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 sample preparation device and a sample preparation method for the indoor test of sludge solidification treatment. The sample preparation device is used in three aspects of static pressing samples, compaction sample preparation and sample removal, and mainly includes a jack, a fixed support, a base, Lower clamping ring, upper clamping ring, split mold, mold guard, force transmission guide rod, reaction top plate, compaction hammer. The sample preparation method is to use the above-mentioned device to carry out static sample pressing, compaction sample preparation and sample removal. The invention can quickly prepare uniform and standard samples, is simple, fast, convenient and practical in operation, can provide a test basis for the research on the physical and mechanical properties of a large amount of solidified sludge, and can also be popularized in the technical field of geotechnical tests.
Description
technical field [0001] The invention relates to a sample preparation device and a sample preparation method for indoor testing of dewatered sludge produced in a sewage plant after solidification treatment, which can realize rapid sample preparation for indoor testing of solidified sludge and achieve the purpose of uniform standard sample preparation. It can provide a test basis for landfill disposal or resource utilization physical and mechanical properties of a large amount of sludge after solidification treatment, and can also be popularized in the field of geotechnical test technology, belonging to the field of resource utilization and environmental protection technology. Background technique [0002] Sludge is the product of dehydration treatment of sewage. It is mainly composed of organic matter and contains a large number of microorganisms, pathogens, and heavy metals. For a long time, my country's sewage treatment industry has been influenced by the traditional "heavy...
