Description
Technical field
The invention belongs to hydrophore technical field, relate to groundwater monitoring and acquisition technique, be specially a kind of method and the device measuring water level, dissolved in situ oxygen and gather different depth underground water.
Background technology
Along with the development of modern social economy, the surface water bodies such as lake, river, reservoir are all subject to pollution in various degree.2 × 10 there is every day according to introducing in " the United Nations's world water resources development Report (first published) " (executive summary)
6the rubbish of ton is poured in water, comprising industry, chemistry, life and agricultural wastes (chemical fertilizer, pesticide, pesticide residues thing) etc.Along with the aggravation of surface fresh water resource pollution, industry and sanitary sewage discharge capacity increase, and by a large amount of impact using agriculture chemical of agricultural, groundwater contamination problem also will become increasingly conspicuous.The serious area of groundwater contamination is mainly distributed in around cities and towns, river course for sewage discharge both sides, polluted-water distributive province, earth's surface and draw dirty agriculture irrigated area etc.China about has half city proper groundwater contamination relatively more serious, and pollutant mainly contains heavy metal, organism and nitrate etc., and groundwater contamination majority is combined pollution.Increasing research shows, for underground water near coastal zone, the pollutant under the effect of offshore hydrodynamic condition in underground water can occur to move and pollute littoral zone marine environment.The migration of research littoral zone underground pollutant in water and transformation rule, for coastal zone resources and environmental protection significant.At present, groundwater level meter and sampling thief form more, but level measuring and water sampling cannot be carried out simultaneously, therefore common way first measures after water level with water-level gauge to sample again, and operating process is loaded down with trivial details, needs manpower many.Measurement for underground water dissolved oxygen DO is also generally first water sample is taken out and is transferred in sampling bottle to measure, but in transfer process, inevitably make a large amount of oxygen dissolve in water sample, changes original dissolved oxygen content in underground water.General sampling thief is upper and lower opening, the water entered from end opening in sampling thief decline process may have part to accumulate in sampling thief corner and not timely from discharge suitable for reading, and sampling thief has certain length, thus the water sample gathered with require that the water sample difference of the degree of depth is larger.And general sampling thief is portable, manpower cannot be liberated, staff rock and other people are that factor all can impact the water sample by designated depth collection, make sampling accuracy lower.Above deficiency makes current groundwater sampling be difficult to meet the correlative study of underground water and the needs of investigation.
Summary of the invention
Object of the present invention is exactly the deficiency for measuring underground water table, dissolved in situ oxygen and the collection existing treatment technology of designated depth underground water and means existence, a kind of method and the device measuring water level, dissolved in situ oxygen and gather different depth underground water are provided, while adopting water, measure water level, and measure dissolved in situ oxygen and water sampling in strict accordance with designated depth.
The method of the water level measured that the present invention proposes, dissolved in situ oxygen and collection different depth underground water, concrete steps are as follows:
(1) according to the difference of ground water electric conductivity, select suitable cell voltage and microampere meter range, three-legged support is fixed on inspection well, close water gathering tube lower end outlet valve, check and build the water inlet lid of water gathering tube upper end;
(2) open battery case switch, rotate reel and pass through
wire with a scalemake the stable decline of water gathering tube, in rotation process due to wire with a scale the diameter at the place of winding be less than stay cord be wound around the diameter at place, therefore wire decline with a scale is slow, remain exceptionally straight state, stay cord then remains relaxed state, observes microampere meter pointer, when microampere meter pointer deflects, screw dogbolt immediately, the scale now on sensing tape scale wire, can obtain groundwater level;
(3) battery case switch is closed, unclamp the dogbolt of reel, be rotated further reel and screw dogbolt after water gathering tube water inlet reaches designated depth, connect dissolved oxygen meter display interface device, read and record oxygen dissolving value, unclamp dissolved oxygen meter display interface device, the firmly stay cord that is connected with water inlet lid of pull-up, open water inlet lid and keep a period of time, be full of after water gathering tube until water and unclamp stay cord, counter-rotation reel, the wire of connection water gathering tube will be made in rotation process to keep exceptionally straight state, the stay cord connecting into water cap is made to keep relaxed state, after water gathering tube to be removed, unclamp outlet valve, transfer water sample is in sampling bottle,
(4) for different inspection wells, step (1) ~ (3) are repeated.
According to electrical principles in the present invention, when utilizing copper sheet probe in water gathering tube lower end to touch the water surface, circuit communication causes microampere meter pointer to deflect to obtain water level.According to the difference of ground water electric conductivity, selected cell voltage can be 1.5V ~ 3V, and microampere meter range can be 100 μ A ~ 1mA.
The present invention controls water gathering tube water inlet lid open/close states by rope decline rate difference on different-diameter reel and gathers the water sample of designated depth.
