Description

Waste water treatment device

Technical Field

The utility model relates to the technical field of wastewater treatment devices, in particular to a wastewater treatment device.

Background

Sewage treatment is a well known process for purifying sewage to the point where it is discharged into a body of water or reused. The sewage treatment is widely applied to various fields such as buildings, agriculture, traffic, energy, petrifaction, environmental protection, urban landscapes, medical treatment, catering and the like.

Aeration is an intermediate process of aerobic biological treatment of sewage, and an aeration disc is usually arranged in an aeration tank to enable gas to generate a large amount of bubbles in water so as to increase the contact area of water and air, but the bubbles generated by the aeration disc can float upwards from the water directly, so that the sewage treatment efficiency is reduced.
