浅谈中国城市污泥的处置

On the Disposal of Sewage Sludge

城市污水污泥的处置已成为目前环境科学研究领域中的重要问题。中国是一个经济基础较为薄弱、可耕地有限的农业大国,而污泥中富含植物生长必须的有机质、腐殖质和矿质元素,其土地利用能改善土壤的理化性质,提高农作物产量,减少污泥对环境的二次污染,从而实现污泥的资源化、无害化、稳定化和减量化处置目标。概述了当前城市污泥处置的几种方法及研究进展,并就中国污泥处理处置和综合利用提出了相关建议。

Disposal of municipal sewage sludge has become a scientific research in the field of environmental issues. China is a relatively weak economic base, a major agricultural country with limited arable land, while the sludge is rich in plant growth must be the organic matter, humus and mineral elements, and the land - use can improve the physical and chemical properties of soil to improve crop yields and reduce the sludge to the environment secondary pollution, in order to achieve the recycling of sludge, sound, stable and disposal reduction goal. An overview of the current municipal sewage sludge disposal methods and research progress, and sludge treatment and disposal in China and put forward relevant recommendations of the comprehensive utilization.
