城市污水污泥生态稳定新技术

城市污水污泥作为污水处理的副产物，因其有臭味，含病原菌、寄生虫卵、重金属和某些有毒有机物等，越来越成为环境新问题，通常采用的土地填埋、农田利用、海洋排放及焚烧等污泥处置方法，却因为环境及经济因素而受到限制，因此，人们不断研发污泥处理新技术，人工湿地处理城市污水污泥技术以自然能源为驱动力，利用生物能源去除污泥中污染物，能耗少、无害化、高效率、易管理，符合我国的基本国情。

The New Technology of Ecological Stabilization for Sewage Sludge Treatment

As the by-product of wastewater treatment,municipal sewage sludge has increasingly become a new environmental problem,because of it's unpleasant smell,containing pathogens,parasites eggs,toxic heavy metals and organic compounds.Limited by environmental and economic factors,landfill,land application,marine discharge and incineration are usually restricted.Therefore,people are constantly developing new technologies for sludge treatment.The new technology of artificial wetlands treatment for municipla sewage sludge takes natural energy as it's main driving force,it uses bio-energy to remove pollutants from the sludge,which has low energy consumption,no danger for environment and high efficiency.This technology conforms to China's basic national conditions.
