涉及的是污水厂产生的脱水污泥经固化处理后进行室内试验的制样器，能够实现固化污泥室内试验的快速制样，并达到均匀标准的制样目的，可为大量污泥固化处理后进行填埋处置或资源化利用物理力学性质的研究提供试验基础，
It refers to the sample preparation device for indoor test of dewatered sludge produced by sewage plant after solidification treatment, which can realize the rapid sample preparation of indoor test of solidified sludge and achieve the purpose of uniform standard sample preparation, and can provide an experimental basis for the study of physical and mechanical properties of landfill disposal or resource utilization of a large number of sludge after solidification treatment,
也可在土工试验技术领域推广，属于资源利用与环境保护技术领域。
It can also be popularized in the field of geotechnical test technology, belonging to the technical field of resource utilization and environmental protection.
