The issues of technical support for the process of wastewater clarification during the treatment of wastewater from industrial enterprises on local technological equipment with a capacity of 1-10 m3/hour are considered. The presented technological scheme and equipment, research in the circulating water supply system of the engine testing shop area, allows for wastewater treatment along various technological lines, in several modes and parameters with different contamination compositions and constant monitoring of the treated wastewater, according to the main indicators. Wastewater clarification is carried out using a technological scheme, including pressure electroflotocoagulation in devices for local wastewater treatment using several technological lines and modes. The incoming processing water is collected in a receiving collector, undergoing processing in a wastewater treatment apparatus, and is processed in several modes along its own technological lines. Water samples are monitored (sampled) at all stages of clarification. To intensify the clarification process, a reaction pipe is installed in the center of the apparatus. The use of a saturator installed outside the apparatus helps to increase the degree of intensification of clarified waters. The use of local equipment in recycling water supply systems aimed at wastewater clarification is based on a new set of design and technological solutions that provide a greater degree of wastewater clarification. Further mathematical processing of the obtained results makes it possible to optimize the clarification process itself, reduce water treatment costs and ensure the environmental safety of water bodies. Subject: patterns and features of the process of wastewater clarification in devices for local wastewater treatment of industrial enterprises.
