PROSPECTS OF USE activated sludge STATIONS OF AERATION AS ORGANIC FERTILIZERS
This work treats the problem of pollution of activated sludge from the city stations of aerations by ions of heavy metals. Its chemical composition and fertilizing value is treated here which let us to use it in agriculture as organo-mineral fertilizer. The main methods of treatment of sewage waste are given. A method of desorption of heavy metals from the activated sludge with the use of biosorption complex is submitted.
