Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a wastewater treatment device which is convenient for discharge. Background Art

[0002] Wastewater treatment is the use of physical, chemical and biological methods to treat wastewater, purify the wastewater, reduce pollution, and even recycle and reuse wastewater to make full use of water resources.

[0003] Wastewater treatment has many advantages: Saving water resources: After treatment, wastewater can be reused in production or life, reducing the demand for fresh water resources and saving water resources;

[0004] Promoting sustainable development: Wastewater treatment is one of the important means to achieve sustainable development, which can promote resource recycling and reduce waste;

[0005] Reduce the risk of disease transmission: Wastewater treatment can kill pathogens, reduce the risk of disease transmission, and ensure public health safety.

[0006] Wastewater treatment methods can be divided into the following three categories:

[0007] Physical treatment method: Use physical action to remove suspended matter, grease and other impurities in wastewater. Common physical treatment methods include sedimentation, flotation, filtration, sedimentation, ion exchange and reverse osmosis;

[0008] Chemical treatment method: using chemical reactions to remove dissolved pollutants in wastewater. Common chemical treatment methods include neutralization, oxidation, reduction, adsorption and chemical precipitation;

[0009] Biological treatment method: Use the biodegradation of microorganisms to remove organic matter and nutrients such as nitrogen and phosphorus in wastewater. Common biological treatment methods include activated sludge method, biofilm method, biological contact oxidation method and biological rotary disc.

[0010] The choice of wastewater treatment method depends on the nature of the wastewater and the treatment requirements. Usually, a comprehensive treatment process combining multiple methods is adopted to achieve better treatment results.

[0011] At present, in the sedimentation stage of wastewater treatment, after the garbage in the wastewater is initially filtered out, the main process is to re-filter larger particles and suspended matter. In some factory areas, in order to facilitate the use of wastewater, a small tower-shaped wastewater filtration structure is generally used. Water is sent into a container and filtered through a filter net to obtain wastewater without obvious impurities. However, after long-term use, the filtration structure and the inner wall of this type of container are prone to dirt, which makes cleaning relatively cumbersome. Utility Model Content
