Description

Technical Field

[0001] The invention relates to sewage treatment equipment, in particular to integrated sewage treatment equipment. Background Art

[0002] The integrated equipment is simple to construct and occupies a small area. It is widely used in small and emergency sewage treatment projects. Domestic sewage mainly comes from people's daily water use, such as residential, school, hospital, public places and industrial toilets. The pollutants contained in domestic sewage are mainly organic matter and a large number of pathogenic microorganisms. The importance of disinfection is particularly highlighted during the epidemic period. Therefore, the pilot level of disinfection work in the newly built sewage treatment system has been significantly improved. In order to avoid the impact of bacteria and viruses in the water on the environment and people, disinfection and sterilization are required during the treatment process. Therefore, it is necessary to improve the existing integrated sewage treatment equipment to meet the current requirements of sewage treatment.

[0003] CN 204058014 U discloses a utility model patent for an environmentally friendly photovoltaic water treatment device, which has the functions of descaling, sterilization and algae removal, but its disadvantage is that it has a small application range and cannot meet the treatment requirements of domestic sewage.

[0004] CN 211999209 U discloses a utility model patent for an environmentally friendly photovoltaic water treatment device, which introduces photovoltaics into a simple flocculation sedimentation system. However, its disadvantage is that it cannot meet the treatment requirements for domestic sewage and requires artificial addition of agents.

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide an integrated sewage treatment equipment, which combines ozone disinfection and sludge reduction technology with the integrated sewage treatment equipment, thereby achieving the goal of eliminating the need for manual addition of disinfectants and significantly reducing the discharge of residual sludge. Ozone, as a green disinfectant, does not cause pollution during its preparation, use and discharge, and the ozone overflowing from the water also has the function of disinfecting and deodorizing the space. The disinfected water enters the water purification activated carbon and reverse osmosis device to provide drinking water. The power of the entire system is provided by photovoltaic panel components and solar batteries, which can be applied to emergency systems and field sites and other areas without power supply conditions. At the same time, a photovoltaic energy storage system is added to solve the problem of lack of power supply conditions. The system can operate independently without relying on any external supply.
