Water depth treatment technology using filter material synergistically modified with ultraviolet (UV) and ozone and equipment thereof

Abstract

The invention discloses a water depth treatment technology using a filter material synergistically modified with ultraviolet (UV) and ozone and equipment thereof. The water depth treatment technology is characterized by comprising the following steps: conveying sewage to equipment, and carrying out oxygenolysis after ozone optimizing treatment; carrying out adsorption treatment through a filtering section, and then generating .OH with strong oxidability under the combined action of low-concentration ozone and UV; further reducing bromate and other hazardous substances thereof, wherein the UV plays a sterilization role on water. Ozone is subjected to oxidation treatment by the equipment; filter material filtering and UV-coupled ozone oxidation processes are integrated; the ozone optimization section is arranged at the middle and the lower part of the filter section, so that the ozone fully contacts water, so as to play a good oxidation effect. Meanwhile, a by-product oxidized by ozone is easy to contact and react with the filter material, and the by-product oxidized by the ozone is removed. The adsorption treatment effect is improved by the modified filter material. By adopting the water depth treatment technology and the equipment thereof, the water treatment process is simplified, the problem of the existing ozone by-product is solved, the effluent quality of water treatment is improved, and the treatment cost is reduced.

Description

technical field [0001] The invention relates to a feedwater advanced treatment process and equipment thereof, in particular to a process and equipment for advanced treatment of feedwater ozone and UV synergistically modified filter material and removal of ozone oxidation by-products, belonging to the fields of municipal engineering and environmental engineering. Background technique [0002] With the increasing pollution of drinking water sources and the improvement of water quality standards, the ozonation process, one of the advanced treatment technologies for drinking water, has been more and more widely used. Ozone can effectively remove or reduce the degree of organic pollution and can disinfect water. At present, in order to deal with the pollution of water sources, municipal water supply water plants, whether they are newly constructed water plants or renovated water plants, basically adopt the combined advanced treatment process of ozone oxidation and activated carbo...

AI Technical Summary

Problems solved by technology

First of all, the problem of residual by-products of ozone oxidation. If the water source contains bromide, bromate will be produced after ozone oxidation. The removal of bromate by the above process is only the adsorption of activated carbon, and the removal rate is low.

Second, the process is cumbersome

Especially for the transformation of the existing traditional process, it is necessary to add multiple structures, and when the elevation of the existing treatment process is determined, adding treatment units between the structures will inevitably destroy the original hydraulic balance, or increase the lifting equipment to increase the energy consumption, or reduce the scope of use of subsequent structures
