Abstract

The invention provides an efficient photocatalysis water treatment device. The efficient photocatalysis water treatment device comprises a tank body, a quartz tube, a backflow port, an extra-ultraviolet tube, a three-dimensional ceramic honeycomb net photochemical reaction chamber, a sewage distributor, a sewage port, an aeration port, an aeration assembly, a sewage draining port, a medicine distributing assembly, a medicine port, a coarse filtering net, a high-pressure backwashing device, a high-pressure water port, a tail gas recovering port and a reciprocating motion device; three ports are formed at the lower part of the tank body, namely, an organic sewage port, the aeration port and the medicine port; the three-dimensional ceramic honeycomb net photochemical reaction chamber for loading the extra-ultraviolet lamp and a nanometer TiO2 photocatalyst are formed at the upper part of the tank body; and the tail gas recovery port is formed at the upper part of the tank body.

Description

technical field [0001] The invention relates to a high-efficiency photocatalytic water treatment method and device, in particular to a treatment method and device for highly polluted organic sewage. Background technique [0002] With the acceleration of economic development and urbanization, the sites and highly polluted organic sewage caused by industrial and mining enterprises have seriously polluted the environment. Due to the changes and adjustments in the industrial structure and urban layout, some polluting enterprises such as chemical industry and metallurgy have relocated one after another, and some enterprises have closed down, resulting in continuous generation of polluted sites. Soil is an important material basis for human social production activities and an indispensable natural resource that is difficult to regenerate. Untreated contaminated sites will be chemical time bombs. Once a large-scale outbreak occurs, it will have an incalculable impact on the sustai...
