Increasing overburden pressure is a key factor that alters the chemical and physical properties of soils and sediments. However, limited information is presently available on how aquifer compression impacts water quality. We introduced a novel compaction device, which is composited of four parts, including pressure simulator reactor system (PSRS), gas-liquid separator (GLS), automatic collector (AC) and composite control system (CCS). We conducted experiments at various pressures to test the functionality and outcomes of the device. In general, this device can be used to examine changes in water chemistry associated with aquifer compression resulting from compaction (overburden pressure) or groundwater overdraft.

上覆压力的增加是改变土壤和沉积物化学和物理性质的关键因素。但是，目前关于含水层压缩如何影响水质的信息有限。我们介绍了一种新颖的压实设备，该设备由四个部分组成，包括压力模拟器反应器系统（PSRS），气液分离器（GLS），自动收集器（AC）和复合控制系统（CCS）。我们在各种压力下进行了实验，以测试设备的功能和结果。通常，该设备可用于检查与压实（上覆压力）或地下水透支导致的含水层压缩有关的水化学变化。
