Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of sewage separation equipment, specifically a sewage separation and sedimentation device. Background Technology
[0002] When untreated sewage seeps into the ground, it has a strong odor and can pollute groundwater. In more serious cases, it can severely affect the local ecological balance and pollute the local environment.

[0004] Existing wastewater separation devices typically separate wastewater by simply causing the liquid to settle through vibration. This method results in slow liquid descent due to gravity, leading to low solid-liquid separation efficiency. Furthermore, impurities in the wastewater tend to accumulate, clogging the separation screen holes and making it difficult to drain the liquid, thus affecting the wastewater separation efficiency.
