The sewage treatment system is completed by an upper computer, PLC, and an electric control actuator. The carrier is a container, which is flexible. According to the characteristics of decentralized domestic sewage, we intend to make use of our own advantages in container design and manufacturing, and integrate advanced biological sewage treatment technology into intelligent monitoring technology, such as wind, light, electricity, energy-saving storage technology, container modularization technology, mobile integration technology, etc., to realize the technical subversion of the traditional sewage treatment industry, and upgrade the traditional high-energy, large-scale and centralized sewage treatment mode to a low-carbon, intelligent and decentralized micro-ecological water circulation mode. By designing a new system and a new mode of use and service, the environmental protection industry can be greatly upgraded and eventually industrialized.
