(54) СПОСОБ ОЧИСТКИ СТОЧНЫХ ВОД ОТ ИСПОВ ТЯЖЕЛЫХ(54) METHOD FOR CLEANING WASTE WATER FROM ISPOV HEAVY

МЕТАЛЛОВMETALS

т оры арсената и фосфата кальци , нэ Которых мьшь к не переходит обратно в раствор как при отстаивании пульпы, так и при выщелачивании из -твердого остатка природными водами. При осаждении мьпиь ка предложенным способом медь, цинк, свинец, железо также захвап шаютс  осадком фосфата кальци  до содержани  их в очищаемой воде, соответствующего санитарным нормам, а именно, мг/л Со менее 0,1, Zn менее О,1, РЬ не обнаружено, Fe менее О,tors of arsenate and calcium phosphate, which I don’t go back to the solution both when settling the pulp and leaching from the solid residue with natural waters. During the deposition of the material by the proposed method, copper, zinc, lead, iron are also captured by calcium phosphate sediment until they are contained in the purified water that meets sanitary standards, namely, mg / l Co less than 0.1, Zn less than O, 1, Pb found to be less than o

Пример. Очистке подвергают раствор, содержа1ций следующие количества примесей, мг/л: As 12-100, РЬ 10, Си 10, ZM 50, Fe 25.Example. The solution is subjected to purification, containing the following amounts of impurities, mg / l: As 12-100, Pb 10, Cu 10, ZM 50, Fe 25.

К раствогу добавл ют 5-10%-ную вод ную суспензию гидроокиси кальци  с солью фосфата кальци  или Фосфорной кислотой.To the solution is added a 5-10% aqueous suspension of calcium hydroxide with a calcium phosphate salt or Phosphoric acid.

После интенсивного перемешивани  в течение 10-1Ь мин и получени  рН среды 11,5-12,0 пульпу отстаивают и раздел ют фазы. В фильтрате определ ют присутствие ионов т желых металлов Анализ показывает, что присутствие указанных ионов металлов соответствует предельно допустимым концентраци м .After vigorous stirring for 10-1b minutes and obtaining a pH of 11.5-12.0, the pulp is settled and the phases are separated. In the filtrate, the presence of heavy metal ions is determined. The analysis shows that the presence of these metal ions corresponds to the maximum allowable concentrations.
