Overview of Domestic Sewage: Domestic sewage refers to the wastewater discharged by residents in their daily lives. It mainly comes from residential buildings and public buildings, such as: residences, government offices, schools, hospitals, shops, public places and industrial enterprise restrooms, etc. Domestic sewage contains a large amount of organic matter (such as proteins, carbohydrates, fats, urea, ammonia nitrogen, etc.) and a large number of pathogenic microorganisms (such as parasite eggs and intestinal infectious diseases, etc.). The organic matter existing in domestic sewage is very unstable and prone to corruption and the formation of evil bacteria. Bacteria and pathogens multiply rapidly by taking organic matter in domestic sewage as nutrients, which can lead to the spread and prevalence of infectious diseases. Therefore, domestic sewage needs to be treated before being discharged.
Introduction to Domestic Sewage Treatment Equipment: The domestic sewage treatment equipment adopts membrane bioreactor technology (abbreviated as MBR), which is a new process combining biological treatment technology and membrane separation technology. It replaces the sedimentation tank in the traditional process and can efficiently carry out solid-liquid separation to obtain stable reclaimed water that can be directly used. It can also maintain a high concentration of micro-sludge in the sludge tank, with less residual sludge in the process, effectively removing ammonia. The suspended solids and turbidity in the effluent are close to zero, and the bacteria and viruses in the effluent are greatly reduced. It has low energy consumption and a small footprint. Its water source is taken from domestic sewage (such as shower drainage, washbasin drainage, laundry drainage, kitchen drainage, toilet drainage, etc.) and cooling water.
