Phosphorus　recovery　and　carbon　reuse　from　municipal　sludge　have　been　regarded　as　an　effective　method　of　recycling　wastes.　In　this　study,　an　innovative　proportional　acidification　method　was　developed　to　release　phosphate　from　municipal　sludge　and　acquire　struvite,　short-chain　fatty　acids　(SCFAs),　and　acidulated　biological　activated　carbon　(ABAC)　as　three　cleaner　products.　Acidulated　treatment　could　adequately　release　phosphate　from　municipal　sludge.　Over　95%　of　total　phosphorus　was　extracted　at　pH　2.0,　and　98.9%　of　soluble　phosphate　was　recovered　by　activated　brucite　ultra-fine　powder　(ABP)　as　struvite　crystal　within　30　min　at　pH　7.0-7.5.　The　optimal　volumetric　ratio　of　acidulated　sludge　mixture　and　unacidified　supernatant　was　4:6　after　fermentation　process,　while　45.4%　of　strong　acid　was　saved　compared　to　sludge　complete　acidification.　The　field　emission　scanning　electron　microscopy　(FE-SEM)　and　X-ray　diffraction　(XRD)　revealed　that　struvite　crystallization　was　a　process　of　magnesium　ions　dissolved　and　reconstruction.　381.1　mg　of　phosphate　and　159.3　mg　of　ammonium　could　crystallize　with　adding　1　g　ABP.　Acetate　and　propionate　occupied　74.2%-82.3%　of　total　SCFAs　at　neutral　fermentation　condition,　and　one　kilogram　dry　sludge　could　recover　0.079　kg　acetate　and　0.023　kg　propionate.　Moreover,　the　FE-SEM　micrographs　and　Brunauer-Emmett-Teller　(BET)　analysis　indicated　that　ABAC　had　better　physical　properties　than　conventional　biological　activated　carbon　(BAC).　The　recovery　process　of　all　three　products　avoided　creating　new　pollutants,　and　scheme　economic　assessment　showed　roughly　balance　of　chemical　cost　and　products　return.　This　integrated　scheme　can　promote　sustainable　recovery　nutrients　from　municipal　sludge　in　the　form　of　large-scale　applications.
