Description

Technical Field

[0001] This utility model relates to the field of biological denitrification technology, specifically a biological denitrification treatment device. Background Technology

[0002] Biological denitrification is a commonly used treatment process for wastewater pretreatment. The wastewater to be treated is injected into a designated biological denitrification wastewater treatment tank for ammonia removal treatment. However, the wastewater treatment tank needs to be supplied with oxygen through an aeration device during operation.

[0003] In existing wastewater treatment ponds, the aeration pipes of the aeration devices are mostly laid at the bottom of the pond. The corresponding liftable aeration pipes are then installed through these pipes. However, after prolonged use, the liftable aeration pipes of these existing devices are prone to damage, leading to cracks. This results in a larger aeration volume at the cracked section, affecting the aeration volume of other liftable aeration pipes. Furthermore, maintenance requires emptying the wastewater treatment pond, which is a cumbersome process and makes the devices impractical. Utility Model Content
