Abstract
Description
Technical Field
[0001] This utility model relates to the field of water treatment engineering, and in particular to a sewage discharge dam for water environment management. Background Technology
[0002] In water environment management, engineering waterway dams are water pollution interception devices used to prevent the spread of water pollution and reduce the entry of pollutants into water bodies. They also effectively drain water and facilitate construction work within the interception area. Common waterway protection and interception structures include fences and isolation nets to block debris in the water, and water is pumped out by constructing the interception dam. However, during implementation, these structures often become clogged at the interception outlets or pump inlets, resulting in slow water discharge during the waterway interception and dredging process, directly impacting the project's progress.
[0003] It can quickly intercept and pump water during construction and effectively remove debris from the water area to achieve optimal protection and treatment effects. Furthermore, it is mainly used for the prevention and control of water pollution, effectively protecting the quality of the water environment and the health of water in ecological water systems, serving as an effective improvement to current water environment management goals.
