1. An aerobic system for decomposition of aqueous organic waste comprising:
(a) at least a first processing container including sides, the container having a capacity from 100 m3 to 30,000 m3 and provided with an upper opening with an area from 100 m2 to 20,000 m2, a substantially horizontal floor with an area from 100 m2 to 10,000 m2 and a depth from 1 m to 3 m; (b) an inlet for waste or waste water to be treated in the first processing container and an outlet for water treated in the first processing container; (c) at least one channel arranged at the floor having an upwardly opening mouth for collecting moulds, worms or worm-like living organisms, parasites and other sediments, the channel having a width less than 0.5 m and a depth from 0.5 m to 1 m; (d) a ventilating pipe extending above the mouth, the ventilating pipe having a multiplicity of apertures; and (e) a pump connected to the pipe and arranged to provide a supply of a gas comprising a mixture of compressed air with an additive selected from carbon dioxide, ammonia, sulphur dioxide, hydrogen sulphide, ozone and pure oxygen to the ventilating pipe to discharge a stream of air from the apertures into the water in use. |
