Grease and grime discharged from sewers is one of the major sources of pollution in the urban environment. If these pollutants are not properly disposed of, they pose potential risks to the environment and human health. Therefore, how to deal with grease and dirt in sewers has become an important issue.

Grease in sewers mainly comes from household sewage, food waste, industrial wastewater and so on. If not treated professionally, these oily substances will adhere to the inside of the pipes and form serious blockages, which in turn will affect the normal operation of the drainage system. The traditional way of treatment is to use manual cleaning or use chemicals for cleaning. But these methods are not only troublesome to operate, the effect is not satisfactory, and the use of chemicals will also be harmful to the environment and human health.

With the enhancement and progress of science and technology, there are many new treatment programs, the following briefly introduces a few:

1. Biodegradation method: the use of certain biological strains of bacteria, such as fat decomposition bacteria, etc., degradation treatment in the sewer, the pollutants such as fats and oils are decomposed into carbon dioxide and water and other harmless substances. This method has no pollutant residue and very little impact on the environment.

2. High-pressure water jetting method: Through high-pressure water jetting, the accumulation in the sewer will be flushed clean. This method is simple, fast and effective, which can effectively reduce the cost of pipeline maintenance and reduce the safety risk of manual operation.

3. Physical adsorption method: the use of physical adsorption materials, such as charcoal, fibers, adsorbent resin, etc., will be adsorbed and fixed on the surface of the material in the sewer of organic matter, to achieve the purification effect. This method not only protects the environment and reduces pollution, but also recovers part of the organic material, which can be converted into energy.

In short, the treatment of oil in the sewer is very important, not only related to the environment and human health, but also directly affect the efficiency of the city sewage system. Therefore, we should pay attention to daily hygiene and garbage classification, strict control of grease and other pollutants discharged, at the same time, all walks of life should also increase investment in scientific research, and actively explore new ways to deal with grease, to make a greater contribution to the cause of environmental protection.
