Abstract

The basics of wastewater sampling at wastewater treatment plants for the correct analysis of the operation of the facilities are presented.

It is noted that the correct calculation of the sampling time is important for assessing the operation of structures at the mechanical and biological stages. The main factor that significantly affects the final result when performing calculations is fluctuations in the quantitative and qualitative characteristics of wastewater, which is due to the unevenness of water consumption by the population and industrial enterprises.

Calculating the biological stage of wastewater treatment, it is always necessary to take into account the distribution of the load on each aeration tank by the amount of wastewater and recirculated activated sludge, as well as the regime of operation of the aeration tank.

It was concluded that correct sampling and do a schedule of laboratory control, graphic display of the place and time of sampling excludes the possibility of errors, allows you to evaluate the operation of mechanical and biological treatment facilities, determine the efficiency of the equipment, and also determine the necessary of changing the operating mode, debugging the work, or performing a deeper analysis of the inefficiency of work.
