Underwater bacteria distributing process for eliminating black-odor in river channel

The invention discloses an underwater bacteria distributing process for eliminating black-odor in a river channel, and relates to the technical field of water quality purification. The problem that anexisting reagent can only eliminate single pollution and cannot completely remove the black-odor in the river channel is solved. The underwater bacteria distributing process for eliminating the black-odor in the river channel comprises the following steps that (1) bacterial culture is carried out, specifically, compound anaerobic bacteria, compound aerobic bacteria and compound photosynthetic bacteria are cultured, the mass fraction of each cultured bacteria solution is 1,000 parts, and the concentration is 11 ppm; and (2) addition in a river is carried out, specifically, a bacteria distributing pipe device is used for adding bacteria to the river through a water pump, underwater penetration of a bacteria distributing pipe is adjusted according to the water depth, the anaerobic bacteria,the aerobic bacteria and t
