Abstract
Спосіб очищення стічних вод від іонів хрому (VI) концентрацією до 1 г/дм3, згідно з яким у стічні води вводять сіль заліза (II) до утворення співвідношення іонів Fe2+ і Cr6+ 10:1, розчин лугу до досягнення величини рН 10,5 та барботують повітрям (аерують) при об'ємній витраті повітря 2 дм3/хв/1 дм3 протягом 15 хв, причому процес відбувається у змінному магнітному полі силою 0,1 Тл замість нагрівання при 60-90 °C.The method of purifying wastewater from chromium (VI) ions with a concentration of up to 1 g/dm3, according to which an iron (II) salt is introduced into the wastewater until the ratio of Fe2+ and Cr6+ ions is 10:1, an alkali solution is introduced until the pH value is 10.5, and bubble with air (aerate) at a volumetric air flow rate of 2 dm3/min/1 dm3 for 15 min, and the process takes place in an alternating magnetic field with a force of 0.1 T instead of heating at 60-90°C.
