Description

1
Изобретение относитс  к области очистки сточных вод производств цветной металлургии и химической промышленности.
Известный способ очистки сточных вод от иоцов т желых металлов заключаетс  в их адсорбции на углеродсодержащих материалах , например активированном угле.
Недостатком известного способа  вл етс  степень очистки, остаточна  концентраци  т желых металлов, например ртути, составл ет 0,1-0,2 мг/л.
Предложенный способ отличаетс  от известного тем, что углеродсодержащий материал предварительно пропитывают серусодержащим органическим соединением, например, меркаптанам алифатического р да с длиной цепи Ci-Cs, алкинилмеркаптаном состава Cz-€5 или моноцикличеоким меркаптаном ароматического р да, а количество серусодержащего соединени  составл ет 0,5-10% от веса примен емого адсорбента.
Эти отличи  позвол ют повысить степень ОЧИСТКИ: концентраци  ртути составл ет 0,02 мг/л или ниже.
Пример 1. Активированный уголь прочитывают этилмеркаптаном в количестве 0,5% от веса угл  и выдерживают в течение суток .
После суточной выдержки 50 кг обработанного адсорбента загружают в адсорбционную
колонку. Через колонку пропускают сточную воду, содержащую 0,1-3 мг/л ртути в количестве 300 м.
В очищенно сточной воде остаточное содержание ртути составл ет 0,015 мг/л.
Пример 2. 50 кг активированного угл  пропитывают 250 г этилмеркаптана. Пропитку ведут в течение 24 час.
Пропитанный этилмеркаптаном адсорбент загружают в адсорбционную колонку и пропускают сточную воду, содержащую соединени  ртути. Остаточное содержание ртути составл ет 0,005-0,02 мг/л.
Предмет изобретени 

Claims (2)

1.Способ очистки водных растворов от ионов т желых металлов, на пример ртути, путем их адсорбции углеродсодержащим материалом , отличающийс  тем, что, с целью повышени  степени очистки, углеродсодержащий материал предварительно пропитывают серусодержащим органическим соединением, например меркацтаном алифатического р да с длиной цепи Ci-€5, алкинилмеркаптаном состава €2-СБ или моноциклическим мер:каптаном ароматического р да.
2.Способ по п. 1, отличающийс  тем, что количество серусодержащего соединени  составл ет 0,5-10% от веса примен емого утлеродсодержащего адсорбента.
