Technical field
The utility model device relates to a kind of device that is used for light-catalyzed reaction research, is mainly used in the photocatalyst activity evaluation, degradation of contaminant dynamics research, and the mensuration that can be used as total organic carbon in waterbody (TOC).
Technical background
Handle at present the degraded that contains the organic pollution industrial wastewater, decolouring etc., mainly adopt materialization (absorption method, membrane separation process, extraction etc.) to add biological treatment, major defect is that to handle the volume that needs big, and the operating cost height brings secondary pollution.Be considered to have the water technology of prospect as the photocatalysis technology of one of high-level oxidation technology, but at present still can not large-scale application.The photocatalytic degradation technology realizes that one of industrialized key is to measure the reaction dynamics data of pollutant photocatalytic degradation.Present research majority is the apparent degradation kinetics (can not represent the degree of thorough mineralising fully, be the situation that explanation itself is decomposed) of detection of contamination.Exist simultaneously to obtain online data, therefore make dynamic (dynamical) data can not react the thorough degraded situation of organic pollution fully truly.Light-catalyzed reaction brings very big difficulty for the design of highly effective photocatalytic reactor because dynamics data lacks, and the industrial applications of photocatalysis technology is restricted.
Secondly the catalytic activity to photochemical catalyst does not have unified evaluation criterion and standard, and different researcher's equipment therefors differ greatly, the evaluation method difference, and the experimental result of different experiments chamber does not have comparativity.Make Many researchers do not done the work of a lot of repetitions, the waste of manpower financial resources, thus influenced the development of photocatalysis technology.
