摘要：

The new method for treatment of waste waters from tanneries containing chrome and large amounts of other inorganic compounds has been studied. It was found that the addition of cement at suitable temperature and pH results in a decrease of Cr(III) and Fe(III) contents. The method has been verified in practice in five tanneries. It is very simple, cheap and effective in all cases with very different composition of tannery chrome-containing wastes.
