Ndi chitukuko cha chuma, madzi kuipitsa kukukulirakulirakulira, boma lawonjezeka pang'onopang'ono kukula kwa m'tawuni zimbudzi mankhwala, makamaka m'zaka zaposachedwapa, lonse za ndalama zake akupitiriza kukula, ndi liwiro kumanga zimbudzi mankhwala zomera yapita patsogolo kwambiri. Anthu ambiri ali ndi chidwi, chiyani ndi njira yochotsera zinyalala? Fotokozani momveka bwino m'nkhani. Kumvetsetsa mfundo ya kuchimbudzi
Pali njira ziwiri zokha zoyeretsera zimbudzi: imodzi ndiyo kupatukana, ndi chinacho ndi kutembenuka.Mvetserani mfundo yoyendetsera zimbudzi
Kupatukana ndiko kulekanitsa zoipitsa zina m’zimbudzi ndi madzi thupi, miyeso yeniyeni imaphatikizapo mvula, flocculation, centrifugation, kuyandama mpweya, kuwomba ndi zina zotero, zofunika thupi ndi mankhwala njira. Nthawi zambiri, zoipitsa mu zimbudzi monga organic kanthu akhoza kuchotsedwa pambuyo kulekana koyambirira ndi chithandizo, ndipo zofunikira ndizo osati apamwamba, kotero akhoza kutulutsidwa mwachindunji. Izi zimatchedwa primary processing.
Zowononga zina sizingathe kulekanitsidwa bwino, monga kusungunuka organic kanthu, ammonia nayitrogeni, phosphates, amene ayenera kusinthidwa kukhala zinthu zopanda vuto, kapena zinthu zolekanitsidwa mosavuta. Chofunika kwambiri Njira yazachilengedwe muzachimbudzi ndi ntchito yosinthira mwachitsanzo, kusungunuka organic kanthu amachotsedwa ndi kusintha organic kanthu kukhala carbon dioxide (yomwe nthawi zambiri imakhala yopanda vuto komanso yolekanitsidwa mosavuta ndi madzi) ndi matope achilengedwe (ovulaza, komanso amagwa mosavuta komanso olekanitsidwa). Izi amatchedwa secondary processing. Pali njira zambiri zosinthira, monga zosiyanasiyana zapamwamba makutidwe ndi okosijeni, acid-base neutralization ndi zina zotero. The cyanide zimbudzi opangidwa ndi Tianjin ngozi kuphulika akhoza wosweka ndi oxidation wamphamvu wa hydrogen peroxide kuti aswe chomangira cha C-N ndikuchipanga zopanda vuto.
Njira yopangira zimbudzi zapakhomo nthawi zambiri imakhala 1 grid 2 primary mpweya 3 biochemical mankhwala 4 yachiwiri mpweya 5 disinfection. Kuchokera pagulu lomwe lili pamwambapa, 124 ndi kulekana ndipo 35 ndikusintha. Izi njira yosiyana, ngakhale yokhazikika komanso yosavuta, koma imakhala ndi dera lalikulu, ndalama zomanga, nthawi yokhalamo yayitali (imatha kumveka ngati yayikulu kuchuluka kwa zomanga kumatenga gawo lalikulu).
Tsopano matekinoloje atsopano akukonda kwambiri kuphatikiza kupatukana ndi kusinthidwa kukhala gulu la machitidwe kuti achepetse ndalama ndikuwongolera bwino, monga membrane biological treatment process (MBR), yomwe ndi biochemical ndondomeko ndi pulayimale ndi sekondale sedimentation mu dziwe, kotero mwachionekere ndi mapazi akuchepa kwambiri. Ngakhale mtengo wa nembanemba ndondomeko ndi akadali apamwamba, ndi kupita patsogolo kwaukadaulo, mtengo udzakhala wotsika komanso pansi, ndipo idzakhala yotchuka kwambiri.
