Description

Technical Field

[0001] The utility model belongs to the technical field of biological denitrification and dephosphorization sewage treatment devices, and particularly relates to a biological denitrification and dephosphorization sewage treatment device with an easily opened and closed upper cover. Background Art

[0002] Biological denitrification and phosphorus removal sewage treatment equipment is a kind of equipment used in the field of sewage treatment, which is mainly used to remove nutrients such as nitrogen and phosphorus contained in domestic sewage or industrial wastewater to prevent eutrophication of water bodies and improve water quality. The treatment device is often mixed with sewage by adding treatment agents, but the common biological denitrification and phosphorus removal sewage treatment equipment has a large volume, so its upper cover has a large weight, which makes it difficult to open and close the upper cover. The difficulty in opening and closing the upper cover will cause great trouble to the daily maintenance, cleaning, inspection and repair of the equipment, such as cleaning scum, checking the status of biofilm, adding or replacing fillers, etc.

[0003] Secondly, the sewage treatment process may need to be adjusted in real time according to the operating conditions, such as adding chemicals, adjusting the aeration volume, etc. The inability to easily open the top cover will limit the flexibility and timeliness of these process controls.

[0004] In summary, the biological denitrification and phosphorus removal sewage treatment device whose upper cover is not easy to open and close has some problems in use, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
