AI Technical Summary
Technical Problem
When sewage enters the existing intercepting wells, suspended solids in the sewage deposit into silt, leading to decreased effectiveness and increased dredging costs.
Method used
A municipal drainage interception device was designed, comprising a flow guiding component and an agitation component. The flow guiding component guides sewage to the agitation component through a water collection bucket and a flow guiding pipe, and uses an impeller and a stirring rod to agitate the sewage, thereby reducing sludge deposition.
Benefits of technology
It effectively reduces silt deposition inside the well, extends the maintenance cycle, reduces the cost of manual dredging, and improves the transmission efficiency of water flow impact force.
