Ngenxa yokuguqulwa kwezinto ezithile, ikhwalithi ye-slidege eyenziwe yasebenza iba ukukhanya, ukuqina, futhi ukusebenza okulungisayo kuwohloka, inani le-SVI liyaqhubeka likhuphuka, futhi ukwahlukana kwamanzi okujwayelekile kodaka akunakwenziwa ethangini lediphoyi lesibili. Izinga le-sludge lethangi le-sedimentation sesendi liyaqhubeka likhuphuka, futhi ekugcineni i-sludge ilahlekile, futhi ukugxila kwe-MLSS ethatini le-aeration kuncishiswe ngokweqile, ngaleyo ndlela kubhubhise i-sludge ekusebenzeni okujwayelekile kwenqubo. Le nto ibizwa ngokuthi yi-sludge bulking. I-Sludge Bulking iyinto evamile engajwayelekile ehlelweni olusebenzayo lwe-Sludge Procept System.
Inqubo esetshenzisiwe ye-sludge manje isetshenziswa kabanzi ukwelashwa kwamanzi amdaka. Le ndlela ithole imiphumela emihle ekwelapheni izinhlobo eziningi zamanzi amdaka e-organic anjengendle yendle, ukwenziwa kwamaphepha nokudaya amanzi adoya amanzi, amanzi adoti kanye namanzi amdaka amakhemikhali kanye namanzi amdaka amakhemikhali kanye namanzi amdaka. Kodwa-ke, kunenkinga ejwayelekile ekwelashweni okucushiwe kwe-sludge, okungukuthi, i-sludge kulula ukugcwala ngesikhathi sokusebenza. I-Sludge Bulking ihlukaniswe ngokuyinhloko ibe ngama-bacterio ahlekisayo ngohlobo lwe-sludge bulking kanye namagciwane angenawo okulimele anohlobo lwama-bacteria alolonga ama-sludge bulking, futhi kunezizathu eziningi zokwakheka kwazo. Ukulimala kwe-sludge bulking kubi kakhulu, uma kwenzeka, kunzima ukulawula, nesikhathi sokutakula sinde. Uma izindlela zokulawula zingathathwanga ngesikhathi, ukulahleka kwe-sludge kungenzeka, kulimaze ngokuyisisekelo ukusebenza kwethangi le-aoration, okuholela ekuweni kwalo lonke uhlelo lokwelashwa.
Ukungezwa kwe-calcium chloride kungavimba ukukhula kwamagciwane okulila, okulungele ukwakheka kwe-bacteri minelles, futhi kuthuthukise ukusebenza kokuxazulula i-sludge. I-calcium chloride izobola futhi ikhiqize i-chloride ion ngemuva kokuncibilika emanzini. I-Chloride ion inokuhlanza inzalo kanye nokutholwa kwamagciwane emanzini, okungabulala ingxenye yamagciwane okulindisa futhi kuvinjelwe ukuvuvukala kwe-sludge okubangelwa amagciwane okulila. Ngemuva kokumisa ukungezwa kwe-chlorine, i-chloride ion nayo ingahlala emanzini isikhathi eside, futhi amagciwane okulila awakhuli ngokweqile esikhathini esifushane, futhi ama-microorganisms angenza ukuthi ukufakwa kwe-calcium chloride kungavimba ukukhula kwamagciwane okulila futhi kunomthelela omuhle ekuxazululeni ukuvuvukala kwe-sludge.
Ukungezwa kwe-calcium chloride kungalawula ukuvuvukala kwe-sludge ngokushesha nangendlela efanele, futhi i-svi ye-sludge esetshenzisiwe ingancishiswa ngokushesha. I-SVI yehle kusuka ku-309.5ml / g kuya ku-67.1ml / g ngemuva kokungeza i-calcium chloride. Ngaphandle kokungeza i-calcium chloride, i-sdiyo ye-sludge eyenziwe yasebenza nayo ingancishiswa ngokushintsha imodi yokusebenza, kepha izinga lokuncipha lihamba kancane. Ukungezwa kwe-calcium chloride akunamphumela osobala kumanani okususa i-COD, kanye nesilinganiso sokususa i-Cod sokungezwa i-calcium chloride kuphansi okungu-2% okuphansi kunalokho hhayi ukwengeza i-calcium chloride.
