High-capacity bio-block aeration system for stimulating enhanced bio-activity in aerobic wastewater treatment processes

摘要

This invention relates to the aeration of relatively large volumes of wastewater using an improved high-capacity aeration system to stimulate enhanced bio-activity. An air delivery system is provided to deliver oxygen to a body of wastewater beneath a large main processing float and a plurality of smaller bio-block floats positioned in proximity to the large main float to sustain biological media submerged beneath the floats. The bio-block floats are positioned relative to the main float so that the treatment capacity of the system can be increased without using additional, more costly, large processing floats. Moreover, the bio-block floats are made smaller relative to the main float so that the system can be easily and inexpensively transported using readily available standard-sized trucks.
