Description
Technical field
The invention belongs to environmental monitoring technology field, and in particular to one kind pollution long-term sampling equipment of place phreatic water
And application method, the long-term sampling monitoring especially suitable for contaminated regional phreatic water.
Background technology
As economic development and the acceleration of urbanization, production are more next with house refuse, architecture sediment and contaminative discarded object
It is more, cause soil and underground water pollution problem more serious.Particularly some mankind's activities, under percolate from garbage filling field
Ooze, industrial park pollution sources subsurface disposal or leakage, the pollution etc. of rural activity, pollute and oozed under thing to phreatic water,
And bigger coverage is diffused to through hydraulic action, cause different degrees of underground water pollution.Correlation study data shows, I
State's contamination type place accounting is up to 31.7%.
In recent years, government is greatly improved to the degree of concern of underground environment and the environmental consciousness of the public, makes
Obtain supervision department and industrial market gradually increases to the demand of underground pollution monitoring control technology.At present, in order to explore Pollution Field
Area's environment prophylactico-therapeutic measures simultaneously lifts the excellent degree of environment, expedites the emergence of and develops numerous contaminated site environmental improvement technologies, wherein, enter
The underground water sampling on row pollution stratum simultaneously coordinates dependence test to provide largely physics, chemistry and the microorganism letter on stratum
Breath, it is that the monitoring means to play an important role is assessed to engineering development and Environmental security.
Carry out the sampling monitoring of pollution stratum phreatic water both at home and abroad at present mainly to set groundwater monitoring well, and
Based on the means sampled in well, there is its shortcoming in this technology, predominantly：First, monitoring well shaft building tedious process, shaft building cost
