Product introduction: The company cooperates with Tianjin Institute of industrial biotechnology, Chinese Academy of Sciences, to develop bio cleaning degradation technology (hereinafter referred to as BCD) based on the unique function of microbial metabolism of petroleum hydrocarbons. This technology is used to treat all kinds of oily sludge and the ecological restoration of oil contaminated soil. Aiming at the high oily sludge, the thermophilic bacteria is used for biological cleaning, which has the advantages of low cost, high efficiency, low energy consumption and no pollution. The technology can not only effectively treat oil sludge, but also recover part of oil resources, and further use petroleum hydrocarbon degradation bacteria to carry out deep treatment of low oil sludge, so as to achieve the standard discharge.
