Kodi mumadziwa?Kuphatikiza pa zinyalala zomwe zimafunikira kusanjidwa, zotayiramo zimayeneranso kusanjidwa.
Malingana ndi makhalidwe a leachate ya kutayirako, ikhoza kugawidwa m'magulu awiri: malo otayiramo zinyalala, leachate ya zinyalala za m'khitchini, zotayiramo zinyalala, ndi zotayiramo zotayirako nyansi.
Kodi mitundu inayi ya zotayiramo zotayiramo zinyalala ili ndi makhalidwe ati?
Makhalidwe a transfer station leachate:
1. Pali magwero ambiri a madzi oipa: makamaka madzi oipa a m'nyumba, otaya madzi oipa, ndi zotayira zotayiramo nthaka.
2. Chifukwa cha nthawi yochepa yokhalamo zinyalala m'malo osungirako zinyalala, kutulutsa kwa leachate ndi kochepa.
3.Kuchuluka kwa zoipitsa pamalo otumizirako ndikotsika kuposa zoipitsa zina, ndipo kuchuluka kwa COD ndi pafupifupi 5000 ~ 30000mg/L..
Makhalidwe akuluakulu a leachate yamatope ndi awa:
①Pali mitundu yambiri ya zowononga zachilengedwe, ndipo mtundu wamadzi ndi wovuta (muli ndi zinthu zambirimbiri)
②Kuchuluka kwa zowononga zowononga komanso kusintha kosiyanasiyana (kuchulukira kwa BOD ndi COD ndikokwera kwambiri, mpaka makumi masauzande a ma milligrams pa lita imodzi, pH mtengo uli kapena kutsika pang'ono kuposa 7, B/C uli pakati pa 0.5-0.6, ndipo biochemical properties ndi zabwino) , nthawi zambiri, chiŵerengero cha COD, BOD, BOD / COD chimachepa ndi "zaka" za kutayirako, ndipo alkalinity imawonjezeka.
③Mkhalidwe wa madzi ndi kuchuluka kwake zimasiyana kwambiri: kuchuluka kwa madzi kumasiyana kwambiri ndi nyengo (nyengo yamvula ndi yokulirapo kuposa nyengo yachilimwe);kupangidwa ndi kuchuluka kwa zoipitsa kumasinthanso ndi nyengo;kapangidwe ndi kuchuluka kwa zowononga zimasintha ndi nthawi yotayira.
Makhalidwe akuluakulu a leachate m'mafakitale otenthedwa ndi:
①Kuchuluka kwa COD, BOD, ndi ammonia nitrogen (COD imatha kufika 40,000~80,000)
②Nthawi yowotchera ndi yotalikirapo kuposa ya malo osinthira.
Zofunikira zazikulu za leachate yakukhitchini:
①Zomwe zimayimitsidwa kwambiri: Mitundu yosiyanasiyana ya leachates ili ndi magawo osiyanasiyana a zolimba zoyimitsidwa mu settleable state ndi colloidal state, mpaka 60,000 mpaka 120,000 mg / L, ndi kufalikira kwakukulu komanso kovuta kupatukana;
②Mafuta ochuluka: makamaka mafuta a nyama ndi masamba, mpaka 3000mg/L atatha kuchiritsa
③COD yapamwamba, yomwe nthawi zambiri imakhala yosavuta kuisintha, mpaka 40,000 mpaka 150,000 mg/L;
④pH yochepa (nthawi zambiri pafupifupi 3);⑤mchere wambiri.
