| Popis: | Wastewater from various industrial productions is the most difficult task for a designer in the field of developing an effective treatment scheme, since their composition and properties are extremely diverse, and treatment methods are possible, both chemical and physico-chemical, and biological. To select the most effective method for treating a particular type of wastewater, it is necessary to establish in what phase-dispersed states the impurities are. The authors of this article supplemented the existing classification of phase-dispersed states of pollution in wastewater with transition states: ultra-weighted, post-colloidal and atomically dissolved. For the simultaneous separation of contaminants that are in several groups of states according to the above classification, a dispersion phase separator has been developed, which includes several sequentially located purification zones and replaces large-sized and expensive facilities. On the developed installation, computer simulation was carried out in the ANSYS program in order to obtain streamlines and pressure of the fluid flow, velocity vectors in 3D format with their values, and the efficiency of the installation was determined. For the most efficient assessment of the wastewater treatment process in the phase separator, an automated control system has been developed in the OVEN program. Shut-off and control valves were selected, instrumentation was installed, allowing the operator to carry out phased control of the main types of pollution. In order to test the effectiveness of the dispersion separator, experiments were carried out on wastewater of various compositions from several industrial productions. The obtained results make it possible to recommend the phase separator as a facility for preliminary wastewater treatment for a number of industrial enterprises. |
