【摘要】：城市污水处理是高能耗行业之一。对城市污水处理厂进行能耗分析,发挥污水处理厂巨大的节能潜力,提高污水处理厂的经济效益,是保障投资商活力的重要措施,同时也有利于缓冲社会能源日益紧张的局面。应从工艺选择,设备选用,污泥处理与处置方法选择等方面进行优化控制,节能降耗。在污水处理厂设计建设中,尽可能选择低能耗,高效率的工艺和设备；在污水处理厂的运行中,要大胆运用先进的技术,实现污水和污泥的资源化利用,那么污水处理才能逐渐向高效低能的方向发展,实现其社会效益。本文针对通辽污水处理厂的工艺改造及其节能降耗的进展,对主要工艺和设备进行比选,从经济效益和对社会环境的影响进行分析,选出最佳方案对污水处理厂提标改造。通过提高出水水质,不仅使出水达到国家一级A标准,并且能够实现再生水的回用,满足再生水回用水质的要求,可以作为再生水水源回用。对于工艺污水厂的提标改造的技术问题需要进一步的深入研究,本课题将工艺的提标改建为主线,并对经济、社会、环境效益展开讨论研究,最后提出适合可持续发展的指导性建议。污水处理厂对该区的经济发展和居民的生活质量有十分重要的意义,同时也抑制了对周边环境的污染。财务评价的结论是可行的。推荐方案的工艺流程具有运行成本低的优点,符合排放标准要求。综上所述,本文中通辽污水处理厂升级改造工程的建设,在经济上是合理的,在技术上是可行的。本课题的研究,可为污水厂的提标改造工作提出指导性的建议,也可以为新建污水厂提供新的设计思路,为缺水地区提供了新的用水战略,所以本课题具有一定的理论意义和实际应用价值。
[Abstract]:Urban sewage treatment is one of the high energy consumption industries. It is an important measure to ensure the vitality of investors to analyze the energy consumption of urban sewage treatment plants, to give full play to the huge energy saving potential of sewage treatment plants, and to improve the economic benefits of sewage treatment plants. At the same time, it is also beneficial to buffer the increasingly tense situation of social energy. We should optimize the control from the aspects of process selection, equipment selection, sludge treatment and disposal method selection, and save energy and reduce consumption. In the design and construction of sewage treatment plant, Choose low energy consumption and high efficiency processes and equipment as far as possible; in the operation of sewage treatment plants, we should boldly use advanced technologies to realize the reuse of sewage and sludge, and then sewage treatment can gradually develop towards a direction of high efficiency and low energy. Realize its social benefit. In view of the progress of technological transformation and energy saving and consumption reduction in Tongliao sewage treatment Plant, the main processes and equipments are compared and selected, and the economic benefits and impact on social environment are analyzed. By improving the effluent quality, not only can the effluent reach the first class A standard of the country, but also the reclaimed water can be reused to meet the requirements of the reused water quality. It can be used as a reclaimed water source. The technical problems of the upgrading and transformation of the process wastewater treatment plant need to be further studied. This subject takes the upgrading of the process as the main line, and the economic, social and environmental benefits are discussed and studied. Finally, some guiding suggestions for sustainable development are put forward. Sewage treatment plants are of great significance to the economic development of the region and the quality of life of the residents. At the same time, the pollution to the surrounding environment is restrained. The conclusion of financial evaluation is feasible. The process flow of the recommended scheme has the advantages of low operating cost and meets the requirements of emission standards. To sum up, the construction of upgrading and reforming project of Tongliao sewage treatment Plant in this paper is reasonable in economy and feasible in technology. It can also provide a new design idea for the new wastewater treatment plant and a new water use strategy for the lack of water area, so this subject has certain theoretical significance and practical application value.
