The invention discloses a multistage
treatment system for riverway
discharge port
virus prevention and control and an operation method. The multistage
treatment system is characterized in that the multistage
treatment system is composed of an oxidant supply module, an
ultraviolet oxidation combination module and a biological and ecological treatment module; and the oxidant supply module is arranged near a riverway
discharge port and used for supplying
hydrogen peroxide, a
chlorine dioxide solution,
ozone and other green oxidants to the
ultraviolet oxidation combination module; the ultravioletoxidation combination module is used for efficiently inactivating viruses in water discharged from a
discharge port through the combined action of
ultraviolet rays and various oxidants, and has the functions of water purification and
odor removal; the biological and ecological treatment module is used for realizing advanced treatment of water discharged from the discharge port through the
decomposition and assimilation of microorganisms, the interception and
filtration of a filter membrane and the adsorption and absorption of
plant root systems. Compared with the prior art, the
system has theadvantages of good environmental, ecologic, social and
economic benefits and the like, and realizes the purposes of
virus prevention and control,
water quality purification and stink removal of the water of the discharge port.
