背景技术Background technique
随着工业转型和城市扩张进程的加快，城市周边区域的工业企业搬迁、停产或倒闭，而部分企业所遗留的原址场地受到生产过程中“跑、冒、滴、漏”以及工业“三废”排放的影响，导致场地土壤受到了不同程度的污染，而酸碱污染土壤较为普遍且污染方量较大，若未进行治理修复，酸碱土壤会影响动植物生长、污染水体、腐蚀构建筑等，危害人体健康和影响人居环境。With the acceleration of industrial transformation and urban expansion, industrial enterprises in the surrounding areas of the city have relocated, stopped production or closed down, and the original sites left by some enterprises have been affected by the "running, running, dripping, and leaking" in the production process and the discharge of industrial "three wastes". The soil of the site has been polluted to varying degrees due to the impact of environmental pollution, and acid-base polluted soil is more common and has a large amount of pollution. If it is not treated and repaired, acid-base soil will affect the growth of animals and plants, pollute water bodies, and corrode structures. Harm to human health and affect the living environment.
传统的酸碱污染土壤一般采用粗放的处置方式，即在场地内修建一定大小的基坑，将酸碱污染土壤清挖转运至处置基坑中，加入大量的水及适量药剂，利用挖掘机进行拌和并检测，直到修复合格后转运至养护区。但由于酸碱污染土壤本身的均质性较差，在使用药剂中和过程中难度较大，易造成二次污染，另外由于酸碱指标的敏感性较强，在加药过程中由于搅拌不均匀或药剂配制浓度偏差不易达到修复目标值。Traditional acid-base contaminated soil generally adopts extensive disposal methods, that is, a foundation pit of a certain size is built on the site, the acid-base contaminated soil is excavated and transported to the disposal foundation pit, a large amount of water and appropriate amount of chemicals are added, and excavators are used to carry out the treatment. Stir and test, and transfer to the conservation area until the repair is qualified. However, due to the poor homogeneity of the acid-base polluted soil itself, it is difficult to neutralize the process of using chemicals, which is easy to cause secondary pollution. It is not easy to achieve the repair target value evenly or with concentration deviation of medicament preparation.
