Technical Field
The invention belongs to the technical field of environmental protection, and relates to disposal of scrapped mercury-containing lamp tubes.
Background
At present, the mercury content of a T12 mercury-containing lamp tube with the tube diameter of 36mm in China is about 25-45 mg; a T5 mercury-containing lamp tube with a tube diameter of 16mm contains about 20mg of mercury; a compact mercury-containing lamp tube with a tube diameter of 10mm contains about 10mg of mercury. About 9 hundred million mercury-containing lamp tubes are produced in recent years in China, and the total mercury content in the mercury-containing lamp tubes produced in China every year is about 27t according to the average mercury content of 30mg per lamp tube.
The scrapped lamp tubes are discarded at will or mixed in a large amount in household garbage, so that the broken lamp tubes are extremely easy to diffuse mercury, and the health of residents is seriously endangered. 360 tons of water can be contaminated with 1mg of mercury. Once in the human body, mercury rapidly diffuses and accumulates in the kidney, chest, and other tissues and organs. The mercury-containing wastewater is discharged into a water body, and both metallic mercury and inorganic mercury can be converted into methyl mercury by bacteria, so that the mercury-containing wastewater can quickly enter cells and easily pass through a blood brain barrier to destroy nerve cells. Therefore, mercury, if recovered and disposed improperly, can pose a significant environmental hazard.
The disposal method of the mercury-containing lamp tube mainly comprises an incineration method and a recycling method at present, wherein the incineration method can cause the gasification of mercury in the mercury-containing lamp tube and easily cause secondary pollution; the recycling method has the advantages that the demand on the mercury-containing lamp tube is large, the early construction investment is large, the operation cost is high, if no sufficient quantity of waste mercury-containing lamp tubes exist, the sufficient profit cannot be ensured, and the feasibility cannot be realized.
