System for decomposition of organic compounds and’method of operation thereof

Abstract

The present invention relates to an aerobic system for decomposition of aqueous organic waste. The system has at least a first processing container including sides, the container having a capacity from 100m3 to 30,000m3 and provided with an upper opening with an area from 100m2 to 20,000m , a substantially horizontal floor with an area from 100m2 to 10,000m2 and a depth from lm to 3m, 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, 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 0.5m and a depth from 0.5m to 1m, and a ventilating pipe extending above the mouth, the ventilating pipe having a multiplicity of apertures, and a pump connected to the pipe and arranged to provide a supply of a gas comprising 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.
