Abstract
The invention relates to a soil leachate sampling device which comprises a sampling opening (A) connected with a water pump, a vacuum pump and the like, a soil leachate storage tank (C) with a sealing cover (B), a soil leachate enriching tube (D), a permeable opening (E) and the like, and is mainly used to collect the soil leachate. The device in the using process is small in disturbance on the soil, can be used for conveniently and rapidly to take samples, and can collect the soil leachate sample quantitatively in real time at a fixed depth. The device is made of a biological material, so that the device is stable in chemical properties, anti-corrosive and free from secondary pollution. The development of the device has important scientific values on the aspects of acquisition of accurate soil leachate physicochemical data, real-time tracing and monitoring on physicochemical properties of the soil leachate and promotion of the scientific research of soil, and the device is also wide in application.
Description
Technical field
The present invention relates to a kind of soil filtration liquid sampling equipment.The present invention has the disturbance of soil very little, can obtain a large amount of soil filtration fluid samples, can be regularly, quantitatively, characteristics such as depthkeeping degree collection soil percolate sample.
Background technology
Sampling thief is one of indispensable instrument of wetland field study and sampling work, particularly to the sampling thief of wetland soil solution, is to carry out the wetland biomass geochemistry and the wetland hydrology is studied one of indispensable instrument.Current wetland soil solution sampling thief adopts pvc pipe to be fixed in the different sections of soil more, extracts percolate at set intervals and obtains.Such device is that one type of suitable different soils quality (clay, loam, sand, peat soil), different sample require the conventional soil liquid sampling thief of (organism analytical sampling, heavy metal analytical sampling, top layer sampling, deep layer sampling, section sampling etc.).But the soil liquid that such device is collected needs certain hour diafiltration accumulation, in pvc pipe, preserves the long period, and the solution physicochemical property changes easily, and is bigger to later stage laboratory experiment analysis result influence.Therefore, the real-time soil liquid sampling equipment of research and development one cover for obtaining soil liquid physicochemical data accurately, is realized real-time wetland tracking and monitoring, has purposes widely.
Summary of the invention
The object of the present invention is to provide a kind of soil filtration liquid sampling equipment and method of application thereof.
In order to accomplish the object of the invention, a kind of soil filtration liquid sampling equipment comprises the sample tap (A) of device attended operations such as being used for water pump, vacuum pump, the soil filtration liquid hold-up vessel (C) that has gland bonnet (B), soil filtration liquid enrichment pipe (D) and permeable mouth (E) etc.Wherein, sample tap (A) has gland bonnet, and soil filtration liquid enrichment pipe (D) is with filter membrane (F).
According to the present invention, described soil filtration liquid enrichment pipe (D) is positioned at the bottom of soil filtration liquid hold-up vessel (C), is used for the solution seepage of soil and is filled in the soil filtration liquid hold-up vessel (C).
According to the present invention, the sample tap that provides (A) highly is generally 3.00～5.00cm, and diameter is 0.50～2.00cm; Soil filtration liquid enrichment pipe (D) length is 10.00～25.00cm, and diameter is 1.50～2.50cm, and its permeable mouthful of (E) aperture is 0.30～1.50cm; Soil filtration liquid hold-up vessel (C) diameter is 10.00～25.00cm.
According to the present invention, permeable mouthful (E) of the soil filtration liquid enrichment pipe (D) that provides is with the filter membrane (F) in 0.05～1.00mm aperture.
According to the present invention, the soil filtration liquid enrichment pipe (D) that provides is than the high 3.00～5.00cm of soil filtration liquid hold-up vessel (C), to prevent obstruction.
The present invention also provides the method for application of described equipment, comprises equipment resettlement standard and sampling method.
Resettlement standard: vertically this equipment is buried in wetland soil,, make enrichment pipe (F) identical with the test design parameter with the vertical range of soil surface according to the test design scheme.
Sampling method: 1. drain soil filtration liquid hold-up vessel (C) ponding with water pump; 2. make soil filtration liquid hold-up vessel (C) form vacuum with vacuum pump; 3. extract soil filtration liquid with instruments such as syringes from sample tap (A) after 30 minutes.
