| 摘 要： | 以沈阳北部污水处理厂污泥为研究对象 ,开展了污泥土地利用对农作物及土壤环境影响的研究 .结果表明 ,污泥土地利用可提高土壤中N、P及有机质含量 .污泥用量为 2 2 .5t·hm-2 和 45t·hm-2 时有利于作物生长发育 ,使水稻生物量与对照相比分别增加了 11.48%、11.83%.污泥施用量只要控制在 45t·hm-2以内 ,污泥中的重金属不会对土壤、农产品质量及地下水产生不良的影响 .

| Abstract: | Effects of land utilization of sewage sludge on crops and soil environment were studied using sewage sludge from the Northern Shenyang Plant of Wastewater Treatment. The results showed that contents of nitrogen, phosphorus and organic matter in the soil were increased after the utilization of sewage sludge, thus being advantageous to growth and development of crops. The biomass of rice after having applied 22.5 and 45 t.hm-2 of sewage sludge was increased by 11.48%-11.83% compared with the control. There was no evident harmful effect of heavy methals from sewage sludge on quality of soil environment, agricultural products and underground water when the application of sewage sludge was controlled within the range of 45 t.hm-2. |
