用煤渣、黑液生产硅肥

Manufacture of Silicate Fertilizer from Coal Ash and Wastewater

介绍了一种新的硅肥生产法,用该法生产的硅肥有效硅含量达25％～30％,经田间试验,增产效果明显,每吨成本只需150元左右,生产硅肥的主要原料为工业废渣及废液,其不仅具有较好的经济效益,而且可大大减少工业污染,更具有良好的环境和社会效益。

In this paper, we introduced the manufacture of silicate fertilizer from coal ash and wastewater by using the solid-state catalyst. The fertilizer contained available silicon of 25%-30% , the cost of it lows 150 yuans per ton, and the fertilizer increased the yield of rice and other crops strikingly.
