Embodiment 1

[0015] Dissolve the solid mixed medicament in water to make a mixed medicinal solution, then spray the mixed medicinal solution into the water area A of the above-mentioned river, wherein, in the water area A, every 1L of river water is added with 50mg calcium nitrate, 30mg calcium peroxide, 30mg Sodium percarbonate, 100 mg aluminum sulfate, and 50 mg glucose. The ORP and ammonia concentration changes in the water body of water area A were measured, and the black and odorous conditions (color and odor changes) of the water body were observed. The results are shown in Tables 1 to 3.

Embodiment 2

[0017] Dissolve the solid mixed medicine in a small amount of water to make a mixed medicinal solution, then spray the mixed medicinal solution into the water area B of the above-mentioned river, wherein, in the water area B, every 1L of river water is added with 30mg calcium nitrate, 20mg calcium peroxide, 20 mg sodium percarbonate, 50 mg aluminum sulfate, and 10 mg glucose. The ORP and ammonia concentration changes in the water body of water area A were measured, and the black and odorous conditions (color and odor changes) of the water body were observed. The results are shown in Tables 1 to 3.

Embodiment 3

[0019] Dissolve the solid mixed medicament in the water to be made into a mixed medicinal solution, then the mixed medicinal solution is sprayed in the water area C of the above-mentioned river, wherein, in the water area C, every 1L of river water is added with 70mg calcium nitrate, 50mg calcium peroxide, 50mg Sodium percarbonate, 100 mg aluminum sulfate, and 50 mg glucose. The ORP and ammonia concentration changes in the water body of water area A were measured, and the black and odorous conditions (color and odor changes) of the water body were observed. The results are shown in Tables 1 to 3.

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...
