Analysis of the effectiveness of biological wastewater treatment

The article presents the results of research on the analysis of the effectiveness of biological wastewater treatment, which includes a dosing device for injecting liquid biological preparations into sewage pumping stations, wastewater aeration and a bioplat (hydrobotanical system). The object of the study: sewage treatment plants (filtration fields with boning), into which industrial wastewater from a dairy processing enterprise is constantly discharged. The research results showed that according to such indicators as the mass fraction of fats, phosphates and chlorides, purification is "unsatisfactory" since it is in the range from - 0.8 to - 19.4% But, despite this, it is effective.
