Abstract

Based on the studies into ionic—dispersion compositions of sewage water after mining and processing of niobium ore of the Lovozero deposit, it is substantiated to be expedient to convert some pollution agents from solution to suspension state. A combined process is proposed for treatment of mine wastewater, which is 94% of total sewage water of mining and processing, by integrating coagulation, sorption and flotation techniques. The mathematical model of aggregation of suspension particles with regard to the hydrodynamic mode of coagulation is suggested. The model makes it possible to predict material and dispersion compositions of a new multi-phase system under different temperatures towards automation of the wastewater treatment process. The solution on forming surface properties of activated aqueous dispersions of air using a modified finely dispersed sorbent with intent to intensify the wastewater purification process.
