Embodiment Construction

[0028] In order to make the purpose, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0029] Please refer to figure 1 , the embodiment of the present invention provides a solidified sludge seepage liquid collection test device, including a seepage system containing a sample 12, and a drain pipe 14 connected to the seepage system for monitoring the test sample. A monitoring system for the exudate exuded from the sample 12 and a pressure system connected to the exudate system for making the sample 12 exudate the exudate. The sample 12 is the solidified sludge sample and the polluted water sample around it at the construction site.

[0030] Described pressure system comprises nitrogen cylinder 1 and water tank 5, and described nitrogen cylinder 1 connects the upper end of described water tank through inlet line 4 and makes nitrogen enter de...

Abstract

A solidified sludge percolate collection and testing device is provided. The device includes a percolating system containing a test piece, a monitoring system connected to the percolating system through a liquid discharging pipeline and used for monitoring percolation of the test piece, and a pressure system connected to the percolating system and used for allowing the percolate to percolate through the test piece. The pressure system includes a nitrogen cylinder and a water tank containing deionized water. The nitrogen cylinder is connected to the upper end of the water tank through a gas feeding pipeline to allow nitrogen to be fed into the water tank from the upper end of the water tank. The lower end of the water tank is connected to the percolating system through a water feeding pipeline so that the deionized water from the lower end of the water tank enters the percolating system through the water feeding pipeline. A beneficial effect is that the device can simulate heavy metal releasing, migration and transformation processes in solidified sludge under long-term seepage effects.

Description

technical field [0001] The invention relates to the technical field of environmental rock and soil and environmental engineering, in particular to a device and method for collecting and testing solidified silt exudate. Background technique [0002] With the acceleration of urbanization, a large amount of discharge of domestic and industrial wastewater has caused the pollution of rivers and lakes. Contaminated sludge is characterized by high moisture content, high organic matter content, and is rich in a large number of pollutants. Among them, heavy metal ions are the main pollutants in sludge, which cannot be degraded by microorganisms in the natural environment. Once the heavy metal ions in the sludge enter the biosphere through dissolution and migration, they will be enriched under the biomagnification of the food chain, interact with the protein in the animal body, and affect the normal physiological activities of the animal. In addition, the high salinity in the sludge...
