Analysis of the advantages and disadvantages of industrial wastewater treatment process SBR

Dec 24, 2020

advantage:

The ideal push flow process increases the driving force of biochemical reaction, improves efficiency and stable operation effect;

Resistant to shock load, there is treated water retained in the pool, which dilutes and buffers the sewage, and effectively resists the impact of water and organic pollutants;

The concentration gradient of DO and BOD5 in the reaction tank can effectively control the expansion of activated sludge;

Has a good denitrification and phosphorus removal effect;

The technological process is simple and the cost is low.

Disadvantages:

High requirements for automation control;

The drainage time is short, and the sedimentation sludge layer is required not to be stirred during drainage, so a special decanter is required, and the requirements for the decanter are very high;

The post-processing equipment requirements are large.
