【摘要】：城镇污泥的处理处置是城镇建设的一部分。随着城镇污水的增多,污泥的产量也不断增加,污泥的处理处置已成为城镇建设的一个难题。城镇污泥虽是污水处理后剩余的废弃物,但污泥中含有许多可供利用的资源,完全可以资源化利用。由于我国城镇污泥并没有得到很好的处置,这不仅带来大量的环境问题,更是对资源的浪费。因此城镇污泥的资源化利用势在必行,其不仅可以节约资源,还能很好地保护环境,这也是“两型社会”建设的内涵。本文以“两型社会”建设为背景,以人地协调理论、可持续发展理论和循环经济理论为指导,对我国城镇污泥的处置现状进行分析,发现存在的问题,然后对污泥资源化利用必要性和可行性进行论证,接着分析污泥资源利用的路径,选用熵值法和模糊综合评价法对其效益进行评价,最后提出污泥资源化利用的保障措施。论文的主要结论包括：(1)我国城镇污泥处置的存在的问题：一是城镇污泥处置的投资较低；二是技术和设备落后,管理不到位；三是城镇污泥处置率低,特别是污泥资源利用率很低。(2)城镇污泥必资源化利用是“两型社会”建设和经济发展模式的要求,城镇污泥资源化利用有技术的支撑和国家政策的支持,证明是可行的。(3)通过对目前城镇污泥处置进行分析,得到“两型社会”建设背景下城镇污泥资源化利用的路径为：污泥堆肥农用、污泥土地利用、污泥焚烧发电以及污泥建材化利用。(4)通过建立包括经济、社会和环境效益的指标体系,运用熵值法和模糊综合评价法对城镇污泥资源利用路径的效益进行评价,得出在当前技术条件下污泥建材化利用为最佳路径。(5)最后从建立健全相关法律法规和管理机制、适度的保障和激励政策、建立费用补偿机制、加强人才培养和鼓励技术创新、加强宣传和舆论引导五个方面对城镇污泥资源化利用提供对策参考。
[Abstract]:The treatment and disposal of urban sludge is a part of urban construction. With the increase of urban sewage, sludge production is also increasing, the sludge treatment and disposal has become a difficult problem in urban construction. The urban sludge is remaining after sewage treatment of waste sludge, but contains many available resources, can resource use. Because of China's urban sludge has not been well disposed, which not only bring a lot of environmental problems, it is a waste of resources. Therefore, urbanization resource utilization of sludge is imperative, which can not only save resources, but also to protect the environment, which is also the connotation of "two type society" construction in this paper. With the background of "two type society" construction, taking man land coordination theory, sustainable development theory and the circulation economic theory and the status quo of China's urban sludge disposal were analyzed, found. Then, on sludge demonstrates the necessity and feasibility of using path analysis, then sludge resource utilization, evaluate the benefits of using entropy method and fuzzy comprehensive evaluation method, and finally puts forward the safeguard measures of sludge resource utilization. The main conclusions of this paper include: (1) the problems of China's urban sludge disposal: one is the urban sludge disposal investment is low; the two is the backward technology and equipment, management is not in place; three is the urban sludge disposal rate is low, especially the sludge resource utilization rate is very low. (2) have urban sludge resource utilization is the construction of "two oriented society" and the mode of economic development requirements. Urban sludge resource utilization technology support and the support of national policy, it is proved to be feasible. (3) through the analysis of the current urban sludge disposal, "urban sludge resources utilization two type society" construction background Use the path: sludge compost and sludge land use, power generation and sludge materials utilization of sludge incineration. (4) through the establishment of index system including economic, social and environmental benefits, to evaluate the urban sludge resource utilization efficiency of path using entropy method and fuzzy comprehensive evaluation method, obtained in the current technical conditions of sludge utilization of building materials for the best path. (5) finally from establishing and perfecting relevant laws and regulations and management mechanism, appropriate protection and incentive policies, establish compensation mechanism, strengthen personnel training and encourage technological innovation, strengthen five aspects to guide urban sludge resource utilization to provide countermeasures for reference propaganda and public opinion.
