Description
Summary:The authors suggest the complex technology of their treatment on the example of the specific industrial waste landfill. The technology involves industrial liquid waste treatment by stages. The solution of petroleum oil wastes being pumped from the pond at the landfill is supplied to the primary purification in the conventional oil separator which is combined with the settling pond. Additional treatment of water from oil products and suspended solids is carried out by a flotation unit. After the flotation unit for post-treatment of water from heavy metals, it is fed through a channel of trapezoidal cross-section to a filter dam being made of sorbent. The channel has been constructed in the earth water course. The subsoil is heavy loam and clay. The channel has a filter barrier, the design of which is constructed in the form of 2 metal frames being covered with wire nettings. There is a waterproofing layer made of polyvinyl chloride film at the bottom of the channel under the frames. A packing of fibrous sorbent is placed between the wire nettings to finally purify liquid wastes from petroleum residue, which allows treating discharge in accordance with the requirements of maximum permissible concentrations for fish-husbandry water utilization.
