遼河河口區(qū)濕地水體中石油類(lèi)污染物凈化能力優(yōu)化與仿真
[Abstract]:By using the method of field investigation and systematic simulation, taking the wetland in Shuguang area of Liaohe Oilfield as the research object, the present situation of oil pollution and purification ability of wetland water body in the study area is comprehensively analyzed. Based on Monte Carlo simulation, a model for estimating the purification efficiency of petroleum pollutants in wetlands is proposed. According to the natural characteristics of the study area, the purification capacity of different areas of the wetland is optimized and designed by using the factors of water quantity and nitrogen and phosphorus nutrition and so on. The results show that there are differences in the purification capacity of petroleum pollutants among the blocks, mainly due to the different structure and inherent characteristics of wetlands between blocks. The purification efficiency of petroleum pollutants in wetland is 5.4mg / L ~ (-1) and the average residual concentration is 1.05 mg / L ~ (-1). Through the optimization design, the purification efficiency of petroleum pollutants is about 20%. The optimization design and simulation control method of wetland purification capacity established in this paper provide an important technical means for removing petroleum pollutants in the wetland water body of Liaohe estuary.
