The waste alkali liquor is mainly derived from the petrochemical production. It is a waste liquid with a large amount of pollutants formed by the absorption of NAOH solution, alkali washing oil and cracking gas. The alkalinity of the spent caustic is extremely high. If the reasonable pretreatment is not carried out, the high concentration of the spent caustic soda will enter the sewage biochemical treatment system, which will hinder the growth and reproduction of the microorganisms, and will cause serious consequences of the extinction of the microorganisms, and eventually interfere with the sewage. The normal operation of the treatment plant and the standard discharge of the total discharge of wastewater, so the treatment of contaminated soil from the factory waste alkali is a very important issue. This paper mainly studies the environmental geotechnical engineering control methods of polluted soil of factory waste lye. Based on the relationship between the equivalent elastic stress and the yield strength of contaminated soil, the ductile mechanical parameters of the contaminated soil of waste alkali liquor are calculated. On this basis, the clay particle analysis control model of the contaminated soil of waste alkali liquor is established to predict the soil contaminated by waste alkali liquor. The distribution of particles and pores is completed, and the detection of contaminated soil of waste alkali liquor in geotechnical engineering is completed. The solidification agent (cement) and sodium persulfate are added to the contaminated soil of waste alkali liquor to realize the purification treatment of contaminated soil of waste alkali liquor. The experimental results show that the benzene content in each soil layer after purification treatment is larger, and the benzene content after purification is below 4.3mg/kg, and the soil layer pollution is treated by CPS method and tandem mass spectrometry. Although the benzene content in the soil decreased, the benzene content was still higher than the larger specific gravity after purification. The simulation results in this paper show that the curing agent (cement) can promote the treatment of benzene and 1,4-dichlorobenzene in the contaminated soil of waste alkali liquor by sodium persulfate purification, and the proposed method can purify and treat the waste soil in different depths of the surface. The ability of benzene and 1,4-dichlorobenzene is better than the comparison method, and it is a method for purifying contaminated soil of waste alkali liquor in rock engineering with high purification degree.
