The necessity of studying organic waste as a secondary energy resource for a waste-heat boiler with further use of the resulting ash for the adsorption of heavy metal ions is shown. The adsorptive purification of waste water from copper ions by ash of organic waste is considered. The chemical composition and technological characteristics of organic biomass, the characteristics of the boiler and the toxicity of the resulting ash have been determined. The chemical composition of the ash was obtained. The isotherm of adsorption in static conditions and the output curve of adsorption in dynamic conditions of copper cations by ash of organic waste were constructed. The process of wastewater treatment of galvanic production is presented. It is concluded that the use of the adsorption method allows for a high degree of wastewater purification and its possible reuse for the technological needs of the enterprise.
