Description
Technical field
The invention belongs to the environment monitoring technical field, be specifically related to a kind ofly can accurately simulate groundwater seepage simulation test device and the simulation experiment method of inland lake Lakesides soil to the Shallow Groundwater Pollution situation.
Background technology
It is the major issue that China faces at present that inland lake pollutes with eutrophication, administering the inland lake pollution huge with the required investment amount of eutrophication, accurately judge all kinds of pollution sources, enter the lake rule, is accurately to formulate countermeasured to bring inflation under control, the reduce cost waste, improve the basic guarantee of administering performance.
The rainfall situation of hinterland is generally to be seasonal variety, and lake level is respective change also.The Lakesides shallow ground water is limited by water body in lake, the lake level lifting, and the corresponding lifting of Lakesides underground water table, in lifting process, Lakesides soil is in and soaks and control in dried state.In soil, especially in the mold of top layer, contained organic matter, nitrogen phosphorus can reach several thousand to several ten thousand ppm usually; In the shallow ground water of lakeside, organic matter, nitrogen phosphorus are usually below 100ppm, even close to zero.During seasonal the immersion, pollutant spreads in underground water from soil, until reach balance.Arrive when dry season, the lake water water level descends, and shallow ground water imports the lake body, and pollutant shifts and enters the lake body from soil thereupon.Because Lakesides distributes in the form of a ring, the process of pollution is slow, hidden, and is very large to the description difficulty of the type local ground watering pollution condition.
At present, study this pollution type and mainly adopt the mode of excavation inspection well to carry out dynamic monitoring, gather different Observational depth sampling of ground waters, analyze the level of pollution of underground water.Although the inspection well method can directly reflect the pollution situation of observation station, but can only obtain water quality data, it is the pollution level of Lakesides underground water, still need rely on the model measuring and calculating for the defeated data of polluting the water yield of moving, total amount of pollutants discharge (water quality the multiply by the water yield) result reliability that uses the method to record can't directly be verified.Simultaneously, application the method need to arrange a plurality of observation stations, causes investment large, and it is also high that the collection in worksite sample comes and goes cost.Therefore, develop the groundwater seepage simulation test device of a kind of accurate simulation inland lake Lakesides soil to the Shallow Groundwater Pollution situation, very necessary.
Summary of the invention
The first purpose of the present invention is to provide a kind of simple in structure, and working stability is reliable, can accurately simulate the groundwater seepage simulation test device because of groundwater contamination situation due to the Soil Hydrological state variation of lake, shore; Another object of the present invention is to provide a kind of application process of this device of application.
The first purpose of the present invention is to realize like this, comprise column casing, substrate water tank, supply tank and operation valve, described column casing bottom arranges the substrate water tank, and described substrate water tank is communicated with supply tank by operation valve, feed pipe, and described supply tank is the water tank that liftable is regulated; Described substrate water tank is arranged on support, and the substrate water tank bottom arranges draining valve.
Another object of the present invention be achieved in that comprise that sampling point is chosen, sample soil gathers, the pre-service of sample soil, column casing filling, underground water soak test, pollution water sample collection, water sample analysis, the calculating of pollution output quantity, specifically comprise the following steps:
