FIELD: equipment for biological purification of sewage water. ^ SUBSTANCE: apparatus for biological purification of sewage water has housing 1 incorporating balancing tank 4, aeration tank 8 divided by means of vertical partition walls 9 into steps furnished with aeration systems 10 and attached microflora carriers 11, secondary settler 12 with silt sedimentation hopper-accumulator 13, silt sedimentation discharge branch pipe 14, and unit 15 for bactericidal treatment of water. Housing 1 is furnished on the outside with thermal insulation 2 and is divided by means of vertical partition walls 3 into two reservoirs. First of reservoirs is balancing tank 4 having volume equal to at least 4-6 volumes of aeration tank and equipped with two vertical partition walls 5. Second reservoir 6 is equipped with system 7 for maintaining constant temperature and moisture content. Second reservoir 6 incorporates aeration tank 8, secondary settler 12 with silt sedimentation hopper-accumulator 13, branch pipe 14 for discharge of said silt, and unit 15 for bactericidal treatment of water. ^ EFFECT: reduced sizes, metal usage and manufacture costs of apparatus. ^ 1 dwg, 1 ex |
