Abstract A method for reclaiming variegated wastes such as garbage, sewage, and saline dredging spoils includes the primary step of desalinization of the dredging spoils by draining off the salty water. The garbage is cleaned of non-organic material, and the remaining material is shredded and reduced to a slurry. The slurry is mixed with raw or primarily treated sewage and the treated spoils, and pumped through a pipe-line to a treatment and reclamation area. In transit, the clay particles within the dredging spoils adsorb suspended solids and dissolved organic and inorganic contaminants, aided by the agitation of the transit. At the treatment area, the solids are removed by settling, and composted to form rich agricultural soil. The water is treated with biological and/or chemical means until suitable for desired use or may be used directly for irrigation purposes or the like.
A method for reclaiming waste products and dredging spoils, comprising the steps of: desalinating clay-bearing dredging spoils by placing the spoils in corrals, segregating the sea water from the sediment, and draining away the sea water, mixing said desalinated dredging spoils with sewage to form a slurry, piping said slurry to a disposal site and mixing said slurry during piping to effect exposure and adsorption of contaminants of said primary sewage to the clay particles of said dredging spoils, separating said slurry into solids and waste water, said solids including said contaminants adsorbed to said clay particles, and composting said solids remaining after separation of said slurry.
Claim 2
Dependent Claim
33 words
The method of claim 1, further including the step of shredding solid organic waste and mixing said shredded waste with said primary sewage and said desalinated dredging spoils prior to said transporting step.
Claim 3
Dependent Claim
24 words
The method of claim 1, wherein said waste water separated from said slurry is treated in algal rearing ponds to remove nitrate substances therefrom.
Claim 4
Dependent Claim
32 words
The method of claim 1, further including the step of injecting air into the slurry during piping to provide sufficient oxygen to maintain the bacteria in said slurry in a viable condition.
