摘 要：

The 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.

摘 要 附 图：

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 主权项：
