火电厂粉煤灰的农业利用,是利于工厂环保和促进农业增产改土的新课题。自1978年起,湖北、浙江、山东等地的有关单位进行了磁性粉煤灰的改土协作研究,1983年通过了水电部组织的部级科技成果鉴定。试验表明:粉煤灰经过一定强度的磁场处理,变为磁化灰,有改良土壤、增加农作物产量的综合作用,与传统的大用灰量相比,具有更佳的改土增产效益。本文是1982、83年二种环境三处的试验,讨论如下:
The utilization of fly ash in thermal power plants is a new task that is conducive to the environmental protection of the plant and the promotion of agricultural production and improvement of soil. Since 1978, relevant units in Hubei, Zhejiang and Shandong conducted collaborative research on ameliorating magnetic fly ash. In 1983, they passed ministerial-level scientific and technological achievements appraisal organized by the Ministry of Energy and Electricity. Experiments show that the fly ash has a certain strength of the magnetic field treatment, into a magnetized ash, improve the soil, increase the combined effect of crop production, compared with the traditional large amount of ash, with better soil improvement yield. This article is 1982, 83 two kinds of environment three experiments, the discussion is as follows:
