摘要：

To　establish　an　fuzzy　control　system　of　denitrifying　phosphorus　removal　via　nitrite,　a　sequencing　batch　reactor　(SBR)　with　on-line　monitors　of　pH　was　applied　to　wastewater　treatment.　The　results　indicated　that　denitrifying　phosphorus　removal　via　nitrite　could　be　achived　and　inhibition　of　nitrite　on　phosphorus　uptake　could　be　avoid　by　step-feeding　nitrite.　During　denitrification　process　pH　increased　with　the　decrease　of　nitrite,　and　the　increase　of　pH　was　stopped　after　complete　consumption　of　nitrite.　So,　an　fuzzy　control　of　denitrifying　phosphorus　removal　via　nitrite　was　established　using　pH　as　fuzzy　control　parameter.　Further　more,　a　novel　two-sludge　denitrifying　phosphorus　removal　process　was　developed　using　above　fuzzy　control　strategy.　©　2012　Springer-Verlag　Berlin　Heidelberg.
