Embodiment 1

[0022] Example 1 Nano bamboo charcoal promotes the biodegradation of polycyclic aromatic hydrocarbon phenanthrene

experiment example 1

[0023] Experimental example 1: Take a certain amount of phenanthrene in cyclohexane solution, which contains 3mg of phenanthrene, and place it in a sterilized Erlenmeyer flask. After the cyclohexane has evaporated, add sterile inorganic salt culture solution, and then add 6mg Nano bamboo charcoal, and then inoculate the GY2B bacteria solution stored in the refrigerator, add inorganic salt culture solution to 30ml, and the initial bacteria concentration in the culture solution after configuration is 8×10 6 The concentration of nano bamboo charcoal is 200mg / L and the concentration of phenanthrene is 100mg / L. Placed in a vibrating incubator with a temperature of 30℃ and 150r / min for 2 days. Regular samples are taken to determine the residual amount of phenanthrene. Parallel experiments, take the average of the results of the parallel experiments, the results are as figure 1 Shown.

Abstract

The invention relates to a method for degrading a petroleum component by utilizing nano bamboo charcoal reinforcing functional microorganism and application of the method. The functional microorganism is sphingomonas sp. GY2B; the petroleum component includes polycyclic aromatic hydrocarbon (phenanthrene) and crude oil; 50 to 200mg / L of nano bamboo charcoal can be added to obviously improve the degrading capacity of the functional strain GY2B on petroleum component in water; the sodium alginate embedding method is adopted to cure nano bamboo charcoal and the functional microorganism GY2B to be applied to biological treatment of wastewater containing petroleum component and biological repair of water polluted by petroleum.

Description

Technical field [0001] The invention belongs to the technical field of biological treatment and bioremediation of environmental organic matter pollution, and specifically relates to a degradation liquid for degrading petroleum components and a method for degrading petroleum components. Background technique [0002] Oil pollution is an important energy and industrial raw material indispensable in human production and life. With the development of the petroleum industry and the development of the port oil transportation industry, the probability of oil spills is increasing. According to data released by the China Maritime Safety Administration in 2007, there is an oil spill accident from a ship every three days in my country. If oil pollution incidents occur so frequently and intensively, if a rapid and timely response is not taken, the problem of oil pollution in water bodies will become increasingly prominent. The marine ecological environment and human health pose a serious thre...
