METHOD FOR CLEANING OF PETROLEUM-CONTAMINATED RAG AND PROCESS FABRIC

摘要

FIELD: biotechnology, in particular ecology. ^ SUBSTANCE: method for cleaning of rag and process fabric contaminated with petroleum and petroleum products includes ultrasonic treatment of said rag or fabric in water medium. Then formed water-and-oil emulsion and partially cleaned fabric are separated and separately fermented by using biopreparation based on bacterium strain Acinetobacter sp.(biococcum) under intense aeration. As nitrogen, phosphorus and potassium sources mineral fertilizers are used. Claimed method makes it possible to fully clean contaminated fabrics which may by repeatedly used or reprocessed as secondary raw materials. ^ EFFECT: improved and environmentally friendly method for cleaning of rag and process fabric contaminated with petroleum and petroleum products. ^ 3 ex
