Abstract
Изобретение относитс к биологической очистке сточных вод, содержащих органические загр знени . Цель изобретени - снижение материалоемкости и у дешевление конструкции при сохранении эксплуатационных показателей биофильтра. Биофильтр 1 разделен по высоте на зоны 3. Высота каждой зоны определ етс конструктивными размерами загрузочного материала. Удельна поверхность загрузки каждой зоны состоит из одного или нескольких слоев загрузочного материала, имеющего одинаковые конструктивные параметры , уменьшаетс в направлении сверху вниз, пропорционально изъ тию загр знений во всей рабочей высоте биофильтра. Удельна поверхность загрузочного материала каждой зоны определ етс по формуле SV Lfq (1 - |-hi) . р; где Si - удельна поверхность загрузки i-й зоны,.

Между зонами регул рного плоскостного загрузочного материала устраиваютс перераспределители воды 4. Зонна загрузка биофильтра позвол ет рационально использовать загрузочный материал. 1 з.п. ф-лы, 3 ил. а $ СП 4 елThe invention relates to the biological treatment of waste water containing organic pollutants. The purpose of the invention is to reduce material consumption and reduce the cost of construction while maintaining the performance indicators of the biofilter. The biofilter 1 is divided by height into zones 3. The height of each zone is determined by the design dimensions of the feed material. The specific loading surface of each zone consists of one or several layers of a loading material having the same structural parameters, decreasing from top to bottom in proportion to the removal of contaminants in the entire working height of the biofilter. The specific surface area of the loading material of each zone is determined by the formula SV Lfq (1 - | -hi). R; where Si is the specific surface of the loading of the i-th zone. Lf-BOD coming to the wastewater treatment, mg / l; E - the overall effect of cleaning and, dol unit; H is the total working loading height of the biofilter m ;. hi-distance from the top of the upper zone to the middle of the i-th zone, m; F is the BUKf load at which the desired cleaning effect is achieved (E); g in 1 day; q - hydraulic load in 1 day (numerically equal to volumetric hydraulic load, in 1 day). Water distributors 4 are arranged between the zones of a regular planar feed material. Zonal loading of the biofilter allows efficient use of the feed material. 1 hp f-ly, 3 ill. and $ SP 4 ate
