Abstract
1. Способ очистки сточных вод от ионов кальция, включающий ввод кальцинированной соды, щелочи до оптимальных значений рН, железного купороса, отличающийся тем, что в подготавливаемую воду вводится анионное поверхностно-активное вещество, например мыло сырого талового масла, а затем коагулянт, например железный купорос, с доводкой значений рН до 11,0-11,5. ! 2. Способ по п.1, отличающийся тем, что для интенсификации флокулообразования и увеличения скорости осаждения концентрация анионных поверхностно-активных веществ составляет 20-70 мг/л. ! 3. Способ по п.1, отличающийся тем, что для удаления образованных флокул флотацией концентрация анионных поверхностно-активных веществ составляет 50-100 мг/л. 1. The method of purification of wastewater from calcium ions, including the input of soda ash, alkali to optimal pH values, vitriol, characterized in that anionic surfactant, for example soap of crude tall oil, and then a coagulant, for example iron, are introduced into the prepared water vitriol, with adjusting the pH to 11.0-11.5. ! 2. The method according to claim 1, characterized in that for the intensification of flocculation and increase the deposition rate, the concentration of anionic surfactants is 20-70 mg / L. ! 3. The method according to claim 1, characterized in that to remove the flocs formed by flotation, the concentration of anionic surfactants is 50-100 mg / L.
