Concept of decentralized sewage treatment

There are mainly two ways of sewage treatment: centralized treatment and decentralized treatment. The centralized treatment can treat wastewater efficiently and stably, and realize the discharge of wastewater up to standard, which plays an important role in improving the quality of water environment. But at the same time, it also has the disadvantages of huge pipe network construction investment, large area, high engineering difficulty and excessive operation cost. The decentralized sewage treatment refers to the use of small advanced sewage treatment facilities to realize the nearby treatment and utilization of domestic sewage. This treatment technology has the advantages of lower cost of pipe network construction and maintenance, small floor area, less environmental impact, strong adaptability, flexibility and so on. In addition, it can also realize on-site reuse, which is more in line with the requirements of reclaimed water reuse. As a new mode of domestic sewage treatment at home and abroad, the decentralized sewage treatment technology has been paid more and more attention.

Significance of decentralized sewage treatment

The scattered rural areas pose challenge to the treatment of sewage. In this case, we should choose to recycle the treated sewage on the spot. Only in this way can sewage be treated efficiently, resources and money be saved, and sewage can be recycled more efficiently and profits can be increased. Therefore, the decentralized sewage treatment is considered to be a better method by most of scientists. This may be a more economical and efficient method than other sewage treatment methods.
