摘要：

The　effluent　of　an　Anaerobic/Oxic(A/O)　process　removing　phosphorous　from　municipal　wastewater　was　used　as　influent　to　a　partial　nitritation　process　of　pilot　scale　plug　flow　reactor　(volume　of　1.14　m3)　with　the　conditions　of　room　temperature　(16.4-25.5°C)　and　limited　oxygen　(DO　concentration　of　0-0.60　mg/L).　The　experimental　result　indicates　that　relatively　low　DO　concentration　(2--N)/m(NH4+-N)　averaged　1.11,　the　effect　of　partial　nitritation　is　stable　for　the　nitrite　accumulation　rate　is　over　95%;　which　meet　the　requirement　of　the　appropriate　influent　for　the　subsequent　ANAMMOX　biofilter.　During　the　whole　operating　period,　the　settleability　of　sludge　is　good　with　volume　Index　(SVI)　being　60-100　mL/g,　and　sludge　bulking　does　not　appear.
