Thepa e Ncha ea Phekolo ea Likhoerekhoere tsa Mahaeng
Litšobotsi tsa likhoerekhoere tsa mahaeng li kenyelletsa metsi a phehang ka kichineng, ho hlapa, metsi a ho hlatsoa, le metsi a hlatsuoang a ntloana.Mehloli ena ea metsi e qhalakane ’me ha ho na libaka tsa pokello libakeng tsa mahaeng.Ka khoholeho ea metsi a pula, a phallela metsing a holim'a metsi, metsi a mobu, le libaka tsa metsi a ka tlas'a lefatše tse kang linōka, matša, liforo, matamo le matamo.Likahare tse phahameng tsa lintho tse phelang ke tšobotsi e ka sehloohong.
E hloka hore matšoao ohle a likhoerekhoere ka mor'a phekolo a kopane le "Comprehensive Wastewater Discharge Standard" GB8978-1996;Litekanyetso tsa boemo ba pele bakeng sa.Kamora hore lisebelisoa li sebelisoe, li ka fokotsa phallo ea likhoerekhoere, tsa fokotsa ts'ilafalo ea tikoloho ka nepo, le ho sebelisa mehloli ea metsi ka botlalo ho fihlela ts'ebetso ea lefela.
Melao-motheo ea moralo oa lisebelisoa tse ncha tsa ho hloekisa likhoerekhoere malapeng:
1. Ho kenya tšebetsong maano a mantlha a naha mabapi le tshireletso ya tikoloho, le ho kenya tshebetsong maano, melawana, melawana le maemo a amehang a naha le a lehae;
2. Ka lebaka la hore metsi a litšila a finyella litlhoko tsa phekolo, boiteko bo lokela ho etsoa ho boloka matsete le ho sebelisa melemo ea sechaba, moruo, le tikoloho ea merero ea ho hloekisa likhoerekhoere;
3. Khetha mokhoa oa ho sebetsa o tenyetsehang, o bonolo ho o sebetsa le ho o laola, 'me o na le mesebetsi e tsitsitseng le e ka tšeptjoang;
4. Ka moralo, leka ho arola ho ea ka mesebetsi 'me u hahamalle ho ba le compactness ha u ntse u etsa bonnete ba hore ts'ebetso e sebetsa hantle.
5. Leka ho nahana ka boiketsetso bo sebetsang moralong oa ho fokotsa matla a basebetsi;
6. Nahana ka mehato e kang ho monyela ha letsoalo, ho fokotsa lerata, le ho ntša monko ho tšehetsa tsamaiso ea likhoerekhoere ho felisa tšilafalo ea bobeli tikolohong.
Melao-motheo ea ho khetha mokhoa oa ho hloekisa lisebelisoa tsa likhoerekhoere malapeng libakeng tse ncha tsa mahaeng:
Ho na le litšila tse ngata tsa manyolo ka har'a likhoerekhoere tsa malapeng, tse nang le CODcr e phahameng le BOD5, le BOD5 / CODcr boleng bo boholo ho feta 0.4, e bontšang ts'ebetso e ntle ea lik'hemik'hale.Ho eletsoa ho sebelisa mokhoa o thehiloeng ho biochemical bakeng sa kalafo.Ka lebaka la bongata ba metsi a litšila, lisebelisoa tsa ho hloekisa likhoerekhoere tse patiloeng li lokela ho sebelisoa bakeng sa phekolo ea lik'hemik'hale.Pele o kena ka sesebelisoa sa biochemical, leka ho tlosa litšila tse phaphametseng le tse kholo tse emisitsoeng ho tsoa ho likhoerekhoere tsa malapeng nakong ea sethaleng sa pele ho phekolo ka hohle kamoo ho ka khonehang, ebe u kenya tanka e laolang likhoerekhoere ho thibela liphello tse mpe ho pompo ea ho phahamisa likhoerekhoere.
Metsi a litšila a lapeng a hloekisoa ka tanka ea septic.Metsi a litšila a ho hlapa a tsoakoa le likhoerekhoere tse ling ka mor'a hore a hloekisoe ke motho ea bokellang moriri ebe a kena ka tankeng ea septic.Ka mor'a hore e phahamisoe ke pompo, e phalla ka har'a marang-rang ebe e kena ka tanka e laolang likhoerekhoere ka mor'a ho tlosa litšila tse khōlō tse emisitsoeng.Likhoerekhoere tse ka tankeng e laolang li phahamisoa ke pompo ea ho phahamisa 'me li kena ka har'a lisebelisoa tse kopantsoeng tsa ho hloekisa likhoerekhoere.The likhoerekhoere ka thepa e tšoaroa ke hydrolysis acidification, biological contact oxidation, sedimentation le mekhoa e meng, ebe e kena sefa, Ka mor'a ho sefa le ho thibela likokoana-hloko, metsi a litšila a kopana le litekanyetso 'me a lokolloa bakeng sa ho tala.Seretse sa ho lokisa se hlahisoang ke tanka ea sedimentation ka har'a thepa e kopantsoeng e isoa tanka ea seretse ka thepa e kopantsoeng ka ho hlobolisa moea.Seretse se tšeloa, se lokisoe, 'me se chekoa ka tanka ea seretse, 'me matla a phahametseng a khutlisetsoa tanka e laolang hore e hlatsoe bocha hammoho le metsi a litšila a pele.Seretse se teteaneng se pompeloa khafetsa le ho tsamaisoa ka teraka ea moiteli (hoo e ka bang hang ka mor'a likhoeli tse ling le tse ling tse tšeletseng).
Tlhahlobo ea ts'ebetso ea lisebelisoa tsa ho hloekisa likhoerekhoere malapeng libakeng tse ncha tsa mahaeng:

Grille e tsitsitse ebile e entsoe ka mesh ea tšepe e sa hloekang.Beha likarolo tse peli tse mahoashe le tse ntle ho tlosa likaroloana tse kholo tse emisitsoeng le litšila tse phaphametseng ka metsing.
② Tanka e laolang le pompo e phahamisang
Ka lebaka la ho feto-fetoha ho hoholo ha boleng le bongata ba likhoerekhoere, hoa hlokahala ho ba le matla a lekaneng a ho laola tanka bakeng sa ho tsitsisa boleng ba metsi le bongata bo kenang lisebelisoa tse kopaneng tsa likhoerekhoere.
Tanka e laolang e na le pompo ea likhoerekhoere e ka tlas'a metsi ho phahamisetsa metsi a litšila ho ea ho lisebelisoa tse kopaneng tsa likhoerekhoere.
③ Hydrolysis acidization tanka
Tanka ea hydrolysis acidification e na le li-filler tse kopantsoeng.Tlas'a ketso ea hydrolysis le acidification microorganisms ka tanka ena, metsi a litšila a hydrolyzed le acidified ka lintho tse nyenyane molek'hule ke macromolecular organic litšila, e leng thusa ho decomposition ea libaktheria aerobic ka tanka kopana le oxidation.
④ Phekolo ea lik'hemik'hale
Ho ipapisitsoe le boleng bo boletsoeng ka holimo ba likhoerekhoere, bongata, le litlhoko tsa ho lahla, ho kopantsoe le litšobotsi tsa likhoerekhoere.Sistimi ena ea biochemical e tla kopanya tanka ea oxidation, tanka ea sedimentation, tanka ea seretse, phaposi ea fene, tanka e ntšang likokoana-hloko le likarolo tse ling hore e be e le 'ngoe.Karolo e 'ngoe le e' ngoe e na le mesebetsi e lumellanang 'me e hokahane ho e' ngoe, 'me metsi a ho qetela a kopana le maemo.Tse latelang li hlalositsoe ka thoko:
Tlatsa tanka ea ho kopanya oxidation ka li-filler.Karolo e ka tlaase e na le aerator, 'me tsamaiso ea aeration e entsoe ka liphaephe tsa polasetiki tsa boenjiniere tsa ABS.Mohloli oa moea oa tsamaiso ea aeration o fanoa ke fan e hlophisitsoeng ka ho khetheha.
Karolo e ka holimo ea tanka ea sedimentation e na le lesela le feto-fetohang ho laola boemo ba metsi a tsoang;Karolo e ka tlase e na le sebaka sa conical sedimentation le sesebelisoa sa ho phahamisa moea oa seretse, se nang le mohloli oa moea o fanoeng ke fan.Seretse se isoa tanka ea seretse ka phahamiso ea moea.Nako ea ho boloka seretse ka tanka ea seretse ke matsatsi a ka bang 60.Seretse se hlahisoang ke sedimentation ea sistimi se tšeloa ka har'a tanka ea seretse ka ho phahamisoa ha moea, moo seretse se kopaneng, se lulang le ho bolokoa.Liphaephe tsa moea li behiloe ka tlase ho tanka ho thibela tšilo ea seretse ea anaerobic ho tloha ho hlahisa biogas, le ho oxidize sludge ho fokotsa kakaretso ea seretse;Leretse le teteaneng le pompeloa khafetsa le ho tsamaisoa ka literaka tsa moiteli.Karolo e ka holimo ea tanka ea seretse e na le sesebelisoa sa supernatant reflux ho tšela matla a holimo ho tanka ea acid hydrolysis.
