摘　　要：在钢铁生产过程中产生大量的废渣、排放大量的CO2;大气中CO2气体的增多造成温室效应,使得全球气温升高。转炉渣中含有对藻类植物生长有益的营养元素,如果可以利用转炉渣作为营养源来增殖藻类固定CO2,既利用了钢渣,又能够减少大气中的CO2。研究用1号炉渣和2号转炉渣对于扁胞藻进行了一级培养和对螺旋藻进行了一级、二级培养。结果表明,加入转炉渣可以增殖扁胞藻和螺旋藻;在螺旋藻的一级培养中,1号转炉渣的最佳加入量为0.4g/L,2号转炉渣为0.06g/L;同时要考虑到加入转炉渣后透光度对海藻生长的影响。It could produce lots of waste slag and CO2 during iron-steelmaking process,and the increase of CO2 content in the atmosphere makes greenhouse effect and causes the globe temperature rise.There are some nutrition elements for proliferation of which algae in slags.It not only utilizes slags,but also reduce the content of CO2 in the atmosphere to use slag as the nutrient source to proliferate algae and fix CO2.The first stag cultivation of platymonas and first and second stag cultivation of spirulina by No.1and No.2converter slag are studied.The results show that converter slag could proliferate algae.The optimum addition amount is 0.4g/L and 0.06g/L for No.1converter slag and No.2converter slag respectively during the first stage cultivation of spirulina.Meanwhile,the transmittance of the medium after adding slags is taken into consideration.
