Description

Technical Field

[0001] The utility model relates to the technical field of wastewater filtration, in particular to a tubular microfiltration device for filtering heavy metal wastewater. Background Art

[0002] The acceleration of industrialization has led to the discharge of a large amount of heavy metal-containing wastewater, which poses a serious threat to the environment and human health. Heavy metal wastewater mainly comes from industries such as metallurgy, electroplating, electronic manufacturing, chemical industry and mining. The wastewater often contains heavy metal ions such as lead, mercury, cadmium and nickel. These harmful substances are difficult to degrade naturally and have strong toxicity and bioaccumulation. In water bodies, heavy metal ions can damage aquatic organisms and ecosystems, and enter the human body through the food chain, endangering health. Traditional heavy metal wastewater treatment methods such as chemical precipitation and ion exchange have problems such as low treatment efficiency, complex operation and high operating cost. Therefore, an efficient and simple wastewater treatment device is urgently needed. Through optimized design, the device can effectively remove heavy metal ions in wastewater, improve treatment efficiency and water quality, and is suitable for various heavy metal wastewater treatment needs. It has the advantages of compact structure, simple operation and stable operation. It is widely used in industrial wastewater treatment, environmental remediation and other heavy metal wastewater treatment fields.

[0003] Existing heavy metal wastewater treatment devices have some shortcomings in actual use. First, traditional treatment methods have limited effects on the removal of heavy metal ions, making it difficult to meet strict environmental protection requirements and affecting the quality of treated water. Secondly, existing devices are usually complex in structure, with cumbersome operation and maintenance steps, and high technical requirements for operators, which increases the difficulty of use and maintenance costs. In addition, traditional devices are prone to problems such as blockage and equipment failure during operation, affecting treatment efficiency and stability. Furthermore, some devices are bulky and occupy a large space, which is not conducive to application in small or mobile treatment stations. Therefore, we provide a tubular microfiltration device for filtering heavy metal wastewater. Utility Model Content
