FIELD: treatment facilities.
SUBSTANCE: invention concerns waste utilisation after industrial sewage treatment by reagents and can be applied in engineering industry and production of construction materials, namely mineral cementing materials. Method of waste utilisation after sewage treatment by reagents is applied to sewage suspension with 85-95% humidity where solid residual includes approximately 36% CaO and 35% SiO2 and involves suspension utilisation as water for lime and sand mix slaking in amount of 6-7% of the mix weight, mixing and further brick moulding and steam curing in autoclave.
EFFECT: waste suspension utilisation after sewage treatment by reactants in silicate brick production, wasteless technology of sewage treatment, reduced cost of waste burial and brick production costs.
