Description

Technical Field

[0001] This utility model relates to the field of environmental governance technology, specifically a wastewater treatment device. Background Technology

[0002] With urbanization and industrial development, water consumption is increasing and water resources are becoming increasingly scarce. Meanwhile, sewage discharge is also increasing, causing more severe environmental pollution. During sewage treatment, sludge in sedimentation tanks needs to be discharged through the drain pipe. Existing sedimentation tank drain pipes have a relatively simple structure, and the inlet cannot accommodate larger sludge lumps, leading to blockages that affect usability. Furthermore, clearing blockages is inconvenient, limiting the widespread application of this technology. Existing sewage treatment devices still retain moisture in the sludge after filtration, failing to achieve proper dry-wet separation. Additionally, the large volume of sludge makes subsequent recycling difficult. Utility Model Content
