Anaerobic　ammonium　oxidation　(anammox)　technology　has　become　one　of　the　most　innovative　and　efficient　researches　in　the　field　of　wastewater　deammonification　due　to　its　advantages　such　as　no　need　to　add　carbon　sources,　energy　saving　and　low　sludge　yield.　Researchers　have　carried　out　a　lot　of　research　on　reaction　mechanism,　microbial　community,　application　form　Compared　to　the　the　split　anammox　process,　the　layou　of　integrated　process　is　more　compact,　which　significantly　reduces　the　cost　of　infrastructure　and　operation.　In　this　paper,　the　advatages　of　integrated　anammox　technology　were　summarized　from　the　point　of　engineering　application.　Combined　with　the　engineering　cases　of　integrated　anammox　process　in　municipal　wastewater　at　home　and　abroad,　the　research　progress　of　anammox　microorganisms　in　integrated　process　system　was　reviewed　from　the　aspects　of　granular　sludge,　biofilm,　suspended　sludge　system　and　the　nutrition　type　of　main　functional　bacteria.　The　process　performance,　application　and　influence　factors　of　different　integrated　process　were　also　discussed.　The　application　bottleneck　and　development　direction　of　the　integrated　process　in　urban　sewage　treatment　were　discussed　in　order　to　provide　reference　for　engineering　application　of　the　integrated　anammox　process.　©　2022,　Science　Press.　All　right　reserved.
