Problems solved by technology

If the wastewater carrying a large number of viruses or pathogenic bacteria flows into the surface water body through the discharge outlet, the virus will easily spread to the water source and enter the drinking water treatment and water supply system, endangering public health and human health
In addition, due to the fall of the discharge port or the turbulence of the outflow, the splashed water is easy to form aerosols, which increases the risk of infection for surrounding residents or passing pedestrians, and even triggers super-spreading events

Abstract

The invention provides a discharge outlet purification system and a purification method thereof. The purification system is carried at a discharge outlet of sewage, the sewage is discharged after being purified by the discharge outlet purification system, and the discharge outlet purification system comprises a dosing section, a pretreatment section, a filler treatment section, a biochemical treatment section and a filter membrane treatment section. According to the system, the space of the receiving water area of the discharge outlet is transformed, purification treatment of discharged waterof the discharge port is achieved, and the system has the advantages of being high in applicability, rapid, efficient, multifunctional, flexible in operation and the like.

Description

technical field [0001] The invention belongs to the technical field of municipal drainage and public health, and relates to a discharge outlet purification system and a purification method. Background technique [0002] While the increasingly perfect urban drainage system provides convenience for the transportation of various types of wastewater in cities and towns, problems such as the spread of germs and water pollution caused by the urban drainage system in the process of collecting, transporting and discharging wastewater have also attracted widespread attention from all walks of life. According to reports, some cities in my country have detected cholera and other viruses or pathogenic bacteria at the discharge outlets. Relevant studies have shown that the urban drainage system is an important carrier library for microorganisms, and there are a variety of human viruses and pathogenic bacteria. [0003] At present, the novel coronavirus (2019-nCoV), which is widely conce...
