Description

Technical Field

[0001] This application relates to the field of pollutant treatment, and in particular to a wastewater treatment apparatus. Background Technology

[0002] With the rapid growth of urban population and the continuous development of industrial and agricultural production, the discharge of industrial wastewater and urban sewage has increased dramatically, far exceeding the self-purification capacity of natural water bodies. Currently, water pollution in my country is becoming increasingly serious, affecting almost the entire country. These pollutants not only damage aquatic ecosystems but also threaten human health, leading to problems such as drinking water source pollution, eutrophication (cyanobacterial blooms), and the accumulation of biotoxicity.

[0003] To address this challenge, wastewater treatment technologies have continuously advanced, from traditional physical sedimentation and chemical coagulation to biological treatment and advanced oxidation and membrane separation processes, with various methods being developed and applied. However, existing wastewater treatment devices still have many limitations. Traditional microporous aeration discs are prone to scaling and have low oxygen utilization, resulting in reduced pollutant treatment efficiency. Utility Model Content

The packing plate is detachably connected to the upper end of the partition. A hinged column is fixedly connected to the outer wall of the aeration disc. The hinged column is rotatably connected to the inner wall of the receiving cavity.

[0007] By adopting the above technical solution, the microorganisms attached to the packing plate decompose organic pollutants in sewage or waste gas through metabolism, transforming them into harmless substances or stable residues. The aeration disc is connected to external oxygen to provide the necessary dissolved oxygen for the microorganisms, enhance their activity, and improve degradation efficiency.

A hinged column is fixedly connected to the outer wall of the connecting plate, and the aeration pipe is fixedly connected to the end of the connecting plate facing the partition.

The motor housing of the drive motor is fixedly connected to the support plate. The motor shaft of the drive motor is fixedly connected to one end of the second connecting rod, and the other end of the second connecting rod is hinged to the sliding sleeve.

[0013] By adopting the above technical solution, the rotation of the second connecting rod drives the first connecting rod to swing through the slider, causing the aeration disc to swing repeatedly, reducing dirt accumulation, reducing aeration dead zones, and improving pollutant treatment efficiency.

[0014] Preferably, a support block is fixedly connected to the inner wall of the receiving cavity, and the partition is slidably connected to the inner wall of the receiving cavity, with the support block used to support the partition.

[0016] Preferably, the partition has an opening that extends vertically through the partition, and a fixing block is fixedly connected to the upper end of the partition. The upper end of the fixing block has an insertion groove for inserting a filler plate.

[0017] By adopting the above technical solution, the detachable design of the packing plate and the partition facilitates the replacement or cleaning of the packing, maintains the activity of the biofilm, and improves the efficiency of pollutant treatment.

[0018] Preferably, the groove wall of the insertion slot is fixedly connected with an anti-detachment strip, and the outer wall of the filler plate is provided with an embedding groove for the anti-detachment strip to slide into.

[0022] Preferably, there are multiple packing plates, and the multiple packing plates are spaced apart along the length of the box.

[0023] By adopting the above technical solution, multiple packing plates increase the contact area between pollutants and microorganisms, thereby improving cleaning efficiency.

[0024] Preferably, the box includes a main body and a cover, the cover being detachably connected to the main body, and the main body and the cover together forming a receiving cavity.
