【摘要】：随着城市建设和环境保护事业的不断发展,给水厂所排出的生产废水对环境的污染越来越引起人们的关注。给水厂的生产废水主要指沉淀池排泥水和滤池反冲洗废水,这些废水所产生的污泥主要是无机泥沙,其悬浮物含量远远超过国家标准。如果这些废水不加以处理,直接排入水体或下水道,不仅污染受纳水体,而且会造成水资源的大量浪费,对水环境造成较大的影响。在目前水资源严重紧张,水环境污染日趋严重的情况下,建设给水厂的污泥处理工程,实现给水厂“零排放”,保护水资源尤为重要。本论文研究的课题依托于“珠海市拱北水厂污泥脱水处理系统工艺”,结合该水厂运行管理的规律以及基础设施的约束条件,对给水厂的污水、污泥的性质进行分析研究,从而确定适于该水厂的污泥处理工艺流程。通过对污泥量及污水量的合理计算,经分析比较,提出并确定了污泥、污水回收调节池和浓缩池的处理型式和设计参数。从技术指标、综合经济指标等方面,比较污泥脱水设备的性能,确定脱水设备的型式和设计参数。在此基础上,确定了适合该水厂污泥处置的最终实施方法。同时,为了更加系统完善,本文还对该工艺的污泥处理自动化控制系统进行研究设计。最后,对该水厂的污泥脱水处理工艺进行了全面的技术经济研究,从而为给水厂的污水及污泥处理工艺设计提供有意义的参考。
[Abstract]:With the continuous development of urban construction and environmental protection, people pay more and more attention to the pollution of production wastewater discharged from water plants. The production wastewater in the water plant mainly refers to the sludge water in the sedimentation tank and the backwashing wastewater from the filter pond. The sludge produced by these wastewater is mainly inorganic sediment, and the content of the suspended matter is far beyond the country. If the wastewater is not treated and discharged directly into the water body or sewer, it not only pollutes the receiving water, but also causes a large waste of water resources and has a great influence on the water environment. Under the condition of serious water resources and water environment pollution, the construction of sludge treatment project of water supply plant is realized to the water plant. "Zero discharge" is particularly important to protect water resources. The subject of this paper is based on the process of sludge dewatering system in Gongbei water plant of Zhuhai city. Combining the rules of operation and management of the water plant and the constraints of infrastructure, the properties of sewage and sludge in the water plant are analyzed and studied so as to determine the sludge suitable for the water plant. Through the reasonable calculation of sludge quantity and sewage quantity, through analysis and comparison, the treatment type and design parameters of sludge, sewage recovery regulating pool and concentration pool are put forward and determined. From the technical index and comprehensive economic index, the sexual energy of the sludge dewatering equipment is compared, and the type and design parameters of the dewatering equipment are determined. On the basis of this, the final implementation method suitable for the sludge disposal of the water plant is determined. At the same time, in order to improve the system, this paper also studies and designs the automatic control system of the sludge treatment in this process. Finally, a comprehensive technical and economic study on the sludge dewatering process of the water plant is carried out for the sewage and sludge of the water plant. The technical design provides a meaningful reference.
