Description

Technical Field

[0001] This utility model relates to a solid-liquid separation device for environmental engineering, specifically a solid-liquid separation device for environmental engineering, belonging to the field of solid-liquid separation technology. Background Technology

[0002] Solid-liquid separation devices in environmental engineering are used to separate solid substances from liquids, and are widely used in sewage treatment, wastewater management, and solid waste treatment. These devices separate solid particles from liquids through physical, chemical, or biological methods, thereby reducing the concentration of pollutants in the liquid, increasing water reuse rates, reducing environmental pollution, and protecting ecosystems. However, many existing solid-liquid separation devices lack backwashing mechanisms in their filtration systems, leading to frequent clogging of easily clogged filter plates. This results in excessive pressure differences between the upstream and downstream of the filtration system, which not only reduces the efficiency of solid-liquid separation but also increases the likelihood of filter plate rupture. This invention effectively performs backwashing on easily clogged filter plates, reducing the pressure difference between the upstream and downstream of the filtration system and the frequency of filter plate replacement, thus reducing the maintenance costs of the filtration device. This has significant practical value. Utility Model Content
