Uyazi? Ngaphezu kukadoti odinga ukuhlungwa, i-leachate yezindawo zokulahla udoti nayo idinga ukuhlungwa.
Ngokwezici ze-leachate yokulahla udoti, ingahlukaniswa kalula kanje: i-leachate yokulahla udoti esiteshini sokudlulisa, i-leachate yemfucuza yasekhishini, i-leachate yokulahla udoti, kanye ne-leachate yokulahla udoti yezitshalo ezishiswayo.
Yiziphi izici zalezi zinhlobo ezine ze-leachate yokulahla udoti?
Izici zesiteshi sokudlulisa i-leachate:
1. Kunemithombo eminingi eyinhloko yamanzi angcolile: ikakhulukazi amanzi angcolile asekhaya, amanzi angcolile ahlanzwayo, kanye ne-leachate yokulahla udoti.
2. Ngenxa yesikhathi esifushane sokuhlala kukadoti esiteshini sokudlulisa udoti, umphumela wokukhipha udoti mncane.
3.Ukuhlushwa kokungcola esiteshini sokudlulisa kuphansi kunokwezinye izinto ezingcolisayo, kanti ukuhlushwa kwe-COD kungaba ngu-5000~30000mg/L..
Izici eziyinhloko ze-leachate yokulahla udoti yilezi:
①Kunezinhlobo eziningi zezinto eziphilayo ezingcolisa umoya, futhi ikhwalithi yamanzi iyinkimbinkimbi (iqukethe izinto eziningi eziphilayo)
②Ukuhlushwa okuphezulu kokungcola kanye noshintsho olubanzi (ukuhlushwa kokuqala kwe-BOD kanye ne-COD kuphakeme kakhulu, kufika emashumini ezinkulungwane zama-milligram ngelitha, inani le-pH lingaphansi noma lingaphansi kancane kuka-7, i-B/C iphakathi kuka-0.5-0.6, futhi izakhiwo ze-biochemical zinhle), ngokuvamile, isilinganiso se-COD, i-BOD, i-BOD/COD siyancipha “ngobudala” bendawo yokulahla udoti, futhi i-alkalinity iyanda.
③Ikhwalithi yamanzi kanye nobuningi kuyahlukahluka kakhulu: inani lamanzi liyahlukahluka kakhulu ngokwezinkathi zonyaka (isikhathi semvula ngokusobala sikhulu kunesikhathi sonyaka esomile); ukwakheka kanye nokugcwala kokungcola nakho kuyashintsha ngokwezinkathi zonyaka; ukwakheka kanye nokugcwala kokungcola kuyashintsha ngesikhathi sokulahla udoti.
Izici eziyinhloko ze-leachate yokulahla udoti ezitshalweni zokushiswa yilezi:
①Amazinga aphezulu e-COD, i-BOD, kanye ne-ammonia nitrogen (i-COD ingafinyelela ku-40,000 ~ 80,000)
②Isikhathi sokubilisa side kunesesiteshi sokudlulisa.
Izici eziyinhloko ze-leachate yemfucuza yasekhishini:
①Izinto eziqinile ezilenga kakhulu: Ama-leachat ahlukene anezilinganiso ezahlukene zezinto eziqinile ezilengayo esimweni esingaxazululeka kanye nesimo se-colloidal, esiphezulu kusukela ku-60,000 kuya ku-120,000 mg/L, ngokusabalala okuphezulu futhi kunzima ukuwahlukanisa;
②Okuqukethwe kwamafutha amaningi: ikakhulukazi amafutha ezilwane nemifino, afinyelela ku-3000mg/L ngemva kokwelashwa kwangaphambilini
③I-COD ephezulu, ngokuvamile kulula ukuyibola, ifinyelela ku-40,000 kuya ku-150,000 mg/L;
④i-pH ephansi (ngokuvamile cishe i-3);⑤okuqukethwe usawoti omningi.
