Abstract
The
water quality diffusion and transport around archipelago have their own
uniqueness and complexity. On the basis of multinest 2D mathematical model
for currents around Zhoushan Islands, model for water quality prediction was
built. The pollutants discharge of Xiaogan Island was taken into
consideration and mathematical model for pollutant diffusion and transport in
accident discharge was studied. The influence on water quality in different
discharge intensity was calculated, which provided scientific basis for the
control results. It was observed that the concentration contours of CODMn
at 0.03 km2 in three conditions corresponded to standard discharge
at 0.90 mg l-1, accidental discharge at 1.02 mg l-1 and
extreme discharge at 1.42 mg l-1, respectively. Although discharge
point locates between the archipelago, diffusion of pollutants is rapid for
the fast-flowing waters of Zhoushan Islands, that provides good diffusion
conditions.
