Abstract

Przedmiotem zgłoszenia jest sposób oczyszczania kwaśnych wód gruntowych z toksycznych związków chromu polegający na tym, że wodę gruntową przepuszcza się przez półprzepuszczalną barierę reaktywną, która zawiera dwie warstwy, przy czym warstwę pierwszą stanowi mieszanka piasku kwarcowego z naturalnym materiałem zawierającym glinokrzemian, w którego strukturze krystalicznej znajduje się Fe<sup>2+,</sup> a warstwa druga wykonana jest z rozdrobnionego kamienia wapiennego.The subject of the application is a method of purifying acidic groundwater from toxic chromium compounds by passing the groundwater through a semi-permeable reactive barrier, which contains two layers, the first layer being a mixture of quartz sand with a natural material containing aluminosilicate, the crystal structure of which contains Fe<sup>2+,</sup> and the second layer is made of crushed limestone.
