Zokhudza Malo Otayira Zinyalala

Kodi mukudziwa? Kuwonjezera pa zinyalala zomwe ziyenera kukonzedwa, zinyalala zomwe zimatayidwa m'malo otayira zinyalala ziyeneranso kukonzedwa.

Malinga ndi makhalidwe a leachate yotayira zinyalala, imatha kugawidwa m'magulu awa: leachate yotayira zinyalala pamalo osinthira, leachate yotayira zinyalala kukhitchini, leachate yotayira zinyalala ku malo otayira zinyalala, ndi leachate yotayira zinyalala ku malo otenthera zinyalala.

Kodi mitundu inayi ya zinyalala zotayira zinyalala ndi yotani?

Makhalidwe a malo osinthira otayira:

1. Pali magwero ambiri akuluakulu a madzi otayira: makamaka madzi otayira apakhomo, madzi otayira otuluka, ndi madzi otayira zinyalala.

2. Chifukwa cha nthawi yochepa ya zinyalala zomwe zili mu malo otumizira zinyalala, kutulutsa kwa madzi otayira kumakhala kochepa.

3.Kuchuluka kwa zodetsa mu malo otumizirako zinthu ndi kotsika kuposa kwa zodetsa zina, ndipo kuchuluka kwa COD ndi pafupifupi 5000 ~ 30000mg/L.。

Makhalidwe akuluakulu a leachate ya zinyalala ndi awa:

①Pali mitundu yambiri ya zinthu zoipitsa zachilengedwe, ndipo ubwino wa madzi ndi wovuta (uli ndi zinthu zambiri zachilengedwe)

②Kuchuluka kwa zinthu zoipitsa komanso kusintha kwakukulu (kuchuluka koyamba kwa BOD ndi COD ndikokwera kwambiri, mpaka mamiligalamu makumi ambiri pa lita imodzi, pH ili pa kapena yocheperako pang'ono kuposa 7, B/C ili pakati pa 0.5-0.6, ndipo mphamvu za biochemical ndizabwino), nthawi zambiri, chiŵerengero cha COD, BOD, BOD/COD chimachepa ndi "zaka" za malo otayira zinyalala, ndipo alkalinity imawonjezeka.

③Ubwino ndi kuchuluka kwa madzi zimasiyana kwambiri: kuchuluka kwa madzi kumasiyana kwambiri malinga ndi nyengo (nyengo yamvula ndi yayikulu kuposa nyengo yachilimwe); kapangidwe ndi kuchuluka kwa zodetsa zinyalala zimasinthanso malinga ndi nyengo; kapangidwe ndi kuchuluka kwa zodetsa zinyalala zimasintha malinga ndi nthawi yotayira zinyalala.

Makhalidwe akuluakulu a leachate ya zinyalala m'mafakitale owotcha ndi awa:

①Kuchuluka kwa COD, BOD, ndi ammonia nayitrogeni (COD imatha kufika 40,000 ~ 80,000)

②Nthawi yophika ndi yayitali kuposa nthawi ya siteshoni yosamutsira.

Zinthu zazikulu zomwe zimapangitsa kuti zinyalala za kukhitchini zituluke:

①Zinthu zolimba zomwe zimapachikidwa kwambiri: Zinthu zosiyanasiyana zomwe zimapachikidwa zimakhala ndi kuchuluka kosiyana kwa zinthu zolimba zomwe zimapachikidwa m'malo okhazikika komanso okhala ndi colloidal, mpaka 60,000 mpaka 120,000 mg/L, zomwe zimafalikira kwambiri komanso zimakhala zovuta kuzilekanitsa;

②Mafuta ambiri: makamaka mafuta a nyama ndi ndiwo zamasamba, mpaka 3000mg/L mutatha kulandira chithandizo chisanachitike

③COD yokwera, nthawi zambiri yosavuta kuwonongeka, mpaka 40,000 mpaka 150,000 mg/L;

④pH yotsika (nthawi zambiri pafupifupi 3);⑤mchere wambiri.

Takulandirani kuti mudzafunse za malonda athu——Mankhwala a CLEANWARTER
