Description

Mechanical automation sewage treatment plant

Technical Field

The invention relates to the technical field of mechanical automation, in particular to a mechanical automation sewage treatment device.

Background

With the increase of urbanization level and the rapid expansion of population scale, the requirements for town sewage treatment are higher and higher, wherein one of the important indexes of town sewage treatment is whether the COD value reaches the standard or not. In the prior art, the main process flow of sewage treatment is as follows: the COD value is reduced by carrying out solid-liquid separation on the sewage (a sedimentation tank) and then carrying out certain biochemical treatment (aeration treatment for aerobic fermentation) so as to realize the standard discharge. One of the main disadvantages of this method is that sewage treatment plants need to occupy large area of land, and the sewage treatment speed is slow, which is difficult to meet the actual sewage treatment requirements. In order to meet the technical requirements of low energy consumption, low cost, low occupied area and the like by combining the existing sewage treatment process, a series of new sewage treatment devices and processes are developed and designed in the prior art, for example: a series of novel high-efficiency sewage treatment processes such as a three-ditch oxidation ditch method, an SBR method, a UNITANK process, a Biological Aerated Filter (BAF), a Membrane Bioreactor (MBR) and the like. However, in general, the existing treatment processes or equipment still have the disadvantages of slow treatment speed, high treatment cost and the like, and due to the huge sewage production capacity, the sewage treatment plant still needs to be further developed and designed to better meet the actual sewage treatment needs.
