Description

д т при Катодной плотности тока 5- 50 мА/см 2. Очищенна  вода имеет ХПК 9,5гОг/л, ВПК 1,5 г 02/л, НЭЖ 2 г/л при рН 6,15..dt at a cathode current density of 5-50 mA / cm2. Purified water has a COD of 9.5 gOg / l, MIC 1.5 g of 02 / l, NEJ 2 g / l at pH 6.15 ..

Объем образовавшегос  флотоконденсата составл ет 12,5°/о от объема обрабатываемой воды, влажность 92%.The volume of float-condensate formed is 12.5 ° / o of the volume of treated water, the humidity is 92%.

Пример 2. Шерстомойные сточные воды с такой же характеристикой, как в примере 1, обрабатывают с добавлением 3 г/л хлористого кальци  и 40 мг/л полиакриламида. Электрофлотацию осуществл ют при той же плотности тока.Example 2. Wool washing waste water with the same characteristic as in example 1 is treated with the addition of 3 g / l of calcium chloride and 40 mg / l of polyacrylamide. Electroflotation is carried out at the same current density.

Очищенна  вода имеет ХПК 9,4гОг/л, БПКв 1,5гОг/л, НЭЖ 1,9 г/л при рН 8,00.The purified water has a COD of 9.4 gOg / l, BOD in 1.5gOg / l, NEL, 1.9 g / l at pH 8.00.

Объем образовавшегос  флотоконденсата составл ет 2,5% от объема обрабатываемой водь1, влажность 81%.The volume of the formed flotation condensate is 2.5% of the volume of water treated, and the humidity is 81%.

По сравнению с известными предлагаемый способ позвол ет в 5-10 раз сократить объем флотоконденсата и снизить его влажность до 75-81%, что позвол ет уменьшить объем сооружений по обработке осадка и сократить капитальные и эксплуатационные затраты при очистке сточных вод шерстомойного производства.Compared with the known methods, the proposed method allows reducing the volume of flotation condensate by a factor of 5-10 and reducing its humidity to 75-81%, which allows reducing the volume of sludge treatment facilities and reducing capital and operating costs for wastewater treatment of wool-washing production.
