MBR Tekinoroji Inoshandura Kurapa Kwemvura Yakasviba neKushanda Kwepamusoro

MBR (Membrane Bio-Reactor) inzira inoshanda kwazvo yekuchenesa mvura yetsvina inosanganisa kurapwa kwechinyakare kwebiology (senge yakaitwa activated sludge method) ine membrane yekuparadzanisa tekinoroji. Mhedzisiro yaro ndeyekutsiva iyo yechinyakare yechipiri sedimentation tangi ine ultrafiltration kana microfiltration membrane (pore saizi 0.01 ~ 0.4 μm) kuti iwane slurry kupatsanurwa kwemvura uye kugadzirisa effluent mhando panguva imwe chete. MBR membrane tekinoroji inotanga yabvisa biodegradable organic zvinosvibisa mumvura kuburikidza neyakagadzirwa sludge, uye yobva yashandisa membrane modules kubata nechisimba sludge yakamiswa uye yakawanda yakamiswa yakasimba mubioreactor kuti iwane kusimba-mumvura kupatsanurwa kwemvura yakacheneswa uye yakagadziriswa sludge, nekudaro ichisimbisa efflugeent kurapwa uye kuvandudza hunhu hwekuita kwebiochemical.

Nzira yekurapa yeMBR yakave nemigumisiro inokosha pakurapa kweCOD mumvura yakasvibiswa yenitrogen fertilizer industry, uye mhirizhonga yebiochemical yakanga ine nhanho pfupi yehutano uye acclimation, uye mhedzisiro yacho yakagadzikana kubva pazuva rechitatu. Mune zvese zvakagadzikana danho rekurapa uye rakajairwa danho rekushanda, chiyero chekubvisa COD chinogona kuchengetedzwa, uye chiyero chekubvisa chinodarika 90%. Avhareji yekutumira kunze COD inodzorwa pasi pe30mg/L.

MBR musanganiswa unoshanda wemembrane separation tekinoroji uye nzira yekurapa yebhayoloji, uye kwainotangira ndeyekutsiva yechipiri sedimentation tangi mune yakashongedzwa sludge nzira ine membrane yekuparadzanisa tekinoroji yekuparadzaniswa kwakasimba-mvura. Ichi chiitiko hachingoite zvinobudirira chinangwa chekuparadzanisa slurry, asi zvakare chine mabhenefiti asingaenzaniswi echinyakare maitiro ekugadziriswa kwetsvina yepamusoro:

1. Kubudirira kwakasimba-kuparadzaniswa kwemvura, kupatsanurwa kuri nani zvikuru kupfuura kwetangi rekare, mvura yakasviba yakanaka, tsvina yakasimudzwa yakaoma uye turbidity iri pedyo ne zero, uye inogona kushandiswa zvakare zvakananga, ichiziva kushandiswa kwetsvina.

2. Kubata kwakanaka kwekuita kwe membrane kunoita kuti ma microorganisms anyatsobatwa mu bioreactor, anoona kupatsanurwa kwakakwana kwe reactor hydraulic retention time (HRT) uye sludge age (SRT), uye kutonga kwekushanda kunoshanduka uye kugadzikana.

3. Nekuti MBR inosanganisa aeration tangi uye yechipiri sedimentation tangi yechinyakare sewage yekuchenesa mune imwe, uye inotsiva ese maitiro ekurapwa kwepamusoro, inogona kuderedza zvakanyanya nzvimbo yepasi uye kuchengetedza civil engineering investment.

4. Inobatsira pakubata uye kubereka kwebhakitiriya ye nitrifying, uye hurongwa hune nitrification yepamusoro. Kuburikidza nekushandurwa kwemaitiro ekushanda, inogona zvakare kuve nebasa re deammonization uye phosphorus kubviswa.

5. Nemhaka yokuti nguva yematope inogona kuva yakareba kwazvo, kukanganisa kwehutano hwe refractory organic matter kunovandudzwa zvikuru.

6. Iyo reactor inoshanda pasi pepamusoro volumetric mutoro, yakaderera sludge mutoro uye yakareba sludge age, uye yakasara sludge kubuda yakaderera zvikuru.

7. Iyo sisitimu inoziva kutonga kwePLC, uye kushanda uye manejimendi zviri nyore
