基于包气带动力学的长白山天然矿泉水水源地土壤吸附能力研究

为了提高水源地包气带土壤的吸附能力，提出基于包气带动力学的长白山天然矿泉水水源地的土壤吸附能力研究方法。根据长白山地区的地质概况，发现水源地包气带可以吸附和净化污染物，以长白山天然矿泉水水源地包气带为研究对象，将其划分为东郊、南郊和北郊3个水源地包气带。结合动力学实验，测试了3个水源地包气带对苯酚和柴油的吸附能力。结果表明，3个长白山天然矿泉水水源地包气带对苯酚的吸附速率分别为19.145 5、21.554 5、19.695 5 mg/（kg·h），对柴油的吸附速率分别为1.734 725、2.282 9、2.995 925 mg/（kg·min），说明白山天然矿泉水水源地包气带土壤对苯酚和柴油的吸附能力较强，可以提高长白山天然矿泉水水源地的土壤吸附能力。

Study on soil adsorption capacity of natural mineral water source in Changbai Mountain based on aeration zone dynamics

In order to improve the adsorption capacity of soil in the vadose zone of water source，a research method of soil adsorption capacity of natural mineral water source in Changbai Mountain based on the dynamics of vadose zone was proposed.According to the geological situation of Changbai Mountain area，it was found that the vadose zone of water source could adsorb and purify pollutants.Taking Changbai Mountain natural mineral water source vadose zone as the research object，it was divided into the vadose zone of eastern suburbs water source and the vadose zone of southern suburbs water source.The air belt and the vadose belt of the water source in the northern suburbs.Combined with kinetic experiments，the adsorption capacity of phenol and diesel in the vadose zone of three water sources was tested.The results showed that the adsorption rates of phenol in the vadose zone of the three Changbai Mountain natural mineral water sources were 19.145 5，21.554 5 and 19.695 5 mg/（kg·〗h），respectively.The adsorption rates of diesel oil were 1.734 725，2.282 9 and 2.995 925 mg/（kg·min），respectively，indicating that the vadose soil of the natural mineral water source of Baishan Mountain had phenol and Diesel has a strong adsorption capacity，which could improve the soil adsorption capacity of the natural mineral water source of Changbai Mountain.
