Introduction: The inherent reason for the development of new technologies and technologies for urban sewage treatment is the result of the continuous pursuit of high-performance indicators such as high efficiency, low energy consumption, low cost, and low floor space. The application of different reactors is limited by technical, economic and theoretical conditions. These limitations are reflected in the research and development of aerobic bioreactors, which are affected by biological growth characteristics (biomass and activity), reactor form (fixed bed, suspended bed, and fluidized bed), and mass transfer conditions (oxygen supply) And solid-liquid separation (precipitation, filtration) and other constraints.

Features of sewage treatment in small towns: small scale of sewage treatment, large changes in water quality, lack of applicable technologies, lack of operation and management experience

Comprehensive sewage discharge standards: discharge standards for sewer water quality standards

Construction Standards for Sewage Treatment Projects in Small Towns: Proposed construction content and standards for sewage treatment projects in built-up towns below the county seat.

Appropriate process for sewage treatment in small towns: Ecological treatment of aerated biological filter in oxidation ditch of SBR reactor

online survey

What do you think are the reasons for the poor social and economic benefits of small town sewage treatment plants?

1. The wastewater collection effect is poor, and it cannot reach the expected sewage volume. 2. The one-time investment in the high and cold regions is high, and most of the processes are not applicable. 3. The imported technology needs to be digested and absorbed. 4. The domestic experience exchange is not smooth, and applicable and good craftsmanship cannot be promoted. 5. There is no post-evaluation mechanism.
