Abstract
Изобретение относитс к способам очистки воды от катионных поверхностно-активных веществ флотацией и может быть использовано при очистке сточных вод предпри тий химической, нефт ной, нефтеперерабатывающей промышленности, черной и цветной металлургии. Целью изобретени вл етс повышение степени очистки и сокращение объема флотационной пены. Дл осуществлени способа в раствор предварительно ввод т реагент-осадитель, в качестве которого используют гексаметафосфат натри (NAPO3)6, а образующийс осадок отдел ют флотацией. Способ позвол ет обеспечить 99,9%-ную очистку при меньшем расходе более дешевого реагента-осадител , причем объем флотационной пены не превышает 1-2% от объема раствора. 4 табл.The invention relates to methods for purifying water from cationic surfactants by flotation and can be used in the purification of wastewater from enterprises of the chemical, petroleum, petroleum refining industry, ferrous and nonferrous metallurgy. The aim of the invention is to increase the degree of purification and reduce the volume of flotation foam. In order to carry out the process, a precipitating reagent, which is sodium hexametaphosphate (NAPO 3 ) 6 , is used as a pre-reagent, and the precipitate formed is separated by flotation. The method allows for 99.9% purification with less consumption of a cheaper precipitating reagent, and the volume of flotation foam does not exceed 1-2% of the solution volume. 4 tab.

Изобретение относитс к способам очистки воды, в частно сти, от катион- ных поверхностно-активных веществ (солей алкйламмони и алкилпиридини , четвертичных аммониевых солей, а также технических препаратов - АНП-2, цетазола, катамина и др.) и может быть использовано на предпри ти х химической , нефт ной и нефтеперерабатывающей промышленности, черной и цветной металлургии.The invention relates to methods for purifying water, in particular, from cationic surfactants (alkylammonium and alkylpyridinium salts, quaternary ammonium salts, as well as technical preparations ANP-2, cetazol, catamine, etc.) and can be used for enterprises of the chemical, petroleum and petrochemical industries, ferrous and nonferrous metallurgy.
Кроме того, предлагаемый способ может быть использован дл очистки сточных вод предпри тий текстильного и лакокрасочного производства, а также бытовых сточных вод.. In addition, the proposed method can be used for wastewater treatment of textile and paint and varnish production enterprises, as well as household wastewater.
Цель изобретени - повышение степени очистки и сокращение объема флотационной пены. The purpose of the invention is to increase the degree of purification and reduce the volume of flotation foam.
Пример 1. В камеру флотационной машины помещают 1 л раствора,Example 1. In the chamber of the flotation machine is placed 1 l of solution,
содержащего 100 мг иодида цетилпири- дини (ЦПИ) и 100 мг гексаметафосфа- та натри , рН раствора 7. После 2 мин перемешивани раствор подвергают 15-минутной флотационной обработке и анализируют на содержание ЦПИ; Степень флотационного выделени (OQ coc- тавл ёт 99,9%.containing 100 mg of cetylpyridine iodide (CPI) and 100 mg of sodium hexametaphosphate, pH of solution 7. After stirring for 2 min, the solution is subjected to a 15-minute flotation treatment and analyzed for the CPI content; The degree of flotation discharge (OQ coc-tavl is 99.9%.
Пример 2. Услови аналогичны примеру 1 за исключением: концентраци хлорида пентадецилпиридини (ПДПХ) 100 мг/л, остаточна концентраци ПДПХ 0,05 мг/л, объем пены 1,0%.Example 2. The conditions are the same as in Example 1, except: the concentration of pentadecylpyridinium chloride (PDPH) is 100 mg / l, the residual concentration of PDPH is 0.05 mg / l, the foam volume is 1.0%.
ПримерЗ, Услови те же, за исключением: концентраци хлорида триметилоктадециламмони (ТМОДАХ) 100 мг/л, остаточна концентраци 0,07 мг/л, объем пены 0,5%.The sample conditions are the same, except for: the concentration of trimethyl octadecylammonium chloride (TMODAH) is 100 mg / l, the residual concentration is 0.07 mg / l, the volume of foam is 0.5%.
