Description
Technical Field
The utility model belongs to the technical field of the water sampling, especially, relate to a filter material stratified sampling ware of water supply plant.
Background
The water supply plant filter is divided into a quartz sand filter and a biological activated carbon filter, wherein the quartz sand filter intercepts suspended substances and colloidal substances in water through a sand layer; the biological activated carbon utilizes the porous adsorption of the activated carbon filter material and the biodegradation characteristic of surface microorganisms to remove organic matters, ammonia nitrogen and other micropollutants and chlorine disinfection by-product precursors in water, thereby purifying the water. The sampling is difficult because of the limitation of the thickness of the filter material (the thickness of the sand layer is generally 0.9-1.5m, and the thickness of the biological activated carbon is 1.0-2.5 m). By adopting the existing mixing sampler, filter materials with different depths cannot be accurately obtained, and the vertical performance analysis of the filter materials and the comprehensive evaluation of the filter material efficiency are influenced. Therefore, how to solve the problem of difficult layered sampling of the filter material, realize simple and accurate layered sampling, provide real and reliable test data for the management and research of the sand/carbon filter, and become an important research subject.
The scientific and effective stratified sampling requirements are as follows: (1) accurately sampling under the conditions that normal production is not influenced (namely, the pool is not stopped) and the original layering of the sample is not damaged; (2) the sampling operation is simple, convenient and fast, and the use is convenient. Although the existing sampler can obtain a filter material with a certain depth, the existing sampler has the following defects: (1) the existing sampler is heavy and inconvenient to carry; (2) only a single-layer filter material can be obtained by sampling each time; (3) in the sampling process, the sand/carbon is more compact due to the action of water pressure, and the sampler is harder to reach the expected depth and take out; (4) in the process of inserting and taking out the sampler, the disturbance to the natural filter layer is large, and the obtained sample often has a layer mixing phenomenon, so that the measurement result is influenced.
SUMMERY OF THE UTILITY MODEL
To the problems existing in the prior art, the utility model provides a filter material stratified sampling ware of water supply plant.
The utility model discloses a realize like this, a water supply plant filter material layering sample thief includes interior pole, urceolus, interior pole upper end screw thread rotates to be connected inside the urceolus, interior pole side is seted up a plurality of sample grooves along interior pole axial direction, and is corresponding a plurality of round holes have been seted up to the urceolus side, interior pole is equipped with the scale along axial direction, and interior pole upper end is fixed with the handle.
