Title:
SEDIMENTATION TYPE SLUDGE IN-SITU TREATMENT DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2022/088328
Kind Code:
A1
Abstract:
The present invention relates to the technical field of environmental protection apparatuses, in particular to a sedimentation type sludge in-situ treatment device and method. The sedimentation type sludge in-situ treatment device comprises a trap pipe (2) and a sludge conveying pipe, wherein the trap pipe (2) is configured to be placed in a lake bed (7) or a riverbed, and a trap cavity used for storing sludge (5) is formed inside the trap pipe (2); and a lower end of the sludge conveying pipe extends into the trap cavity of the trap pipe (2), such that the sludge at the bottom of the trap cavity can be pumped out. By means of the solution, the sludge is dried and dewatered in situ, such that secondary environmental pollution of cleared sludge is reduced. In addition, by means of the solution, the sludge can be concentrated in the trap pipe for water isolation treatment by using natural factors such as lake flow, and disturbance to benthic habitats is small, the influence range is small, and damage to ecology at the bottom of the water is small.
