Improving the deodorization of sewage pump stations in pumping stations

The sewage pump station is the main tool for transporting industrial and domestic sewage, but it is prone to producing odors during the production process, which has always been a headache. Sewage pump stations are divided into lift pump stations and rainwater pump stations. The main reason why these two types of pumping stations are prone to produce odorous gases is that anaerobic conditions are easily formed inside the drainage pipes. As a result, nitrogen-containing and sulfur-containing organic matter in the sewage will decompose into odorous substances. When the pumping station equipment is started and operated, it will cause turbulence in the water flow, causing the odorous substances that were originally generated and dissolved in the sewage to enter the air, thereby forming odorous pollution. So it is necessary toImproving the deodorization of sewage pump stations in pumping stations.

In the collection wells of most sewage pumping stations and merging pumping stations, the grid cleaning machine needs to continuously clean the garbage every day, emitting a foul odor during the cleaning process. In addition, during the maintenance of the pump equipment in the pump room, high concentrations of harmful gases will also instantly overflow from the inlet pipeline when disassembling and assembling the equipment.

The main reason for the odor generated by sewage pumping stations is due to the decay of organic matter in many sewage, and the main component of this odor is hydrogen sulfide. The hazards of hydrogen sulfide are relatively significant, mainly affecting human health and the environment. In addition, it affects people's normal life and work, reduces the quality of life of society and urban environment. So the main problem with deodorization in sewage pumping stations is to remove hydrogen sulfide gas.

The general methods for deodorization in sewage pumping stations include adsorption, absorption, biological deodorization, and high-energy ion methods, among which the ideal ones are biological deoxygenation and high-energy ion oxidation. For adsorption method, it is a common physical method that uses substances such as activated carbon or alum to absorb odorous substances and prevent the release of odors. The absorption rule is a chemical method that is relatively efficient, but it is also highly dangerous, so it is rarely used.

Biological method refers to the use of microorganisms in sewage pumping stations to remove oxygen from water bodies, generating other odorless substances. Microorganisms also parasitize on damp carriers to grow a thin biofilm. When odorants flow through this microbial area, they are oxidized into water and carbon dioxide, completing the deodorization process of odor.

The high-energy ion method utilizes the high-energy ion generation device of the sewage pump station, and delivers controllable positive and negative itchy ion air to the space emitting odor through the ventilation system. The ion air covers the pollution source, allowing the ions to react with the odorous gas, thereby reducing the concentration.

Improving the deodorization of sewage pump stations in pumping stationsThe collection and transportation of odors are also important, and the rationality of the odor collection and transportation design greatly affects the treatment effect of the entire odor control and treatment system. Generally, stainless steel square air ducts are used for collecting air ducts. The collection buckle of the air duct is directly connected to the cover plate of the collection well, and holes are opened on the glass cover plate according to the collected air volume and pressure.
