Abstract

The present invention discloses a device for rapidly disinfecting and removing disinfection byproducts. The device comprises: an aeration tank, which has an inflow port, an aeration tank outlet, and atank body, wherein the upper end surface of the tank body is provided with a tank cover, the tank cover is provided with a ventilation port, and the bottom of the tank body is provided with an aeration head; and a photo-reactor, in which a photo-reactor inlet and a flow outlet are arranged, wherein the photo-reactor inlet is communicated with the outlet pipeline of the aeration tank, and ultraviolet light is generated in the photo-reactor. In addition, the invention further discloses a method for rapidly disinfecting and removing disinfection byproducts by adopting the device. The method comprises the following steps: introducing to-be-treated liquid into the aeration tank from the inflow port, carrying out aeration; after aeration, introducing the liquid into the photo-reactor, carryingout photolysis in the photo-reactor to obtain a disinfected liquid; and making the disinfected liquid flow out from the flow outlet; wherein the to-be-treated liquid is drinking water. The device canrealize rapid disinfection, has an excellent disinfection effect, and can synchronously remove disinfection byproducts.

Description

technical field

[0001] The invention relates to the field of water treatment, in particular to a disinfection device and method. Background technique

[0002] Disinfection is an essential step in the drinking water treatment process. The widespread use of disinfection processes can effectively suppress the spread of many infectious diseases. However, the reaction between the disinfectant used in the disinfection process and the natural organic matter in drinking water will lead to the generation of disinfection by-products (DBPs for short).

[0003] Since chloroform was first discovered in sterilized drinking water in 1973, there have been, for example, trihalomethanes (THMs for short), haloacetic acids (HAAs for short), haloacetonitriles (HANs for short), and haloacetaldehydes (HALs for short). ) and more than 800 kinds of DBPs were detected and identified. And DBPs will cause a series of negative effects on human health, such as carcinogenicity, miscarriage, and chronic...
