Abstract

The recycling of waste activated sludge (WAS) formed in the process of biological purification of sewage is an urgent ecological problem. In the present work, we consider various technological schemes for the utilization of WAS, namely: obtaining carbon adsorbent in the framework of low-temperature carbonization of WAS; synthesis in the framework of lowtemperature sintering of WAS- glass mixtures of composite adsorbent granules consisting from carbon and porous glass; low-temperature synthesis of foam glass from mixtures WAS-a fusible comminuted glass; synthesis of porous brick products in water-saving mode when using WAS with high humidity; production of porous carbonized ceramics using WAS and firing under oxygen deficiency conditions. The obtained results showed that on the basis of the developed technologies it is possible to obtain active adsorbents for water purification from dyes, for filtration of sewage from suspensions and brick products of various porosities with good mechanical properties.
