Soil environment monitoring system

Abstract

The invention provides a soil environment monitoring system. The soil environment monitoring system comprises a measuring platform, a support component, a soil analyzing component, an electric controlbox, a gas chromatography measuring component and a sampling component, wherein the support component is arranged under the measuring platform; the soil analyzing component is arranged under the front end of the measuring platform and is connected with the support component through a fixing frame; the electric control box is arranged above the front end of the measuring platform and is connectedwith the soil analyzing component and the gas chromatography measuring component; the gas chromatography measuring component is arranged above the rear end of the measuring platform; the sampling component is vertically arranged on the measuring platform, passes through the measuring platform and is located between the electric control box and the gas chromatography measuring component. The soil environment monitoring system can be directly moved to the soil position of the measuring site, is capable of sampling and measuring the soil in different depths, mixing water with the soil after sampling, then heating, more fully volatilizing the gas, effectively improving the operation efficiency, improving the measurement accuracy and reducing the labor cost.

Description

technical field [0001] The invention relates to a soil monitoring technology, in particular to a detection system for measuring pollutants in soil and soil components. Background technique [0002] Soil refers to the loose surface layer on the land surface that is fertile and capable of growing plants, and its thickness is generally about 2m. Soil not only provides mechanical support for plant growth, but also provides fertility elements such as water, fertilizer, air, and heat for plant growth and development. Due to the rapid growth of population and the rapid development of industry, solid wastes are continuously stacked and dumped on the soil surface, harmful waste water is continuously infiltrated into the soil, and harmful gases and floating dust in the atmosphere are also continuously falling into the soil with rainwater, resulting in soil pollution. All substances that hinder the normal function of the soil, reduce the yield and quality of crops, and indirectly affe...

Problems solved by technology

Soil testing needs to select the collection point in advance, mark the collection point, and then manually take an appropriate amount of soil and send it to the testing center for testing. The soil testing cycle is long, the workload is heavy, the labor cost is high, and the soil testing efficiency is low.

[0004] The soil composition monitoring uses a soil analyzer, and the monitoring of soil quality pollutants requires the use of a gas chromatograph. The gas chromatograph needs to heat the soil after use, and the evaporated gas after heating is absorbed by the gas chromatograph to measure the results; the gas chromatograph When using, there are currently several problems: on the one hand, the heater heats the bottom, which makes the inside of the box high temperature. Volatilization, in order to avoid inaccurate monitoring caused by incomplete volatilization of the soil, in the existing technology, extrusion is often used to speed up the gas discharge rate and achieve a more thorough gas discharge, which is cumbersome and inefficient

However, the structure provided by this invention can only monitor the basic information of the soil such as humidity, pH and other information in real time through sensors, and it is difficult to monitor the soil composition and the content of pollutants in the soil.
