Abstract
1. Способ очистки сточных вод титано-магниевого производства, включающий смешивание промышленных стоков, отделение из них твердых взвесей в песколовке, перемешивание, нейтрализацию известковым молоком, обработку флокулянтом типа Праестол в виде водного раствора, отстаивание, разделение на очищенные стоки и шлам, обработку шлама флокулянтом типа Праестол в виде водного раствора и его разделение центрифугированием на фильтрат и твердый осадок, отличающийся тем, что стоки нейтрализуют известковым молоком в две стадии: первоначально после отделения твердых взвесей в движущийся поток стоков подают известковое молоко при объемном расходе известкового молока, равным 5-20 м/ч, перемешивают в течение 1,0-1,5 ч и затем на стадии нейтрализации стоки обрабатывают известковым молоком при объемном расходе, равным 0,1-5,0 м/ч, а шлам со стадии отстаивания смешивают со шламом со стадии нейтрализации и со шламом со стадии обработки флокулянтом типа Праестол, перемешивают и полученную смесь обрабатывают флокулянтом типа Праестол в виде водного раствора при массовой концентрации флокулянта, равной, мас.%: 0,5-0,8, и при соотношении шлам: флокулянт типа Праестол, равным (10-20):1.2. Способ по п.1, отличающийся тем, что концентрация оксида кальция в известковом молоке составляет не менее 100 г/дм.3. Способ по п.1, отличающийся тем, что стоки перемешивают одновременно с помощью механической мешалки и барботером.4. Способ по п.1, отличающийся тем, что стоки обрабатывают флокулянтом типа Праестол при соотношении флокулянт:стоки, равным 1:(95-110).5. Способ по п.1, отличающийся тем, что флокулянт типа Праестол подают в стоки при скорости подачи, равной 2,2-6 м/ч.61. A method for wastewater treatment of titanium-magnesium production, including mixing industrial effluents, separating them from solid suspensions in a sand trap, mixing, neutralizing with milk of lime, treatment with a Praestol flocculant in the form of an aqueous solution, settling, separation into treated effluents and sludge, processing sludge flocculant of the Praestol type in the form of an aqueous solution and its separation by centrifugation into a filtrate and a solid precipitate, characterized in that the effluents are neutralized with milk of lime in two stages: initially after separating solid suspensions into the moving effluent stream, milk of lime is fed at a volume flow of milk of lime equal to 5-20 m / h, stirred for 1.0-1.5 hours and then, at the stage of neutralization, the sewage is treated with lime milk at a volume flow of 0 , 1-5.0 m / h, and the sludge from the sedimentation stage is mixed with the sludge from the neutralization stage and with the sludge from the Praestol type flocculant treatment stage, mixed and the resulting mixture is treated with the Praestol type flocculant in the form of an aqueous solution at a mass concentration of flocculant, p . Implicit, in weight%: 0.5-0.8, and at a ratio of slime: type flocculant Praestol equal to (10-20): 1.2. The method according to claim 1, characterized in that the concentration of calcium oxide in the milk of lime is at least 100 g / dm. The method according to claim 1, characterized in that the drains are mixed simultaneously using a mechanical stirrer and a bubbler. The method according to claim 1, characterized in that the effluent is treated with a Praestol-type flocculant with a flocculant: effluent ratio of 1: (95-110). The method according to claim 1, characterized in that the Praestol-type flocculant is fed into drains at a feed rate of 2.2-6 m / h.
