ABSTRACT:
A solid and liquid waste disposal and treatment plant, and a method for operating the plant is described. Solid waste received in the plant is incinerated in one or more rotary drums disposed in a closed furnace chamber. The solid waste incineration takes place under an oxygen deficiency to liberate heat energy and generate a combustible gas. A pyrolyzation or carbonization drum is also disposed in the furnace chamber and heated with the liberated heat energy. Organic matter, primarily organic sewage sludge is placed into the pyrolyzation drum and carbonized to produce coal. The coal is placed into a two-stage coal filter for the filtration of incoming sewage. The second stage of the coal filter utilizes coal activated within the plant for the removal of both particulate and dissolved contaminants so that the effluent from the filter comprises usable water. The combustible gas is cracked in a cracking unit to form short chain hydrocarbons and the gas is utilized in an internal or external combustion engine, a furnace or liquefied for subsequent use. Hot exhaust gases generated in the furnace and in the combustion engine are cooled by directing it through suitable heat exchangers or over wet solid waste or wet, sludge saturated filter coal to dry them while cooling the exhaust gas and to further cleanse the exhaust gas of pollutants for its discharge to the atmosphere. Sludge saturated filter coal is regenerated in the furnace by carbonizing organic sludge adhering to the filter coal or it may be incinerated with solid waste.
