Problems solved by technology

For a long time, my country's sewage treatment industry has been influenced by the traditional "heavy water and light mud" thinking, resulting in the safe, effective and hygienic treatment and disposal of sludge has not been well resolved.
At present, there are few reports on the domestic research on the sample preparation device and sample preparation method for the indoor test of solidified sludge. The present invention has developed a complete set of simple, quick, convenient and practical operations based on the same sample preparation method for this problem, and is uniformly used for the indoor test of solidified sludge. The advanced sample preparation device can quickly prepare uniform and standard samples, and can provide a test basis for the study of physical and mechanical properties of a large amount of sludge after solidification treatment, and also provide a solution to the lack of safe disposal of a large amount of sludge in the field of environmental engineering. Provide technical support for experiments

Abstract

The invention discloses a sampling device for a laboratory test of sludge solidification treatment and a sampling method thereof. The sampling device is used for static pressure sampling, compaction sampling and desampling and mainly comprises a jack, a fixed bracket, a base, a lower clamping ring, an upper clamping ring, a splitting die, a die protecting device, a force transferring guide rod, a counterforce top plate and a compaction hammer. The sampling method is used for performing the static pressure sampling, the compaction sampling and the desampling by utilizing the device. According to the sampling device and the sampling method, uniform standard samples can be quickly prepared, the operation is simple, rapid, convenient and practical, an experimental basis can be provided for the research on physical and mechanical properties after the solidification treatment is performed on a large amount of sludge, and the sampling device and the sampling method can be popularized in the technical field of soil tests.

Description

technical field [0001] The invention relates to a sample preparation device and a sample preparation method for indoor test after solidification treatment of dewatered sludge produced by a sewage treatment plant, which can realize rapid sample preparation of solidified sludge indoor test and achieve the purpose of uniform standard sample preparation. It can provide a test basis for the study of the physical and mechanical properties of landfill disposal or resource utilization after a large amount of sludge is solidified, and can also be promoted in the field of geotechnical testing technology, belonging to the technical field of resource utilization and environmental protection. Background technique [0002] Sludge is the product of dehydration of sewage, mainly organic matter, and contains a large number of microorganisms, pathogens, heavy metals, etc. For a long time, my country's sewage treatment industry has been influenced by the traditional idea of ​​"heavy water and ...
