Analysis　different　kinds　of　anaerobic　fermentation　technology　using　in　prevent　and　control　of　livestock　and　poultry.　Comparing　removal　rate　of　COD,　total　Nitrogen,　total　Phosphorus　of　Mixed　anaerobic　fermentation　technology　(CSTR),　upflow　sludge　bed　reactor　(USR)　and　simple　anaerobic　pool.　Removal　rate　of　CSTR　and　USR　is　obvious　better　than　simple　an　aerobic　pool,　and　removal　rate　is　proportional　to　the　pollutant　concentration.　Overall　evaluations　of　investment,　occupation　of　land　and　rate.　Points　out　the　problems　exist　in　the　using　of　anaerobic　fermentation　technology　and　put　forward　reasonable　suggestions.
