Ingaba uyazi? Ukongeza kwinkunkuma efuna ukulungiswa, i-leachate yetiphu nayo ifuna ukulungiswa.
Ngokweempawu zenkunkuma evuzayo kwitiphu, inokwahlulwa ibe: kwisikhululo sotshintshiselwano kwitiphu evuzayo, inkunkuma yasekhitshini, inkunkuma yetiphu, kunye neleachate yetiphu yezityalo.
Zeziphi iimpawu zezi ntlobo zine zeliti yokulahla inkunkuma?
Iimpawu zesikhululo sotshintshiselwano siyayeka:
1. Mininzi imithombo engundoqo yamanzi amdaka: ikakhulu amanzi amdaka asekhaya, ukugungxulwa kwamanzi amdaka, kunye nelehate yetiphu.
2. Ngenxa yexesha elifutshane lokuhlala kwinkunkuma kwisikhululo sokuhambisa inkunkuma, ukukhutshwa kwe-leachate kuncinci.
3.Ukuxinwa kwezinto ezingcolileyo kwisikhululo sokudlulisa kungaphantsi kunezinye izinto ezingcolileyo, kwaye ukuxinwa kweCOD malunga ne-5000 ~ 30000mg / L..
Iimpawu eziphambili ze-leachate yetiphu zezi:
①Kukho iintlobo ezininzi zezinto ezingcolisa izinto eziphilayo, kwaye umgangatho wamanzi untsokothile (uqulethe intaphane yezinto eziphilayo)
②Uxinzelelo oluphezulu lwezinto ezingcolisayo kunye notshintsho olubanzi (i-BOD yokuqala kunye ne-COD yogxininiso luphezulu, ukuya kuthi ga kumashumi amawaka eemiligram ilitha nganye, ixabiso le-pH liphantsi okanye lingaphantsi kancinane kune-7, i-B / C iphakathi kwe-0.5-0.6, kunye iipropati ze-biochemical zilungile) , ngokuqhelekileyo, i-COD, i-BOD, i-BOD / COD ratio iyancipha "ngeminyaka" yokulahla inkunkuma, kwaye i-alkalinity iyanda.
③Umgangatho wamanzi nobungakanani bamanzi buyohluka kakhulu: ubungakanani bamanzi buyohluka kakhulu ngokwamaxesha onyaka (ixesha lemvula lingaphezulu kunelonyaka elomileyo); ukubunjwa kunye nokuxinana kwezinto ezingcolisayo nazo ziyatshintsha kunye namaxesha onyaka; ukwakheka kunye nokuxinana kwezinto ezingcolisayo kuyatshintsha kunye nexesha lokulahla inkunkuma.
Ezona mpawu ziphambili zokulahla inkunkuma kwizityalo ezitshisayo zezi:
①Izigxina eziphezulu zeCOD, BOD, kunye ne-ammonia nitrogen (COD inokufikelela kwi-40,000~80,000)
②Ixesha lokubilisa lide kunelo lesikhululo sokudlulisa.
Iimpawu eziphambili zenkunkuma ye-leachate yasekhitshini:
①Izinto eziqinileyo eziphezulu ezimisiweyo: I-leachates ehlukeneyo inemilinganiselo eyahlukeneyo yezinto eziqinileyo ezimisiweyo kwi-settleable state kunye ne-colloidal state, ukuya kwi-60,000 ukuya kwi-120,000 mg / L, kunye ne-dispersion ephezulu kwaye kunzima ukuhlukana;
②Umxholo weoli ephezulu: ubukhulu becala ioli yezilwanyana kunye nemifuno, ukuya kuthi ga kwi-3000mg / L emva kokunyangwa kwangaphambili
③I-COD ephezulu, ngokuqhelekileyo kulula ukuhlanjululwa kwe-biodegrade, ukuya kwi-40,000 ukuya kwi-150,000 mg / L;
④pH ephantsi (ngokuqhelekileyo malunga ne-3);⑤ityuwa eninzi.
