Description
Technical field
The invention proposes a kind of methods of underground water multilayer undisturbed monitoring, belong to environmental pollution monitoring and repairing and treating
Technical field.
Background technique
Underground water refers to water of the preservation in below ground rock gap, refers to that groundwater level or less is saturated aqueous in the narrow sense
Water in layer, it is very close with the relationship of the mankind, it can be used as the water source of resident living water, industrial water and farmland irrigation water
Development and utilization.However the variation of natural conditions, mankind's industrial and agricultural production and daily life usually cause chemical composition of groundwater, object
Rationality matter and biological characteristics change and decline quality, the contaminated phenomenon of underground water occur, due to complex formation, underground
Water flowing is extremely slow, and therefore, underground water pollution has the characteristics that process is slow, is not easy to find and be difficult to administer.Underground water one
Denier is contaminated, even if thoroughly eliminating its pollution sources, also more than ten years or even decades can just be such that water quality restores.
Whole nation underground water detection network and big regional monitoring system are all completed substantially at present, to totality and region water quality feelings
Condition energy effective monitoring.With the development of domestic site remediation administration project, various contaminated site pollutants direct or through dirt
Research and the reparation for contaminating soil bacterial diversity underground water are also more and more, relative to the groundwater monitoring in the whole nation and area, this kind of underground
Water monitoring has monitoring range small, and the quality of groundwater difference of different zones and depth is big, with reparation and Natural Attenuation water quality
The features such as variation is big, and long-term and duration is needed to monitor.
The characteristics of current groundwater monitoring takes construction underground water online or sampling monitoring more, this monitoring is acquisition sample
Product are usually underground water surface layer sample, it is difficult to are monitored to different depth and bottom sample, if necessary to different depth
It is lauched and is monitored, then need to build the nested monitoring well of several mouthfuls of different depths, such shaft building higher cost.Monitoring well is built simultaneously
At the time it is longer after, influenced by surface water and underground water etc., online monitoring data and water intaking sample representativeness it is impacted, need
It is eliminated by modes such as regular well-flushings, thus further increases operating cost and operator monitoring amount.Therefore, in a well
Realize underground water multilayer undisturbed on-line monitoring and sampling, and can conveniently well-flushing, invent a kind of underground water multilayer unperturbed
The method of dynamic monitoring is with regard to particularly important.
Summary of the invention
In consideration of it, technical problem solved by the invention is to build multilayer undisturbed in same shaft building point and monitor system, it can
Quick well-flushing and sampling carry out polluted underground water efficient, undisturbed more for different polluting properties and hydrogeologic condition
