FIELD: wastewater complex treatment.
SUBSTANCE: invention relates to the complex treatment of wastewater containing petroleum products, oils, surfactants, heavy metals, and can be used to treat wastewater from enterprises in various industries to a quality corresponding to the maximum permissible concentrations of pollutants for discharge into fishery water bodies. The method includes filtration of wastewater through a layer of modified hydrolytic lignin SynergySorb® PS-1000 1.5-2.4 m high, additional filtration through a layer of granulated brucite 0.6-1.2 m high located in front of the layer of modified hydrolytic lignin. The filtration rate is 4-8 m/h. The sorption layers are regenerated at least after every seventh filter cycle.
EFFECT: purification of wastewater to regulatory requirements is provided by a simplified technology, with an increased time of effective operation of the used sorbents.
