The process of purification of model solutions imitating wastewater of processing enterprises, in particular, containing highly dispersed and emulsified particles, such as lipids and salts of fatty acids, was studied by the cavitation-flotation method developed by the authors. Rational parameters of effective introduction of new cavitation-flotation technology of cleaning of these environments, in particular influence of technological parameters of process (pressure, air consumption, etc.) on structure of flotation foam and efficiency of cleaning are established. Have been shown that insoluble reagents, such as calcium oxide (hydroxide), to disperse and activate during cavitation. The process of cavitation destruction of methylene blue as a typical representative of nitrogen-containing compounds used in food and light industry in the presence of the oxidative system "hydrogen peroxide-potassium periodate" was studied. The influence of technological parameters on the separation of technological suspensions by cavitation-flotation method is investigated, and their influence on the parameters of flotation foam is analyzed.
Scientific and technological bases of flexible cavitation-flotation technology of sewage and liquid waste treatment containing highly dispersed and dissolved organic substances have been developed. A basic technological scheme for the implementation of this process is proposed, which can be easily adapted for use in typical chemical-technological processes and for innovative technologies, as well as for wastewater treatment generated in various industries.
