摘要
分析了北京市污水处理厂污泥的产量与性质,在考虑北京市土地资源状况情况下,论述说明污泥土地利用是北京市污泥处置的优化选择,并初步预测了污泥肥料土地利用的效益.预测结果表明:如充分利用污泥有机肥料,不仅可以获取每年1.0亿元的可观经济效益,而且可大幅降低农业面源污染负荷,具有显著的环境和社会效益.
Based on the analysis of sludge＇s quality, quantity and Beijing＇s land quality status, the perspective of land application of sewage sludge is presented. It would bring us a notable benefit to both the environment and the society. It indicates that we could receive one hundred million yuan per year and alleviate about 30 percent of nitrogen load in agriculture non-point source pollution by applying one million tons of sludge manures to the farmland. In conclusion, we suggest that it is the best choice for Beijing to apply the sewage sludge to the land.
