Abstract

​

Waste processing of oil refineries and petrochemical industries is currently one of the pressing environmental problems in Russia. One of the most dangerous pollutants of almost all components of the natural environment are oily waste - oil sludge. At present, fundamentally new technical solutions are being developed for the remediation of sludge storage ponds and the processes of obtaining chemical products as a result of the utilization of waste accumulated in them. According to the research results, a method of remediation of sludge storage ponds, which is a two-stage process, has been developed. At the first stage, biological decomposition of oil waste is carried out using microorganisms, which allows to solve the problem of their subsequent disposal. At the second stage, the fertility of disturbed lands is restored by phytoremediation. The method consists in planting herbaceous vegetation and tree seedlings over the entire area of recultivated land. The implementation of this method of remediation of sludge ponds will reduce the cost of services to third-party companies for the disposal of oil sludge.

Key words:

​

oil sludge, sludge pond, bioremediation, phytoremediation, remediation of oil-contaminated lands, biological remediation.
