Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a biochemical packing device for wastewater treatment. Background Technology

[0002] Domestic sewage is a type of low-concentration organic wastewater containing organic matter, nitrogen, phosphorus, oil, impurities, etc. It is usually treated with biochemical packing materials. Biochemical packing materials are the core carriers for microbial attachment, and their contact efficiency with sewage and oxygen directly determines the degradation effect of pollutants. In order to improve mass transfer efficiency.

[0003] Existing biochemical packing devices are usually used in conjunction with aeration equipment. The biochemical packing is either fixed in the treatment tank or scattered in the treatment tank. If the biochemical packing is fixed, it reduces the contact area with the sewage. If the biochemical packing is scattered, it will clump together, reducing the efficiency of water purification.

[0004] Therefore, we propose a biochemical packing device for wastewater treatment. Utility Model Content
