[0018] The present invention is a bioremediation treatment process for black, odorous and eutrophic water bodies, as shown in the figure, and the specific implementation method is as follows:
[0019] (1) Source biological ecological interception system
[0020] An anaerobic biochemical pool is set at the sewage outlet on the river or lake bank. The anaerobic biochemical pool is a custom-made FRP tank reactor. The reactor is divided into a grid adjustment area, an anaerobic area, a contact reaction area and a sand filter area. Soft fillers are installed in the anaerobic zone and contact oxidation zone. The sand filter area is filled with sand and gravel. The lower layer is a gravel layer with a thickness of about 10cm-30cm, and the upper part is a sand layer with a thickness of about 80-150cm; PVC perforated water collection pipes are laid in the gravel layer. Sewage enters from the bottom of the anaerobic zone, and passes through the filler in the anaerobic zone and the fil...
