Description
Technical field
The present invention relates to pollutant monitoring system in a kind of phreatic water, belong to environmental science, underground water pollution and soil
Earth research field.
Background technology
Along with the development of agricultural modernization, a large amount of uses of fertilizer and pesticide become Soil Environmental Pollution main because of
Element.Water environment is caused and has a strong impact on by its Pesticide Residues.Research finds, the consumption of water soluble pesticide accounts for the total consumption of pesticide
More than 50%, it is dissolved in after applying rice field in paddy field water, easily the contaminant water environment by rainwash, soil percolation more.Shen Genxiang
Deng rice field loss characteristic and influence factor thereof by studying water soluble pesticide, draw Cupric sulfate and the rice field of two kinds of pesticide of Rogor
Total number of dropouts accounts for the 14.3% and 13.3% of total consumption respectively.Subsoil water water temperature is relatively low, and content of microorganisms is few and active weak, does not has
Sunlight direct irradiation, after the Pesticide Infiltration of using in farmland enters soil subterranean layer, its degradation speed is slower than surface water.Subsoil water
Once by pollution by pesticides, not only refractory reason, recover required time long, even cannot recover, thus the pollution that pesticide is to subsoil water
Problem enjoys Chinese scholars to pay attention to, for one of the focus in international environmental studies field.The countries such as America and Europe extensively carry out pesticide pair
Polluting and the investigation of residual situation of subsoil water, the U.S. carries out national to underground water pollution of pesticide as far back as the eighties in last century
Census operations, finds that the Pesticides Residues of subsoil water is fairly common, and the most only tens kinds of pesticide are detected, and indivedual pesticide
Residual concentration exceeds standard more than 100 times.At present pesticide residual in subsoil water has been listed in the conventional sense item of water quality by many countries
Mesh, the data etc. in terms of must provide for during agriculture chemical registration about underground water pollution probability.In China, pesticide is to underground water pollution
Problem not yet has systematic study and detection, but, the pollution of subsoil water is happened occasionally by pesticide, such as Tianmen county, Hubei (1996) once
Because cotton region uses pesticide seepage to cause drinking water contaminated, parathion pesticide concentration reaches 1.125mg/L (exceeding standard 375 times), and DDT contains
Amount reaches 1.125mg/L (exceeding standard 1.25 times).Carry out groundwater pollutant monitoring, control research, to protection groundwater resources from
Pollution by pesticides tool is of great significance.
Phreatic water, refers to the water-bearing layer in 60 meters of below earth's surface.Owing to its buried regions is shallow, filter without deep layer rock,
Water body is easily by sewage and the pollution by pesticides of farmland residual of plant emissions.Drink contaminated underground water, have a strong impact on people
Healthy.Various physics that the agricultural chemicals such as Pesticide Residue in Soil are converted by Chinese scholars, chemical and biochemical
The mechanism of action has carried out substantial amounts of theory and experimentation, and has obtained much useful regular understanding.In recent years, people
Set up various contaminant transportation model to simulate the agricultural chemicals such as pesticide and residue thereof in soil and groundwater
Return and become and migrate.But this type of research, is only limitted to lab simulation or computer simulation, can not truly reflect that the complexity of reality is many
The field situation become.
Summary of the invention
Goal of the invention: for solving problems of the prior art, the present invention provides a kind of Shallow Groundwater Pollution thing prison
Examining system, this system be particularly well-suited to monitor quality of groundwater observation, index include pH, dissolved oxygen, oxidation-reduction potential, COD,
