摘要
上海的砖瓦厂生产工艺设备比较先进,使用的燃料大部分是工业副产品,含氟量低,对烟气余热又都进行了重复利用,其中的含氟废气部分被砖坯所吸收或吸附,所以它们对周围农田生态系统的影响不严重。但是氯化物是一种可以在环境中不断积累和转移的污染物,所以砖瓦厂仍应注意生产工艺的改革,加强环境监测工作,以确保农田的生态平衡。
Because of the facts that the technologies and facilities arc advanced in the brick production, most fuels used arc by-product with low fluoride content, the surplus heat from chimney is recycled, fluoride in waste air was partly absorbed or adsorbed by bricks, the effect of fluoride pollution of brick-field on the agricultural environment in the suburbs of Slianghai is not serious. However, Since fluoride may be continuously accumulated and transfcrcd in the environment, attention should be paid to the technological reformation of the brick-field, and the environmental monitoring should be enforced in order to protect the agricultural environment from fluoride pollution.
