Claims (2)

1. Способ утилизации осадков сточных вод, содержащих смеси гидроксидов и/или гидроксикарбонатов тяжелых металлов, включающий использование указанных осадков в качестве добавок к природным видам сырья для производства бетонных изделий, отличающийся тем, что к заданным количествам природных известняка и глины с известным содержанием алюминия и железа добавляют рассчитанное количество осадка сточных вод с эквивалентным содержанием алюминия, железа и хрома и тщательно перемешивают, затем приготовленную сырьевую смесь обжигают при 1450 - 1500oС до остаточного содержания несвязанного оксида кальция не более 0,5 мас.%, а полученный монолитный продукт обжига (цементный клинкер) охлаждают и измельчают в тонкодисперсный порошок, который используют для изготовления бетонный изделий известными способами.1. The method of disposal of sewage sludge containing mixtures of hydroxides and / or hydroxycarbonates of heavy metals, including the use of these sludges as additives to natural types of raw materials for the production of concrete products, characterized in that to a given amount of natural limestone and clay with a known aluminum content and iron add the calculated amount of sewage sludge with an equivalent content of aluminum, iron and chromium and mix thoroughly, then the prepared raw material mixture is fired at 1450 - 1500 o C to a residual content of unbound calcium oxide of not more than 0.5 wt.%, and the obtained monolithic firing product (cement clinker) is cooled and ground into a fine powder, which is used for the manufacture of concrete products by known methods. 2. Способ по п.1, отличающийся тем, что осадок сточных вод с известным содержанием алюминия, железа и хрома добавляют к смеси природных известняка и глины взамен 5 - 35 мас.% глины с эквивалентным содержанием алюминия и железа. 2. The method according to claim 1, characterized in that the sewage sludge with a known content of aluminum, iron and chromium is added to a mixture of natural limestone and clay instead of 5 to 35 wt.% Clay with an equivalent content of aluminum and iron.
