The invention discloses an efficient energy-saving concentration treatment device for desulfurization wastewater. The concentration treatment device for the desulfurization wastewater comprises an evaporation tower, system wastewater is introduced into a water inlet pipe, flows to a center pipe, enters all water distribution branch pipes and is evenly sprayed downwards, a motor and a fan are started, and when the wastewater passes through a filler layer from the water distribution branch pipes from top to bottom and is subjected to one-time heat exchange with air introduced from an inlet air mesh, one-time evaporation is completed; the sprayed water falls on a water collection disc, a proper amount of smoke is supplemented to the air inlet pipe, the water temperature keeps at the design valve, and a wastewater circulation pump sucks the wastewater in the water collection disc into the water inlet pipe; in this way, the steps are circulated until the concentration of slurry of the watercollection disc reaches the required concentration, a discharging pipe is opened, and a concentration solution is discharged to a following treatment technology zone. According to the device, by effectively using the heat and waste heat of the system, the energy is saved, the investment is reduced, few devices are needed, the operation and maintenance cost is low, high concentration can be achieved, and in flexible cooperation with after-treatment of various forms, zero discharging of terminal wastewater is achieved.

The present invention relates to a photocatalyst unit. More particularly, the photocatalyst unit includes a body made of a plate with openings at upper and lower sides thereof and having one or more pairs of opposing lamp fixing means provided therein; ultraviolet radiation lamps each coupled to the lamp fixing means; a photocatalyst member coupled to the body and having a surface coated with a photocatalyst, wherein the photocatalyst member includes a plurality of plates disposed orthogonally to the ultraviolet radiation lamps, wherein the plates are disposed parallel to a flow direction of air and spaced to each other in order to form gaps between adjacent plates; and photocatalyst filters each disposed on upper and lower sides of the photocatalyst member and mounted on the body to cover upper and lower sides of the body, wherein the photocatalyst filters are applied with a photocatalyst.
