Abstract

Изобретение относитс  к способам получени  сорбента дл  очистки сточных вод от органических веществ и может быть использовано в обогатительных производствах дл  очистки от флотореагента АНП-2. Целью изобретени   вл етс  повышение емкости сорбента. Дл  осуществлени  способа золу обрабатывают раствором плава хлоридов, а затем дополнительного раствором гексаметилентетрамина при массовом соотношении золы и гексаметилентетрамина, равном 1:0,5. Способ позвол ет повысить емкость сорбена по флотореагенту АНП-2 на 60% и сократить расход сорбента в 1,6 раза. 1 з.п. ф-лы, 1 табл.The invention relates to methods for the preparation of a sorbent for the purification of wastewater from organic matter and can be used in enrichment plants for the purification of the ANP-2 flotation reagent. The aim of the invention is to increase the capacity of the sorbent. To carry out the process, the ash is treated with a solution of floating chlorides, and then with an additional solution of hexamethylenetetramine with a weight ratio of ash and hexamethylenetetramine equal to 1: 0.5. The method allows to increase the capacity of the sorben in the flotation reagent ANP-2 by 60% and reduce the consumption of the sorbent 1.6 times. 1 hp f-ly, 1 tab.

Description

Изобретение относитс  к способам получени  сорбента дл  адсорбционной очистки сточных вод от органических веществ   может быть использовано при очистке сточных вод обогатительных фабрик от флотоагрегата АНП-2.The invention relates to methods for obtaining a sorbent for adsorption purification of wastewater from organic substances that can be used in the treatment of wastewater treatment plants from the flotation unit ANP-2.

Целью изобретени   вл етс  повышение емкости адсорбента, в отношении флотореагента АНП-2.The aim of the invention is to increase the capacity of the adsorbent, in relation to the flotation agent ANP-2.

Пример. Навеску мелкодисперсной золы от сжигани  бурых углей массой 1 г обрабатывают 5-10%-ным раствором хлоридного плава в течениеExample. A portion of fine ash from the combustion of brown coal weighing 1 g is treated with a 5-10% solution of chloride melt during

2 ч,затем в течение 20-30 мин - раствором гексаметилентетрамина (ГМТА) при соотношении зола : ГМТА 1:0,5. Через обработанную золу пропускают сточные воды обогатительной еЬабрики с содержанием флотореагента АНП-2 10 мг/л до тех пор, пока степень очистки не упадет ниже 90% емкости до проскока. Одновременно определ ют количество чоды до проскока и емкость золы по известному способу,.2 h, then for 20-30 min - with a solution of hexamethylenetetramine (HMTA) with an ash: HMTA ratio of 1: 0.5. The treated ash is treated with wastewater from the enrichment plant with a flotation reagent of ANP-2 10 mg / l until the purification rate drops below 90% of the capacity before the breakthrough. At the same time, the amount of the chody before breakthrough and the ash capacity are determined by a known method.
