The given article discusses the problem of purification of oil wastewater. It provides the information of pollution of oil wastewater which is produced by the food enterprise, and also the ways of its purification.. The most effective way to dispose dissolved and digestible fractions of oil products is biological wastewater purification. The process of oil wastewater purification by airtank-mixer has been researched. The intensification of the process of purification by the block of biochemical oxidation has been conducted, which includes the apparatus with foam layers and an airtank-clarifier. The scientific novelty of the research lies in biosorbtion of oil gas-liquid countercurrent mode and oxidation in an airtankclarifier.
