Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a composite multi-stage filtration wastewater treatment device. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly becoming a part of ordinary people's daily lives.

[0003] In current wastewater treatment, wastewater is fed into a filter structure for filtration. However, direct filtration increases filtration pressure, requiring frequent cleaning or replacement of the filter plates, which increases operating costs and affects filtration efficiency. Furthermore, the open operating structure can cause exhaust fumes to escape and makes it difficult for personnel to approach and operate the equipment. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention connects the sewage pipe to one end of the inlet pipe. The control panel guides the sewage into the settling tank, where it settles. After settling, the extraction pump is activated. Suspended blocks float on the water surface, and the pump draws water through the flexible pipe and connecting pipe into the purification chamber. The water flows slowly into the purification chamber, near one side, allowing it to pass through multiple internal filter plates. The system performs filtration and purification operations, using a stepped purification chamber to filter water in multiple stages. The purified water is then discharged through a discharge pipe. Sediment at the bottom of the settling tank is cleaned by removing the sealing cover and using the side discharge chute. The top maintenance opening allows for the removal, replacement, and cleaning of multiple filter plates. The sealed operating structure ensures cleanliness and hygiene, and the combination of settling and multi-stage filtration makes wastewater treatment more comprehensive and efficient.
