Small-size low energy consumption sewage aerobic treatment device

Technical Field

The utility model relates to the field of sewage treatment, in particular to a small-sized low-energy-consumption sewage aerobic treatment device.

Background

In the field of sewage biological treatment, various aerobic aeration treatment processes are commonly adopted. The main operation modes of the aerobic aeration tank comprise a plug flow type, a complete mixing type, a stage aeration type and the like. The common plug-flow aeration tank has high treatment efficiency, but has poor adaptability to impact load, and is easy to cause the conditions of insufficient oxygen supply at the front end and excessive oxygen supply at the rear end, thereby causing energy consumption. The complete mixing is to make the water quality in the pool uniform by using blast and mechanical stirring, and the impact load resistance is strong, but the water inflow can be short flow, resulting in poor water quality of the water outflow.

The prior engineering application is better a process combining a complete mixing type and a plug flow type, and the process not only can ensure the water outlet effect, but also has a certain load impact resistance, such as an oxidation ditch process. The oxidation ditch technology utilizes aeration rotary brushes and various flow pushing devices, generally controls the sewage flow rate in a pool to be not less than 0.3m/s, has higher energy consumption, is not suitable for a small sewage treatment station with daily water treatment quantity of less than 50m3, and further reduces the working efficiency.
