Description
Technical Field
The invention belongs to the technical field of municipal drainage and public health, and relates to a combined purification method suitable for controlling pathogens at a discharge port.

It has been reported that some cities in China have detected viruses or pathogenic bacteria such as cholera at the discharge outlet. Related researches show that the outlet of the river channel is an important carrier library of microorganisms, and various human viruses and pathogenic bacteria exist.
The main routes for live viruses to reach the discharge include: the domestic sewage generated by virus infectors enters a combined drainage pipe network, and the viruses reach a discharge port and are discharged into surface water in rainy days; the split-flow rainwater pipeline with the rain and sewage mixed connection also has the problems; third, the surface runoff entraps the surface viruses to enter a shunt rainwater pipe network; sputum, droplets, touch articles and the like generated by virus infected persons outdoors enter a rainwater port through rainwater washing, and then enter a drainage system; the deposits in the drainage pipeline provide favorable environment for virus propagation and propagation, and the deposits carrying viruses are discharged through a discharge port when released into the river in rainy days.
The virus has a plurality of ways to enter a drainage pipe network, and the sources of the virus are extremely dispersed, so that the invasion and inoculation of the virus are not easy to be stopped from the sources of a drainage system. But the waste water in the drainage network will eventually be discharged from the discharge opening. In contrast, virus killing is more feasible at the drain at the end of the drainage system.
In view of the above, there is a need to develop a novel technique for in situ elimination of virus in the exhaust port.
