Variable landfill leachate maitiro

Complex zvinosvibisa zvirimo

Yakapfuma organic zvinhu, kureva yakakwira COD, BOD

High ammonia (NH ₃ -N) zviri mukati

Kuwanda kweiyo heavy metal ions uye salinity

DTRO membrane michina yakasanganiswa nemhinduro dzinoshanda

Angola Leachate Treatment Project

Project Detail

Iyo yekumira-imwe mhinduro inopihwa naJiarong inoshanda kune leachate uye mamwe akaomarara emarara emvura. Mhinduro yacho yaive inoshanda kune mutengi muAngola kuderedza kubuda kwetsvina. Zvakare, iyo permeate quality yakasangana neyako effluent discharge standard.

Chirongwa cheprojekiti

Iyo yakanyanya kuyerera mwero ndeye 1.5 L/s.

Muyero wepamusoro wekuyerera kwekurapa kwedhizaini iyi unogona kuita 5.4 m³/h kana 120m³/h, zvichienderana nezvinodiwa nemutengi.

Iyo dhizaini yekurapa inokwana 250 m ³ /d ine 90% yekushandisa simba.

Chirongwa cheprojekiti

Chikero chikuru: 0.94 mamiriyoni m ³   leachate, chirongwa chikuru chekurapa chekukurumidzira pasi rose.

Dambudziko hombe: yakanyanya kukwirisa magetsi conductivity, ammonia concentration uye yakanyanya kuomarara effluent discharge standard.

Yakadzika chirongwa chechirongwa:

Goho 800 tons/d permeate mukati memwedzi mumwe

Goho 2,000 tons/d permeate mukati memwedzi mitatu

Kunyanya kushanda zvakanaka: 18 seti yeJiarong mudziyo masisitimu akarongwa. Hunhu hwepermeate hwainyatsoenderana nemwero wepanobuda tsvina.

New Biz modhi: Jiarong inodyara mukushanda kwepurojekiti uye inobhadharisa mubhadharo wekurapa patani yemvura yetsvina yakabatwa.

Hunhu hwemvura yakasvibira:
