摘要
城市污水处理厂污泥和生活垃圾及粉煤灰富含作物生长所需的氮、磷、钾等营养成份和大量有机质 ,可以充分利用到农业生产中 ,将污泥、垃圾和粉煤灰按 4∶5∶1配比堆肥发酵 ,并根据地域特点研制水稻和甘蔗有机复合肥。田间试验表明 ,制成的有机复合肥对水稻和甘蔗均有较好的增产效果 ,并可以改善土壤结构 ,提高土壤的肥力。
Sludge discharged from urban wastewater treatment plant, domestic refuses and fly ash of coal combustion contain necessary elements of crop growth such as N, P, K and other nutrients and organic humus. Organic complex manure could be made by fermented compost of mixed sludge, refuse and fly ash in proportion by weight of 4∶5∶1. It will be adapted to specific for certain crops. The field experimental data show favorable results both for rice and sugar cane fields. Besides the fertility and the structure of the soil can be improved.
