INDUSTRIAL SYSTEM FOR BIOLOGICAL DEEP PURIFYING OF SEWAGE

摘要

Uses1 biological wastewater treatment by biofiltration. SUMMARY OF THE INVENTION The biofilter contains a load which is made of volumetric frame modules installed with the possibility of joining elements in both vertical and horizontal planes. The module case is made of beams, struts and bottom, and the porous-hollow elements are in the form of a rectangular prism. with through holes and grooved channels along the perimeter. In the self-supporting structure of the module, the transverse axes of the vertical holes are offset relative to the transverse axes of the trough-like channels, and the thickness of the bridges between the holes is equal to their diameter, 5 or more
