The increasing quantity of municipal and industrial sewage is a growing menace to water-soil systems. This paper describes a method of disinfections of municipal wastewater treatment plant sludge with parallel immobilization of heavy metals. A special concern was devoted to immobilizing heavy metals in prepared organic-mineral manure. The main source of heavy metals is industrial sewage mixed with municipal sewage. The application of detritus basalt, which contains aluminosilicates connected with iron (di-and trivalent), calcium and magnesium and which places the function of natural sorbent and ion exchange material having strong relation to heavy metals has produced good results.
