北京朝阳区有不少大型工厂,每天有许多带着大量余热的冷却水,白白地流失了。能不能将这些余热利用起来,造福于民呢?朝阳区水产局的同志用一年多的时间,进行了调查、宣传和组织工作。在他们的努力下,朝阳区已有25家工厂可以用余热水养鱼了,养殖面积可达5万米~2。如果用低指标计,每平方米每年可产鱼40斤的话,每年就可产200万斤鱼。实际上有余热水的工厂远不止此数,可见潜力还很大。 There are many large-scale factories in Chaoyang District, Beijing. There are many daily cooling water with a lot of waste heat, which is completely lost. Can these waste heat be used to benefit the people? Chaoyang District Bureau of Fisheries comrades in more than a year’s time, conducted a survey, advocacy and organizational work. In their efforts, 25 factories in Chaoyang District can fish with waste heat water, and their breeding area can reach 50,000 meters ~ 2. If you use low indicators, per square meter per year can produce 40 pounds of fish, then produce 2 million pounds per year fish. In fact there are far more than the number of factories hot water, showing great potential.
