Problematika síranů v odpadních vodách z výroby magnesiumbisulfitové buničiny.

Abstract

A Bachelor thesis is focused on teoretic ways of removing a sulphates from wastewaters, focusing on wastewaters from production of magnesium-bisulphite pulp. Paper and pulp industry belong to serious sulphates polution sources for wastewaters. There is an enviromental polution by sulphates during magnesium-bisulphite pulp production and sulphur have to be added in a form of sulphur dioxide. The thesis describes sulphate sources in different parts of the pulp production technology, further there is described a testing procedure for its laboratory controling and testing method for determination of sulphur in the wastewaters in Biocel Paskov a.s.
