| Summary: | The Day-Nhue river system, which locates in the important economic region of the
northern plains, covers a natural surface of 7949 km². The pollution of the Day-Nhue river syst em
was mainly due to receiving untreated/ ineffective untreated wastewater discharges from the
different sources in the basin. This paper focused on the industrial wastewater sources. Our
purposes are to i) collect information about the number and sizes of industrial production factories
and traditional production v illages; ii) establish the database of wastewater quality r eleased from
six main industrial production branches in the basin. The results obtained from our investigation
during 1/2007–12/2009 showed that the total wastewater discharge from industrial production
factories and traditional production villages r eached to 100,000m
3
/day and 45,000-60, 000m
3
/day,
respectively. The wastewater quality of some industrial production branches exceeded the
National technical regulation on industrial wastewater QCVN 24:2009/BTNMT. Most traditional
production villages caused serious organic pollution. |
