysis of dissolved oxygen (DO) profile in biofilms
DO profile in biofilms of several thicknesses was investigated using an oxygen microelectrode. From this experiment, a large anaerobic zone was observed at the bottom of the thick biofilm. This result clearly indicated the possibility that quite different microenvironment is created in a same biofilm, allowing for SND.
2.Feasibility of SND using the MABR
Feasibility of SND on the MABR for treatment of domestic wastewater was conducted for 150 days. After 50 day, removal efficiencies of organic carbon and nitrogen were more than 90%, which indicates that SND can be accomplished using the MABR.
3.Application of the MABR to livestock wastewater
The removal characteristics from livestock wastewater were investigated for 1 year. Average removal efficiencies of organic carbon and nitrogen were 96% and 83% at removal rates of 5.76 g-C/(m^2・day) and 4.48 g-N/(m^2・day), respectively. The combination of the in situ detection of specific bacteria and determination of the DO microprofiles made it possible to prove the mechanism of SND and the microbial ecology in the biofilm. Furthermore, nitrogen removal not via nitrate but nitrite was mainly achieved in the MABR system. The MABR takes advantage of the easy control of oxygen mass transfer, and thus it is useful when removing nitrogen from low carbon/nitrogen-ratio wastewater such as livestock.
