Ngaba uyazi? Ukongeza kwinkunkuma ekufuneka ihluzwe, inkunkuma ephuma kwi-dumpling leachate nayo kufuneka ihluzwe.
Ngokweempawu ze-leachate yokulahla inkunkuma, inokwahlulwahlulwa ibe: i-leachate yokulahla inkunkuma kwindawo yokuhambisa inkunkuma, i-leachate yenkunkuma yasekhitshini, i-leachate yokulahla inkunkuma kwindawo yokulahla inkunkuma, kunye ne-leachate yokulahla inkunkuma kwindawo yokulahla inkunkuma.
Zithini iimpawu zezi ntlobo zine zenkunkuma ephuma kwi-leachate?
Iimpawu ze-leachate yesitishi sokudlulisa:
1. Kukho imithombo emininzi ephambili yamanzi amdaka: ikakhulu amanzi amdaka asekhaya, amanzi amdaka ahlanjwayo, kunye nenkunkuma ephuma kwi-dumpling leachate.
2. Ngenxa yokuba inkunkuma ihlala ixesha elifutshane kwindawo yokuthutha inkunkuma, imveliso yenkunkuma ephuma kwinkunkuma incinci.
3.Uxinzelelo lwezinto ezingcolisayo kwisikhululo sokudlulisa luphantsi kunolo lwezinye izinto ezingcolisayo, kwaye uxinzelelo lweCOD lumalunga ne-5000~30000mg/L..
Iimpawu eziphambili ze-leachate yokulahlwa kwenkunkuma zezi:
①Kukho iintlobo ezininzi zezinto eziphilayo ezingcolisayo, kwaye umgangatho wamanzi uyinkimbinkimbi (uqulethe izinto ezininzi eziphilayo)
②Uxinzelelo oluphezulu lwezinto ezingcolisayo kunye notshintsho olubanzi (uxinzelelo lokuqala lwe-BOD kunye ne-COD luphezulu, ukuya kuthi ga kumashumi amawaka eemiligrami ngelitha, ixabiso le-pH lingaphantsi okanye lingaphantsi kancinci kune-7, i-B/C iphakathi kwe-0.5-0.6, kwaye iipropati ze-biochemical zilungile), ngokubanzi, umlinganiselo we-COD, i-BOD, i-BOD/COD uyancipha "ngobudala" bendawo yokulahla inkunkuma, kwaye i-alkalinity iyanda.
③Umgangatho wamanzi kunye nobungakanani bawo bahluka kakhulu: ubungakanani bamanzi buyahluka kakhulu ngokwexesha lonyaka (ixesha lemvula ngokucacileyo lingaphezulu kunexesha elomileyo); ukwakheka kunye noxinano lwezinto ezingcolisayo nako kuyatshintsha ngokwexesha lonyaka; ukwakheka kunye noxinano lwezinto ezingcolisayo kuyatshintsha ngexesha lokulahlwa kwenkunkuma.
Iimpawu eziphambili ze-leachate yenkunkuma kwizityalo ezitshisayo zezi:
①Amanqanaba aphezulu e-COD, i-BOD, kunye ne-ammonia nitrogen (i-COD ingafikelela kwi-40,000~80,000)
②Ixesha lokubilisa lide kunelo lesitishi sokudlulisa.
Iimpawu eziphambili zenkunkuma yekhitshi ephumayo:
①Izinto eziqinileyo ezixhonyiweyo kakhulu: Iileachats ezahlukeneyo zinemilinganiselo eyahlukeneyo yezinto eziqinileyo ezixhonyiweyo kwimeko ezinzileyo kunye nemeko ye-colloidal, ephezulu ukuya kwi-60,000 ukuya kwi-120,000 mg/L, enokusasazwa okuphezulu kwaye kunzima ukwahlulahlula;
②Umxholo ophezulu weoyile: ikakhulu iioyile zezilwanyana kunye nemifuno, ukuya kuthi ga kwi-3000mg/L emva konyango lwangaphambi konyango
③I-COD ephezulu, edla ngokuba lula ukuyibola, ukuya kuthi ga kwi-40,000 ukuya kwi-150,000 mg/L;
④i-pH ephantsi (ngesiqhelo malunga ne-3);⑤umxholo wetyuwa ephezulu.
