A sewage treatment device with filter medium recycling

Abstract

This utility model discloses a wastewater treatment device with a recyclable filter medium. By opening the first stop valve with a first turn, wastewater is discharged from the wastewater pipe into the filter box, where the filter medium within the filter plate filters the wastewater. The filtered water flows through the filter plate to the other side of the filter box and is discharged through the drain pipe. After all wastewater filtration is complete, the first stop valve is closed, and the first water pump is started to introduce a backwash component from the water tank into the filter box through the inlet pipe. The backwash component impacts the filter plate and filter medium, flushing away debris that clogs the filter plate and filter medium to the other side of the filter box. Then, by turning the second turn, the second stop valve is opened, and the flushed debris and water are discharged through the waste discharge pipe. This solves the technical problem of filter media easily becoming ineffective due to clogging or adsorption saturation, requiring frequent replacement, leading to high costs and resource waste.

Description

Technical Field

[0001] This utility model relates to the field of wastewater filtration media technology, specifically to a wastewater treatment device that recycles filtration media. Background Technology

[0002] The recycling of filter media in wastewater treatment is primarily due to the following reasons: First, it conserves resources and reduces reliance on natural materials; second, it lowers operating costs by extending the media's lifespan through regeneration or reuse; third, it reduces solid waste and avoids secondary pollution from landfill or incineration; and fourth, it improves treatment efficiency, such as restoring adsorption performance after activated carbon regeneration, ensuring water quality meets standards. Recycling aligns with the concept of resource utilization and contributes to low-carbon, environmentally friendly, and sustainable development.

[0003] Traditional wastewater filtration typically involves installing a filter box inside the pipeline. This box contains filter media such as quartz sand, activated carbon, anthracite, and magnetite. The filter media removes suspended solids, organic matter, heavy metals, and other pollutants from the wastewater through methods like trapping, adsorption, or chemical reactions. Once the pollutants in the wastewater have been treated by the filter media, it is discharged, completing the wastewater treatment process and preventing environmental pollution. However, filter media are prone to clogging or saturation and become ineffective, requiring frequent replacement, leading to high costs and resource waste. Utility Model Content

[0004] The purpose of this invention is to provide a wastewater treatment device that recycles filter media, in order to solve the technical problem that filter media are prone to failure due to clogging or adsorption saturation, requiring frequent replacement, which leads to high costs and waste of resources.
