What are the key problems in solving domestic sewage?

Domestic sewage is the wastewater discharged from the daily life of residents, mainly in residential buildings and public buildings, such as residences, institutions, schools, hospitals, shops, public places and toilets of industrial enterprises. The pollutants contained in domestic sewage are mainly organic matter and a large number of pathogenic microorganisms. The organic matter in domestic sewage is extremely unstable and easy to decay and produce foul odors.

Bacteria and pathogens multiply in large numbers by feeding on organic matter in domestic sewage. <

Domestic sewage is the wastewater discharged from the daily life of residents, mainly in residential buildings and public buildings, such as residences, institutions, schools, hospitals, shops, public places and toilets of industrial enterprises. The pollutants contained in domestic sewage are mainly organic matter (such as protein, carbohydrate, fat, urea, ammonia nitrogen, etc.) and a large number of pathogenic microorganisms (such as parasite eggs and intestinal infectious viruses). The organic matter in domestic sewage is extremely unstable and easy to decay and produce foul odors.

Bacteria and pathogens multiply in large numbers by feeding on organic matter in domestic sewage, which can lead to the spread of infectious diseases. Therefore, domestic sewage must be treated before discharge.

Wastewater treatment is a complex technology that often faces a variety of problems and challenges, but here are a few of the most common ones:

1.Equipment aging problem: With the increase of use time, the equipment may be aging or damaged, such as pipe blockage, equipment wear and tear, liquid hopper, etc.

2.Sludge treatment problems: Sludge treatment after sewage treatment may have difficulties in storage, transportation and treatment, especially for areas with high waste discharge standards.

3.Lack of funding: The implementation of laws and regulations related to wastewater treatment and wastewater discharge requires a lot of costs. Moreover, in some areas, there is a shortage of sewage treatment plants, even in areas that have not yet been fully built.

4.Running cost issues: Running costs are an important consideration for wastewater treatment facilities. Typically, treating more wastewater requires more electricity consumption, use of chemicals used to treat wastewater, etc.

5.Discharge standards: Since sewage treatment involves wastewater discharge and environmental protection, there may be differences in discharge standards in various regions, in this case, how to control pollution and achieve a virtuous cycle of environmental protection and economic development has become a problem.

These problems have an impact on the efficiency and quality of wastewater treatment and need to be fully addressed and addressed.
