合理利用增氧机的二氧化碳减排效果研究

Study on CO_2 Emission Reduction from Rational Using of Aerator

依据2012年渔业部门的统计数据及前期研究成果,利用Oak Ridge National Laboratory(ORNL)提出的二氧化碳(CO2)排放量的计算方法,对我国池塘养殖增氧设备的二氧化碳排放量进行估算,计算和比较了增氧设备的合理利用带来的二氧化碳减排量,在此基础上对增氧设备的二氧化碳排放强度进行计算和分析。结果表明:2012年我国增氧设备的二氧化碳排放总量约为10 461.83万t,占当年二氧化碳排放总量的1.17%;利用射流式增氧机取代叶轮式增氧机,二氧化碳排放量可以减少2 323.92万t,占增氧设备排放总量的22.21%;相比单独使用叶轮式增氧机,将耕水机与叶轮式增氧机结合使用,二氧化碳排放量可减少2 061.17万t,占增氧设备排放总量的19.70%;池塘养殖增氧设备的二氧化碳排放强度为1.57 kg/美元,是美国二氧化碳排放强度的4.62倍。

Based on the 2012 statistical data of fisheries departments and preliminary research results,we adopted the calculating method of CO2 emissions proposed by Oak Ridge National Laboratory to estimated the carbon dioxide emissions of pond oxygen equipment,then,calculated and compared the reduction of carbon dioxide emission as a result of rational utilization of oxygen equipment,on this basis,calculated and analyzed carbon dioxide emissions intensity of oxygen equipment.The results showed thatthe total carbon dioxide emissions of oxygen equipment was 104.618 3 million tons,accounting for 1.17%of all the fields in 2012.With jet aerator instead of impeller aerator,the carbon dioxide emissions can be reduced 23.239 2 million tons,only take 22.21% part of all the oxygen equipment emissions.Compared to using impeller aerator alone,combining the farming water machine and impeller aerator can make the carbon dioxide emissions reduce 20.611 7 million tons,accounting for 19.70%of all the oxygen equipment emissions.The carbon dioxide emissions intensity of oxygen equipment is 1.57 kg/dollar,which is 4.62 times of U.S..
