摘要
国外地下水监测用采样设备大致分为4类:取样筒式采样器、惯性式采样器、气体驱动式采样器和潜水电泵式采样器。取样筒式采样器原理简单、制作方便、成本低,受监测井井径、采样深度影响较小;惯性式采样器外径小,可应用于小口径地下水监测井,采样深度可达到90 m;气体驱动式采样器结构较复杂,适用范围广,适用于大部分地下水监测井,采样效率较高。潜水电泵式采样器采样效率很高,适应井径较大。
The sampling equipment for groundwater monitoring is divided into bucket sampler, inertial sampler, gas-driven sampler and the submersible pump sampler in foreign countries.The bucket sampler has the features of simple technical principle, easy-making, low cost and wide application range and is less affected by the monitoring well diameter and the sampling depth;the inertial sampler has small diameter and can be used in small diameter monitoring well with sampling depth up to 90m; the gas-driven sampler has complex structure and wide application range, which is suitable for most groundwater monitoring wells with high efficiency;the submersible pump sampler is the most effective one in these four.
