Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to a modular combined sewage treatment device. Background Art

[0002] With the acceleration of global urbanization and the improvement of industrialization, sewage treatment has become one of the key issues that need to be urgently addressed in the field of environmental protection. Traditional sewage treatment systems often rely on complex process flows and large equipment systems. These systems not only occupy a large area and have high investment costs, but also have many limitations in terms of treatment efficiency and flexibility. In particular, when faced with challenges of different water quality, water volume and space limitations, traditional systems are often difficult to respond flexibly; in order to overcome these limitations, modular combined sewage treatment devices have gradually emerged in recent years. The modular design concept emphasizes splitting the sewage treatment system into several independent functional modules. These modules can be freely combined and configured according to actual needs, thereby realizing the rapid construction, flexible adjustment and efficient operation of the sewage treatment system. This design method not only reduces construction costs and shortens the construction period, but also improves the adaptability and scalability of the system.

[0003] However, in the actual application of modular sewage treatment devices, how to effectively improve the performance of the two core links of filtration and stirring is still an urgent problem to be solved. The filtration link is the first step in sewage treatment, and its effect directly affects the load and efficiency of the subsequent treatment process; while the stirring link is directly related to the mixing uniformity of the reagent and sewage, which in turn affects the effects of subsequent reactions such as precipitation and oxidation; traditional modular sewage treatment devices often regard filtration and stirring as two independent processes, which are implemented by different mechanisms. Although this design method can meet basic functional requirements, it still needs to be optimized in terms of space utilization and equipment cost. Therefore, we make improvements to this and propose a modular combined sewage treatment device. Summary of the invention
