Refuse landfill waste disposal method

Abstract

The invention discloses a refuse landfill waste disposal method which comprises the following steps: a, mixing inorganic oxide grains, phosphate solution and waste to form a first mixture; b, mixing the first mixture with an additive to form a second mixture; c, adding water in the second mixture to form a fluidity mixture; d, homogenizing the fluidity mixture and sending the homogenized fluiditymixture to an assigned site through a pump; and e, solidifying the fluidity mixture pumped to the assigned site. The refuse landfill waste disposal method is characterized in that the inorganic oxidegrains are formed by sending inorganic oxide into a plasma furnace, roasting the inorganic oxide and then cooling the roasted inorganic oxide; the temperature applied to the plasma furnace is increased from the first temperature with the rate of 10 DEG C per minute; and the second temperature is reached through roasting for 20 minutes to 40 minutes from the first temperature, and then, roasting iscarried out for 40 minutes to 120 minutes at the constant temperature of the second temperature. With adoption of the refuse landfill waste disposal method, the fluidity of the mixture can be improved, so that the waste is smoothly transported to a refuse landfill where a vehicle can not arrive through the pump and a pipeline and then is solidified.

Description

technical field [0001] The invention provides a method for treating waste in a landfill site, belonging to the technical field of waste treatment. Background technique [0002] Since a considerable amount of non-recyclable waste is generated every day, a considerable expense must be spent annually to dispose of the waste. However, when hazardous waste and radioactive waste are piled up, care must be taken to prevent the waste from destabilizing and causing leakage; non-hazardous waste can be recycled and / or biodegraded. In the prior art, garbage sites are usually used to stack non-recyclable and non-biodegradable wastes, but land resources are becoming more and more scarce, and there are fewer and fewer places for stacking garbage accessible to vehicles. [0003] In order to overcome the above problems, the prior art provides a technology that can transport waste through pumps and pipelines to landfills that vehicles cannot reach, but the oxide powder provided for the above...

In the prior art, garbage sites are usually used to stack non-recyclable and non-biodegradable wastes, but land resources are becoming more and more scarce, and there are fewer and fewer places for stacking garbage that can be reached by vehicles

[0003] In order to overcome the above problems, the prior art provides a technology that can transport waste through pumps and pipelines to landfills that vehicles cannot reach, but the oxide powder provided for the above method has poor fluidity of the mixture
