Compartmentalized facultative lagoon and method of creating and maintaining such a lagoon

摘要

Compartmentalization of contents of a facultative lagoon into two separate zones improves the economic efficiency of the lagoon for emission control by eliminating macroscopic mixing between the zones, while allowing odor-causing compounds from the anaerobic zone to pass into the aerobic zone. A physical barrier compartmentalizes or divides the lagoon contents into an upper aerobic zone and a lower anaerobic zone. Odor-causing compounds biologically convert within the aerobic zone into olfactorily inoffensive compounds that release into the atmosphere. An aeration device aerates the aerobic layer. Emission of hydrogen sulfide, ammonia, volatile acids, phenols and other odorous gases from anaerobic wastewater and manure lagoons or basins is reduced.
