Abstract

The invention refers to methods of automatic control of the process for underground waters purification from sulphureted hydrogen and may be used by water-treatment plants and industrial enterprises with individual artesian wells. The method, according to the invention, includes the continuous sampling of the initial and treated water, adding to the initial sample a constant hydrogen peroxide dose, measurement of optical density of the samples at the wave length of 667 nm when adding the dimethylparaphenylenediamine and iron chloride solution, comparison of the obtained values and dosing of the hydrogen peroxide depending on these values.The result of the invention consists in increasing the control accuracy of the water purification process up to 0,05+-10%.Claims: 1Fig.: 1
