Description

A sewage treatment tank Technical Field

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

[0002] Wastewater treatment is a crucial environmental protection measure. Its purpose is to use a series of scientific and rigorous physical, chemical and biological treatment methods to make wastewater meet the water quality standards for discharge into a specific water body or to meet the strict requirements for safe reuse, thereby achieving the recycling of water resources and the effective protection of the ecological environment.

[0003] Existing wastewater treatment tanks play a crucial role in environmental protection and water resource recycling, and the filter screen, as its core component, directly affects the efficiency and quality of wastewater treatment. However, current filter screen designs in wastewater treatment tanks generally suffer from the problem of inconvenient sludge cleaning. During continuous wastewater filtration, filters inevitably accumulate large amounts of sludge and impurities. These deposits not only gradually cover the filter screen surface but also penetrate into the filter screen's pores. Traditional filter screen cleaning methods are mostly cumbersome and time-consuming, usually requiring professionals to spend considerable manpower and time disassembling the filter screen and then manually brushing or rinsing it with a high-pressure water gun. This not only increases operating costs but may also damage the filter screen due to frequent disassembly. Simpler cleaning methods, such as mechanical vibration or airflow purging, are often ineffective in thoroughly removing stubborn sludge from the filter screen surface and pores. Over time, the filter screen pores gradually become clogged, severely affecting its filtration performance. This not only reduces wastewater treatment efficiency but may also lead to a decrease in the overall efficiency of the wastewater treatment system due to obstructed water flow, failing to meet current needs.
