Method for quickly eliminating black odor of river channel of pumping station

Abstract

The invention discloses a method for quickly eliminating a black odor of a river channel of a pumping station, and belongs to the technical field of sewage treatment. The method comprises the steps ofadding a solid mixing medicament to a water body of the river channel to be treated, and adding 30-70 mg of calcium nitrate, 20-50 mg of calcium peroxide, 20-50 mg of sodium percarbonate, 50-100 mg of aluminum sulfate and 10-50 mg of glucose per 1 L of the water body, wherein the water body is oxygenated by an aeration system installed in the river channel. The method screens out, mixes and putschemical agents which have no side effects on microorganisms into the river channel, cooperates with the river channel for aeration, can quickly eliminate the black odor of the river channel of the pumping station, and greatly reduces the black odor removal time.

Description

technical field [0001] The invention relates to a method for quickly eliminating the black odor of rivers discharged by pumping stations, and belongs to the technical field of sewage treatment. Background technique [0002] Polluted river discharge from pumping stations in central urban areas mainly comes from the combined pumping station of the combined drainage system and the rainwater pumping station of the split drainage system. The river discharge in dry weather includes the discharge of the river in dry weather, the discharge of the river during the trial operation, the discharge of the river before the rain, the discharge of the river for maintenance, and the discharge of the river in cooperation with the construction. The main forms of river discharge in the main urban area of ​​Shanghai are pre-evacuation, non-point source pollution in rainy days, and peak flow overflow pollution in dry days, etc. Especially, the situation of river discharge before and after rainfal...

Problems solved by technology

The Chinese invention patent with the publication number CN102424446A discloses a method for treating black and odorous water bodies in urban rivers and lakes. The method uses a solid bottom mud restoration agent containing zeolite powder, activated carbon, oxygen enhancer, flocculant and adhesive Adding granules directly into the water body can significantly slow down the black and odor phenomenon in the water body. However, when this method is used to remove the black odor in the Fangjiang River, it takes a long time to remove the black odor. It usually takes at least three days to significantly improve the emission. The Black and Odor Phenomenon in the Black and Odor River
