Wastewater treatment using heat-treated defectate and MAP solution
Abstract
Abstract This article presents the results of quantitative and qualitative characteristics of wastewater from the tailing pond of the Navoi Mining and Metallurgical Combine. Pollutants coming from the processing of ores were determined. The studied effluents had high concentrations of dissolved salts and suspended solids. Laboratory tests were carried out for wastewater treatment using samples of thermally processed defecate and MAP solution. It has been shown that thermal processed defecation and monoammonium phosphate (MAP) solution are effective for wastewater treatment from polluting ions. The consumption of thermally processed defecation was 10 g/l and 25% MAP was 15 ml/l, while the degree of reduction of the elements Ca, Mg, K, Be, AI, Mn, Ni, Cu, Zn, As, Se, Sr, Mo, Pb was 87.82, 90.64, 70.72, 96.35. 92.64, 99.79, 63.69,18.95, 91.12, 98.38, 70.85, 78.56%.
