Abstract
Research results of sewage treatment of zinc production from ions of heavy non-ferrous metals with use of lime milk, sodium sulphide, flocculants are resulted. It is shown: independent clearing by lime milk does not allow to provide the concentrate of heavy non-ferrous metals according to requirements as fisheries (zinc < 0.1 mg/l), and generaluse (zinc < 1mg/l); sharing of lime milk and flocculant allows to provide the zinc concentrate in drains to level of requirements of general-use; application of sulphide of sodium at last stage of clearing and as a fine filtration of drains gives the chance to receive the drains corresponding to requirements of reservoirs of fisheries use.
