Angola Leachate Treatment Project

Tsatanetsatane wa Ntchito

Yankho loyimitsa limodzi loperekedwa ndi Jiarong limagwira ntchito pa leachate ndi zina zovuta zothira madzi oyipa. Yankho lake linali lothandiza kwa kasitomala ku Angola kuti achepetse kutulutsa kwamadzi oyipa. Komanso, mtundu wa permeate unkagwirizana ndi mulingo wotayira m'deralo.

Ntchito ya polojekiti

Sikelo yayikulu: 0.94 miliyoni m ³   leachate, pulojekiti yayikulu kwambiri yazadzidzidzi padziko lonse lapansi.

Chovuta chachikulu: kukhathamiritsa kwamagetsi kwapamwamba kwambiri, ndende ya ammonia komanso mulingo wokhazikika wamadzimadzi otayira.

Ndandanda ya polojekiti yayikulu:

Perekani matani 800/d kulowa mkati mwa mwezi umodzi

Perekani matani 2,000/d kulowa mkati mwa miyezi itatu

Kuchita bwino kwambiri: ma seti 18 a makina a Jiarong adakonzedwa. Ubwino wa permeate unakwaniritsa mulingo wotayira utsi wamba.
