用粉煤灰制作人工鱼礁,既可为工业废渣的综合利用增加一条新途径,又能解决人工鱼礁建设中的原材料缺乏问题,有明显的经济效益和社会效益。 国外对粉煤灰人工鱼礁的试验研究,始于七十年代。美国从1976年开始研究用粉煤灰及烟道除硫废渣两种电厂废弃物作为主要原料,制成小块实心人工鱼礁,于1980年9月首次投放500吨。日本于1983年利用粉煤灰掺和特殊混合物制成八角形中空巨型人工鱼礁,重 Producing artificial reefs with fly ash can not only add a new way for comprehensive utilization of industrial waste residue but also solve the problem of lack of raw materials in the construction of artificial reefs with obvious economic and social benefits. Abroad on the artificial reef fly ash experimental study began in the seventies. Since 1976, the United States started to study the use of fly ash and flue gas desulphurisation waste residue as the main raw material to make solid artificial reefs. In September 1980, the United States first put 500 tons of solid reefs. Japan in 1983, the use of fly ash mixed with a special mixture made of octagonal hollow giant artificial reef, heavy
