sewage water purification engineering. SUBSTANCE: plant has rectangular casing in the form of tank incorporating primary sediment bowl, aeration bowl with attached microflora carrier divided by vertical partitions into stages, aeration system, secondary sediment bowl, active- mud circulating system, and unit for bactericide treatment of purified water with ultraviolet rays. Attached microflora carrier is built up of flat screens mounted crosswise of water flow throughout its entire width; primary sediment bowl is divided through height into two parts by means of partitions and its bottom part is provided, in addition, with aeration system; plant proper is equipped with additional equalizing tank accommodating aeration system and aerobic stabilizer vessel with aeration system. EFFECT: improved efficiency and reduced metal input of plant. 1 dwg |
