DTRO membrane cov cuab yeej ua ke nrog cov kev daws teeb meem

Angola Leachate Treatment Project

Qhov project nthuav dav

Qhov kev daws teeb meem ib leeg muab los ntawm Jiarong yog siv rau cov dej xau thiab lwm yam kev kho dej khib nyiab. Kev daws tau zoo rau cov neeg siv khoom hauv Angola kom txo cov dej khib nyiab. Tsis tas li ntawd, qhov permeate zoo tau raws li tus qauv tso tawm hauv zos.
