Researcher of China environmental academy of sciences Zhao ZhangYuan: It is not the best way to deal with rubbish to burn
The intersection of reporter and YongFeng Feng it is reported recently, a lot of city plan, build rubbish, burn facility, in order to dispel the pollution brought in landfill of rubbish, solve troubling " rubbish encircles a city " Question. For this reason, researcher of China environmental academy of sciences Zhao ZhangYuan points out, the rubbish is burnt actually pollution is shifted, not only can not solve the problem, may bring more serious environmental calamity. Zhao ZhangYuan analyzes, " the material is not killed " It is basic physics general knowledge, it is unable to " eliminate " the rubbish that the rubbish is burnt ,But transform the pollutant into the gaseous state by the solid state, its weight and volume have not not merely shrunk, will also increase. Burning the waste gas produced is discharged into the atmosphere of high altitude, though eyes are not easy to see, but the pollutant in the atmosphere circulates each other, can circle round to every area through the convection. Except that it will be reduced to some extent as time passes that it is apt to degrade the material partly, most poisonous organic matter and heavy metal will also come back to mankind's side sooner or later; To some degree, the gaseous material enters the human body more easily, and accumulate in the body, cause danger. Zhao ZhangYuan says, deals with the rubbish by burning, value the rubbish and burn the value to the supply of electric power in the reason why some places. However, the calorific value of some rubbish such as kitchen cabinet rubbish is not high, and need to promote combustion while burning, if use the heat that flammable thing burns in the present rubbish for generating electricity, need to add more than 20% of the auxiliary fuel, and need to consume a large amount of oxygen. Moreover, flammable rubbish mostly can have value, burning loses the rubbish and actually wastes resources. Zhao ZhangYuan thinks, the garbage disposal best way is rubbish classification and comprehensive utilization, this needs to pay close attention to " Citizen's participation " ,Improve the whole people's garbage disposal consciousness.
