Description

Technical Field

[0001] This utility model relates to the field of industrial wastewater treatment technology, and in particular to a highly efficient industrial wastewater filtration device. Background Technology

[0002] Industrial wastewater contains a large amount of suspended particulate matter, heavy metal ions, and organic pollutants. Direct discharge of such wastewater can severely pollute water resources and the soil environment. Filtration is one of the core steps in industrial wastewater treatment.

[0003] However, most existing filtration devices use a single filter media, which has problems such as low interception efficiency, easy clogging of the filter media, and the need for frequent shutdowns for maintenance. Traditional sand filters have poor interception effect on fine suspended particles, and the sand layer is prone to caking, requiring replacement of the filter media during maintenance, which is costly. Although membrane filters have high filtration accuracy, the membrane modules are easily clogged by pollutants, and the backwashing effect is poor, resulting in a continuous decline in filtration efficiency and affecting the treatment effect. Therefore, we propose a high-efficiency interception industrial wastewater filtration device. Summary of the Invention

This filtration device adopts a three-stage gradient filtration structure with multi-stage interception filtration modules, which progressively intercepts large particulate impurities and tiny pollutants, resulting in high interception efficiency and stable effluent quality that meets standards. It is suitable for treating high-concentration industrial wastewater in the chemical, metallurgical, and electroplating industries. The pretreatment module reduces the impact of large particulate impurities on subsequent filter media, and the intelligent backwashing module regularly cleans the surface residues of the filter media, preventing filter media blockage and effectively extending the service life of the filter media.
