The article is devoted to the calculation and 3D modeling of the photocatalytic panel reactor for the degradation of dyes and phenol. To do this, the photocatalytic reactors of various types for the photodegradation of organic pollutants in aqueous solutions were theoretically examined. In our opinion the panel type photoreactors are the most rational. The prospect of photocatalytic treatment of wastewater from organic pollutants by the so-called methods of Advanced Oxidation Processes, among which the heterogeneous photocatalysis with the participation of such a catalyst as titanium (IV) oxide is most effective, is also noted. In order to determine the optimal design of such equipment various available in the literature types of photoreactors are considered. It is shown that the separation of powdered photo-catalysts can be successfully implemented using membrane modules. Based on theoretical analysis, the choice of the panel type photoreactor was substantiated and its calculation was carried out. It has been shown that for the uniform molar concentration of such pollutants as phenol and dyes (Congo red and Methylene blue), the different number of lamps and sections of the photoreactor are required. As a result, the more versatile design, the panel photoreactor is developed. The number of sections in it can be increased if necessary, and such reactor is capable of providing highly effective photo-destruction of pollutants of different genesis in sewage of various origins. According to the developed design of the photoreactor, its 3D modeling is carried out, which allows to visualize all the structural elements of such unusual type of special equipment.
