Description
Technical Field
The invention belongs to the technical field of buildings, and particularly relates to a suction filtration experimental device and a suction filtration experimental method.
Background
Municipal sludge is a gelatinous waste produced in the sewage treatment process of municipal sewage treatment plants, and the sludge is discharged and stacked randomly without treatment to cause serious environmental problems. The international sludge disposal modes mainly comprise land utilization, sanitary landfill, incineration, throwing into the sea and the like, wherein the landfill disposal has relatively loose requirements on technical indexes and low operation cost and is the main mode of sludge disposal at the present stage. Simple and independent landfill, namely directly dumping the sludge into a preset landfill pit after the sludge is dewatered and digested to form a temporary sludge storage area.
The inventor finds that the water content of the sludge is high, the physical and mechanical properties are poor, the sludge cannot meet the landfill standard of municipal sludge, the reservoir capacity of a landfill is increasingly tense, and the potential safety hazard can be buried, such as the slip and landslide accidents of landfill bodies in Shenzhen lower plateau landfill and Shanxi Taiyuan landfill.
The inventor considers that at present, the domestic and foreign researches on the sludge mainly focus on the dehydration property of the excess sludge, the solidification modification of the dehydrated sludge and the like. However, there are few relevant systematic research data about degraded sludge in the landfill area, and in addition, the difference of sludge in different regions and different landfill modes also cause the landfill area to have specificity, so that the design of an in-situ reinforcement treatment and reduction scheme of the sludge reservoir area lacks necessary test parameters.
Therefore, the inventor thinks that it is necessary to take the long-term landfill sludge in the domestic temporary storage area as a research object, obtain the physical and mechanical properties of the sludge by means of geotechnical tests and summarize the change rule of relevant parameters along with underground spatial positions. Meanwhile, the urban domestic sludge is necessary to be pretreated by means of biochemistry and the like, and then deep dehydration is carried out on the long-term landfill sludge by combining mechanical pressure, so that the volume of the sludge is reduced, the water content of the sludge is reduced, the mechanical property of the sludge is improved, and the subsequent treatment requirement of the sludge is met. Necessary design parameters and basis are provided for further reinforcement and reduction of the existing sludge temporary storage area.
The inventor finds that the surprising control of the vacuum filtration device relies on the fine control of the vacuum pump, which requires many people to operate, and this causes the following specific defects:
1. more than two persons are required to be matched together during measurement, and manual reading is required; the reading accuracy is low.
2. Because the measuring device adopted at present is generally a measuring cylinder, the liquid drops can fluctuate in the process of converging to the measuring cylinder, and therefore the reading accuracy is influenced.
3. The inner wall of the existing filter paper is easy to be coated with slurry, so that the sludge is difficult to take out.
4. The existing measuring system needs to use a negative pressure source to form suction, and the vibration of the negative pressure source can influence the accurate reading of the volume of filtrate in the working process
