Example Embodiment
[0049] Example 1:
[0050] This embodiment provides a rapid and harmless biodegradation method for waxy oil sludge, and the method includes the following steps:
[0051] Step one, prepare seed liquid:
[0052] Pseudomonas aeruginosa NY3 in this application is an existing strain, see literature: Maiqian Nie, Xihou Yin, Chunyan Ren, Yang Wang, Feng Xu, Qirong Shen. Novel rhamnolipid biosurfactants produced by a polycyclic aromatic hydrocarbon-degrading bacterium Pseudomonas aeruginosa strain NY3.Biotechnology Advances.,2010,28:635–643.
[0053] Pseudomonas stutzeri N2 is an existing strain, see literature: Fan Yu, Nie Maiqian, Ge Bizhou, Wanyi, Zi Jing, Zhao Jing, Shen Xiaojuan, Chen Xingdu. High-concentration phenol-resistant strains Screening and its degradation characteristics. Journal of Environment and Safety. 2012,12(4):113-117.

Example Embodiment
[0088] Example 2: Changing the particle size of wood chips
[0089] The difference between this comparative example and Example 1 is only that the particle size of the sawdust has the original 0.3mm, replaced by 0.56mm and 1mm respectively. The other process is the same as that of Example 1. It is cultured on a shaker at a constant temperature and aerobic at 30°C. 6d, complete the degradation of waxy oil sludge.
[0090] The degradation result is: the degradation result of linear normal alkane is shown in image 3 , The degradation rate of each straight-chain n-alkane in petroleum hydrocarbons is significantly lower than that in Example 1 when the particle size of wood chips is 0.3 mm, and the degradation rate of phenanthrene and pyrene is also lower.
Example Embodiment
[0091] Example 3:
[0092] This example is the same as the other processes of example 1, except that in the biodegradation process of step 4, 7 ml of Pseudomonas aeruginosa NY3 seed liquid prepared in step 1 is added to the degradation system obtained in step 3, and Shi’s false 3ml of the monosporium N2 seed solution was cultured on a shaker at a constant temperature and aerobic at 30°C for 6 days to complete the degradation of waxy oil sludge.
[0093] Result test characterization:
[0094] The removal rate of C14~C18 in waxy oil sludge is above 80%, the removal rate of C19~C30 is between 70% and 83%, and the removal rate of C31~C38 is between 53% and 66%. The removal of phenanthrene and pyrene The rates can reach 30.9% and 28.1% respectively.
[0095] The output of conversion products in waxy oil sludge is 0.23g conversion products per gram of waxy oil sludge, and the characterization results are the same as those in Example 1, which proves that the conversion products contain glyc...
