Wastewater from aquacultural drainage river, which was
located in Songjiang Modern Agricultural Ecological Park
(Shanghai, China), was selected as objective in the present
study. The length and width of the selected aquacultural drainage
river were 600 m and 6.5 m, respectively. The average water depth
was 1.2 m, and the highest water depth could reach 1.65 m when breeding peak arrived. The bank of river was totally hard cement,
the average length of bank was 4 m, and the slope angle was 45◦.
There was a water outlet in every aquacultural pond, through
which the wastewater in aquacultural ponds could drain away to
the selected river and the average amount of inlet aquaculture
wastewater was 2590 m3/d.
