Ingabe uyazi?Ngaphezu kukadoti odinga ukuhlungwa, i-leachate yokulahla imfucumfucu nayo idinga ukuhlungwa.
Ngokwezimpawu ze-leachate yokulahla imfucumfucu, ingahlukaniswa kalula ibe: i-leachate yokulahla isizinda sokudlulisa, i-leachate yasekhishini, i-leachate yendawo yokulahla imfucumfucu, kanye ne-leachate yendawo yokushiswa kwezitshalo.
Yiziphi izici zalezi zinhlobo ezine ze-leachate yokulahla imfucumfucu?
Izici zesiteshi sokudlulisa ziyaphuma:
1. Miningi imithombo yamanzi angcolile: ikakhulukazi amanzi angcolile asekhaya, amanzi angcolile akhishwayo, kanye ne-leachate yokulahla imfucumfucu.
2. Ngenxa yesikhathi esifushane sokuhlala sikadoti esiteshini sokudlulisa udoti, ukukhishwa kwe-leachate kuncane.
3.Ukugcwala kokungcola esiteshini sokudlulisa kuphansi kunezinye izinto ezingcolisayo, futhi ukugcwala kwe-COD cishe ku-5000 ~ 30000mg/L.
Izici eziyinhloko ze-leachate yokulahla imfucumfucu yilezi:
①Kunezinhlobo eziningi zokungcola kwemvelo, futhi ikhwalithi yamanzi iyinkimbinkimbi (iqukethe inqwaba yezinto eziphilayo)
②Ukugcwala okuphezulu kokungcola kanye noshintsho olubanzi olubanzi (ukugxila kwe-BOD yokuqala kanye ne-COD kuphezulu kakhulu, kufika emashumini ezinkulungwane zamamiligremu ilitha, inani le-pH lingaphansi noma lingaphansi kuka-7, B/C liphakathi kuka-0.5-0.6, kanti izakhiwo ze-biochemical zinhle) , ngokuvamile, isilinganiso se-COD, BOD, BOD/COD siyehla “ngeminyaka” yendawo yokulahla imfucumfucu, futhi i-alkalinity iyanda.
③Izinga lamanzi nenani liyahluka kakhulu: inani lamanzi liyahlukahluka kakhulu ngokwezikhathi zonyaka (inkathi yemvula ngokusobala inkulu kunenkathi eyomile);ukwakheka nokugcwala kwezinto ezingcolisayo nakho kuyashintsha nezinkathi zonyaka;ukwakheka nokugcwala kokungcola kuyashintsha ngesikhathi sokulahlwa kwemfucuza.
Izici eziyinhloko ze-leachate ye-landfill ezitshalweni zokushiswa yilezi:
①Ukugxila okuphezulu kwe-COD, BOD, ne-ammonia nitrogen (i-COD ingafinyelela ku-40,000~80,000)
②Isikhathi sokuvutshelwa side kunaleso sesiteshi sokudlulisa.
Izici eziyinhloko ze-kitchen waste leachate:
①Okuqinile okumisiwe okuphezulu: Ama-leachate ahlukene anezilinganiso ezihlukene zezinto eziqinile ezimisiwe esimweni sokuzinza kanye ne-colloidal state, efinyelela ku-60,000 kuya ku-120,000 mg/L, enokusabalalisa okuphezulu futhi okunzima ukuhlukana nayo;
②Okuqukethwe okuphezulu kwamafutha: ikakhulukazi amafutha ezilwane nemifino, afika ku-3000mg/L ngemva kokwelashwa kwangaphambili
③I-COD ephezulu, ngokuvamile kulula ukwehlisa i-biodegrade, kufika ku-40,000 kuya ku-150,000 mg/L;
④i-pH ephansi (imvamisa cishe i-3);⑤usawoti omningi.
Siyakwamukela ukuxhumana nemikhiqizo yethu—-AMAKHEMIKHALI OMHLANZI
