Abstract—One of China largest river, Songhua River was other emergent treatment. Height of media layer was
polluted due to the explosion at a PetroChina factory in Jilin 700mmGAC and 300mmsand. The existing conventional
province in 2005. A full scale test was carried out to investigate treatment process is shown in figure 1 and the emergent
the removal of nitrobenzene in the raw water from polluted treatment process is shown in figure 2.
Songhua River. The removal and control effects of nitrobenzene
by using Powered Activated Carbon (PAC) absorption and
Granular Activated Carbon (GAC) filtration as emergent
treatments were studied. The results showed that PAC dosage
could change from 30mg/L to 50mg/L according to the variation
of nitrobenzene concentration in raw water. The dosing point of
PAC was at the intake of water source and enough adsorption
time could be guaranteed by means of the water transportation
