摘要：

This　study　used　an　intermittent　self-agitation　anaerobic　baffled　reactor　(SA-ABR)　to　treat　food　waste.　The　organic　matter　and　detailed　composition　evolution　were　analyzed　under　continuous　operation.　The　gas　production　rate　was　2.43　±　0.18　L-Gas/d/L-Re,　and　the　biogas　conversion　was　0.94　L-Gas/g-TS.　The　effluent　concentration　of　total　chemical　oxygen　demand　(COD)　was　22.5　±　2.44　g/L,　and　the　removal　rate　of　soluble　COD　was　always　over　97%.　In　this　study,　the　removal　rates　of　carbohydrate,　protein,　and　lipids　in　the　SA-ABR　treatment　were　95%,　60%,　and　85%,　respectively,　and　the　concentrations　were　0.11　g/L,　0.32　g/L,　and　0.33　g/L,　respectively.　The　conversion　of　soluble　organic　matter　was　much　higher　than　that　of　insoluble　substrates.　The　concentration　of　soluble　pollutants　was　significantly　lower　than　that　of　pollutants　in　suspended　matter.　The　treatment　of　organic　matter　in　the　first　half　of　the　SA-ABR　was　85–100%　that　of　the　entire　reactor.　©　2020　Elsevier　Ltd
