Compost and planting system and method thereof

A compost and planting system, comprising:

• an air-water source arrangement, which has a liquid inlet, a liquid outlet and an air-water flowing chamber defined between said liquid inlet and said liquid outlet, comprising a bottom wall, a base wall and a plurality of tubular circulation hubs spacedly supported between said bottom wall and said base wall in said air-water flowing chamber, each of said plurality of circulation hubs having an upper opening end, a lower opening end, a hub cavity defined between said upper opening end and said lower opening end, and a plurality of liquid slots spacedly formed around said lower opening end communicating said hub cavity with said air-water flowing chamber;
• a composter arrangement comprising a composting container, which is mounted on said air-water source arrangement and configured for containing disposed organic waste for composting, having a filtering bottom positioned on at least a first portion of said base wall of said air-water source arrangement;
• and
• a planting arrangement comprising at least one soil tub, which mounted on said air-water source arrangement, having a bottom opening communicating with said hub cavities of said circulation hubs of said air-water source arrangement, wherein said at least one soil tub is configured for filling a planting soil therein while said planting soil also fills in said hub cavities positioned below said bottom opening of said soil tub;
• thereby a sewage produced from said organic waste contained in said composting container during decomposition is drained into said circulation hubs positioned below said filtering bottom of said composter arrangement and flows into said air-water flowing chamber of said air-water source arrangement through said liquid slots of said circulation hubs, and that a liquid is fed into said air-water flowing chamber of said air-water source arrangement via said liquid inlet to carry the sewage to flow in a lower portion of said air-water flowing chamber to form a lower liquid layer while an upper portion of said air-water flowing chamber is maintained to have a flow of air to form an upper air layer, such that said liquid in the lower portion of said air-water flowing chamber enters said circulation hubs through said liquid slots thereof to be absorbed by the planting soil contained in said circulation hubs positioned below said soil tub.
