Engineering case for municipal wastewater treatment by an oxidation ditch-type A2/O + Advanced treatment process

The technological parameters and running effect in the treatment of municipal sewage by an A
²
/O + Advanced treatment process are introduced and also aims to improve the application of the BIOLAK process in municipal wastewater treatment. The process flow, process parameters and structure size of the project were introduced. And the treatment effect and designing features were discussed. The running results showed that the quality of treated water could meet the requirement of first-A grand of discharge standard of pollutants for municipal wastewater treatment plant (GB189118-2002), after treated by a BIOLAK municipal wastewater treating process with nitrogen and phosphorus removal function.
