КАВИТАЦИОННАЯ ОБРАБОТКА ШАХТНЫХ ВОД

Abstract

Particularly important issue of protection of water resources from pollution by untreated sewage gets in the coal industry, companies which are characterized by a large volume of discharged mine water. Apart from contamination by mechanical and organic impurities, mine waters are characterized by a high salt content, which limits their comprehensive use in the national economy without proper cleaning, as well as a real danger pollution of surface and ground water. In connection with an accrual scarcity of freshwater and an increase in the number of discharge of industrial waste water becomes very important question of clearing and use of the latest technology for mine water. This allows, on the one side to reduce the use of drinking water for needs not related to drinking and domestic water supply, and on the other - to improve the health status of surface and ground water.
This paper examines the effect of cavitation on the degree of purification of mine water, the effect of various factors: duration of exposure cavitation in the water, setting of temperature parameters and the influence of the coagulant (aluminum sulphate) to the process of processing of mine water and also changes in the ionic composition of mine water before purification and after purification using of gravitational influence.
When exposed to cavitation destruction is observed at the molecular level, of chemical compounds and the elements present in the contaminated water, and further oxidation of broken connections. This will effectively purify highly polluted water, which in most cases include mine water Karaganda region. Given method allows to increase the quality of treated water, which leading to a more extended area of the use.
