THE EVOLVING TREND OF MOBILE INTEGRATED DOMESTIC SEWAGE TREATMENT EQUIPMENT

With the rapid development of science and technology in our country, domestic sewage treatment equipment is also gradually upgraded, and underground or semi-underground integrated domestic sewage treatment equipment is increasingly widely used. However, for the treatment of domestic sewage in temporary construction camps and post-disaster reconstruction camps, underground treatment equipment has shortcomings such as large area and easy idle resources. In contrast, mobile domestic sewage treatment equipment has the advantages of convenience, resource saving, and high flexibility, and has good application prospects in emergency treatment of domestic sewage. The article summarizes the treatment technology of mobile integrated domestic sewage treatment equipment in recent years; introduces the specific structure and treatment effect of mobile domestic sewage treatment equipment with physical and chemical methods, biological methods, combined technology and constructed wetlands as core technologies; Compare mobile and underground domestic sewage treatment devices from the perspective of resource utilization and long-term planning, highlighting the flexibility, economical and practicality of mobile domestic sewage treatment devices; by analyzing the situation of rural domestic sewage treatment, we can predict the future of rural domestic sewage treatment The model was discussed, and the operation mode of coexistence of small sewage treatment plants and mobile domestic sewage treatment units was proposed. The development trend of mobile domestic sewage treatment units was prospected, with an emphasis on the advancement of advanced catalytic oxidation and membrane separation processes. It has important theoretical and practical guiding significance.
