Waste waters, particularly waste waters with radioactive contamination, are cleaned by a sorption-precipitating process, where the sorbent retaining cations are regenerated that is, activated, by a solution, the cationic component of which forms with anionic contaminations a precipitate, taking along cationic contaminations, and simultaneously sticking on the surface and within pores of the sorbent.

Method of producing an activated cation-retaining sorbent through

A technique is described for stiffening a biomass comprising mycelia fungi used for retention of heavy metal ions. The procedure involves dispersing a dry or native mycelium strain in a non-polar dispersion medium, agglomerating the resultant dispersion by adding a stiffening component and a surface active agent, and catalyzing the agglomerated mixture to yield stiffened granules.

Method of treating a biomass

Biomasses of mycelia of microorganisms, particularly of fibrous fungi used for retention of metal ions from solutions, particularly of uranium, radium, lead and similar are stiffened by adding polymerizable components to them by polymerization, and the product is subsequently mechanically granulated. The granulated product is then employed in cyclically repeated sorption processing of heavy metal ions by contacting it with solutions of such metals.

Separation of fission and corrosion products and of corresponding stable isotopes from liquid waste. Mycelia of fungi are used as sorbents for retaining said products on their surface and within their pores; the invention includes methods of activation or regeneration of the sorbent.
