METHOD OF PRODUCTION OF THE REACTANT FOR THE BACTERICIDAL TREATMENT AND DEHELMINTOZATION OF THE SEDIMENTS OF THE SEWAGE PURIFICATION FACILITIES AND THE METHOD OF THE BACTERICIDAL TREATMENT AND DEHELMINTOZATION OF THE SEDIMENTS OF THE SEWAGE PURIFICATION FACILITIES Russian patent published in 2007 - IPC C08H1/06 C07C227/28 C02F11/00 

FIELD: municipal sanitary and disinfection services; production of reactants and the methods for bactericidal treatment and dehelmintization of the sediments of the sewage-purification facilities.

SUBSTANCE: the invention is pertaining to the bactericidal treatment and dehelmintization of the sediments of the sewage-purification facilities. Preliminary they determine the length and the width of the sludge drying bed, the space intervals between the insertion points, the depth of the sediment layer, its density, humidity and the specific dose of 1М reactant in terms of the absolutely dry substance of the sediment. The consumption of the reactant solution per one sludge drying site is calculated proceeding from the following mathematical expression:

and consumption the reactant solution per one place of its introduction is calculated proceeding from the mathematical expression:

where - the consumption of the solution_{per one sludge drying site, liters; - the consumption of the reactant solution introduction per one place of introduction, liter; L is the length of the sludge drying site, m; b is the width of the sludge drying site, m; h is the depth of the sediment layer, m;_ ρsedim.humidity is the density of the sediment, kg/m³;Whumidityoftreat.sed. is humidity of the treated sediment,%; d^spec reactant - specific dose makes 10 mmole of the reactant/kg of the absolutely dry substance of the sediment. The reactant is produced using the water-thermal treatment at presence of the alkali of the wastes containing the animal proteins. The wastes, water and alkali are taken in the ratio of 1:(1.8-2.0):(0.38-0.46), the treatment is conducted at the temperature of 160-180°С for 25-30 minutes. The technical result of the invention is the increased availability of the reactant and the increased efficiency of the treatment of the sediment.}

EFFECT: the invention ensures the increased availability of the reactant and the increased efficiency of the treatment of the sediment.
