kukwira anaerobic sludge bed reactor (UASB)
UASB ndeimwe yeanokurumidza kukura ekugaya, ayo anoonekwa nekudzika-kumusoro kuyerera kwetsvina kuburikidza neakawedzera granular sludge bed. Iyo digester yakakamurwa kuita matunhu matatu, anoti sludge bed, sludge layer uye matatu-phase separator. Separadzanisa inotsemura gasi uye inodzivirira izvo zvakaomarara kuti zvirege kuyangarara uye kuburitsa kunze, kuitira kuti MRT iwedzerwe zvakanyanya kana ichienzaniswa neHRT, uye kugadzirwa kwemethane kwakagadziriswa zvakanyanya. Iyo sludge mubhedha nzvimbo inongoverenga 30% yeiyo digester vhoriyamu paavhareji, asi 80 ~ 90% yeiyo organic chinhu yakashatiswa pano.
Iyo nhanho-nhanhatu yekuparadzanisa ndiyo yakakosha michina yeUASB anaerobic digester. Iwo makuru mashandiro ayo gasi-emvura kupatsanurwa, yakasimba-mvura yekuparadzanisa uye sludge reflux, asi iwo ese anoumbwa negasi chisimbiso, sedimentation zone uye Reflux mubatanidzwa.
Maitiro ekuita
① Iyo digester ine yakapusa dhizaini uye isina kusanganisa mudziyo uye filler (kunze kweatatu-chikamu separator).
② Yakareba SRT uye MRT inoita kuti ibudirire yakakwira mutoro chiyero.
Kuumbwa kweiyo granular sludge kunoita kuti iyo microorganism isakwanise zvakasununguka uye inowedzera kudzikama kwemaitiro.
④ Izvo SS zvemukati zvemvura yakaderera.
Maitiro ekukanganisa
①. nhanho nhatu separator ichaiswa.
② Mugoveri wemvura anoshanda anodiwa kuti chikafu chigoverwe zvakaenzana.
③ Zvinyorwa zveSS zvinofanirwa kunge zvakadzikira.
④ Kana iwo hydraulic mutoro wakakwira kana SS mutoro wakakwira, zviri nyore kurasikirwa nemarara uye zvidiki.
⑤ Yakakwira hunyanzvi zvinodiwa kuti ishandiswe.
