摘要：

In　order　to　improve　the　efficiency　of　biological　nitrogen　removal,　a　two-compartment　SBBR　operated　with　alternate　aeration　and　fill　was　proposed.　A　traditional　SBBR　was　divided　into　two　identical　compartments　by　a　piece　of　vertical　clapboard,　and　was　filled　by　ceramic　particles　for　biofilm　growth.　The　reactor　was　operated:　fill　from　the　left　inlet,　aeration　by　the　right　aerator,　draw,　fill　from　the　right　inlet,　aeration　by　the　left　aerator,　draw.　Alternate　operation　created　one　compartment　with　high　DO　and　the　other　with　low　DO　and　stored　carbon　to　improve　nitrification　and　denitrification,　respectively.　TN　removal　rate　could　reach　up　to　approximately　89.2%.　The　effect　of　aeration　rate　on　effluent　TN　concentration　and　TN　volumetric　load　was　tested　and　analyzed.　Aeration　rate　ranged　from　0.2m3/h　to　0.6m3/h　in　the　aeration　compartment　was　recommended.　©　2011　IEEE.
