Description

Technical Field

[0001] The invention relates to the technical field of biofilm treatment, and in particular to a biofilm multi-stage treatment device for industrial wastewater with a telescopic mechanism. Background Art

[0002] Industrial wastewater refers to wastewater, sewage and waste liquid generated in the process of industrial production, which contains industrial production materials, intermediates and products lost with water, as well as pollutants generated in the production process. With the rapid development of industry, the types and quantities of wastewater have increased rapidly, and the pollution of water bodies has become increasingly widespread and serious, threatening human health and safety. For environmental protection, the treatment of industrial wastewater is more important than the treatment of urban sewage, especially some heavy metal wastewater discharged from mining, smelting, electrolysis, electroplating, pesticides, medicines, paints, pigments and other enterprises. If heavy metal wastewater is not treated, it will seriously pollute the environment. The types, contents and forms of heavy metals in wastewater treatment vary from different production enterprises. Heavy metal removal is very important in wastewater treatment.

[0003] At present, the existing biofilm multi-stage treatment devices for industrial wastewater still have shortcomings during use. During use, the disk surface of the existing biofilm treatment device is covered with a film-like substance formed by the growth of microorganisms. Since the spacing between the disks is fixed, after a period of use, the spacing between the disks cannot be adjusted accordingly according to the activity of the microorganisms, which not only affects the growth environment of the microorganisms, but also affects the microbial purification efficiency, reducing the use effect of the product.
