【摘要】：随着改革开放的深入，城市用水污染问题日益显现。哈尔滨市人民长期饮用的松花江水受到的污染情况较重，水体常年达不到饮用标准，人民生产生活受到严重威胁。1999年底由市水务局牵头，专家论证提出兴建磨盘山水库，异地取水，早日彻底解决哈尔滨市人民吃水的问题。磨盘山水库供水工程是以城市供水为主，兼顾下游防洪灌溉的大型引水工程。磨盘山净水厂采用机械絮凝、斜管沉淀与翻板阀滤池过滤的常规工艺组合，能够提供满足现行水质指标要求的城市饮用水。本文对当前磨盘山净水厂水工艺处理中存在的问题进行了阐述。同时，提供了针对常规工艺处理各个流程的优化措施，进一步优化了常规水处理工艺效果。在混凝阶段，对混凝药剂进行了并优化了部分工艺参数，节省了混凝药剂的用量并达到了更好的效果。在沉淀阶段，通过排泥控制方式的优化及部分沉淀工艺参数的优化，使沉淀效果有所提升。在过滤阶段，得到了对滤池自动化清洗的必要性和存在的问题进行了论述，，结合实际对现有的自动清洗方式存在的问题进行了分析和归类，总结并提出了优化意见和具体实施方案。基于自动化技术，在重新安排清洗滤池的队列的基础上，提出了一种并行清洗滤池的方案，改善了之前串行清洗滤池出现的高耗时的缺点，提高了滤池清洗效率，从而提升水厂的经济效益和社会效益，为百姓谋福祉。通过优化前后水厂测得的水质指标对比，确定了整个优化过程的优化效果；通过优化前后经济效益分析对比，确定了整个优化过程在实际生产中的可行性。本文不仅阐述了磨盘山水厂工艺优化过程，也为后续其它水厂工艺优化过程起到了指导作用。
[Abstract]:With the deepening of reform and opening-up, the problem of city water pollution become more and more obvious. The pollution situation of Harbin City People's long-term drinking of Songhua River is heavier, not up to the standard of drinking water throughout the year, production and life of the people is a serious threat to.1999 by the end of the Municipal Water Affairs Bureau led experts proposed the construction of Mopanshan Reservoir, off-site water, completely solve the Harbin City People's problems as early as possible. The draft of Mopanshan Reservoir water supply project in city water supply, taking into account the large water diversion projects flood irrigation downstream. Mopanshan by mechanical flocculation, inclined tube sedimentation process in combination with conventional valve filter, to satisfy the requirements of the current water quality index of city drinking water.
This paper discusses on the current Mopanshan water treatment process in the problem. At the same time, provides the optimization measures aiming at each process the conventional treatment process, optimizing the effect of conventional water treatment. In the coagulation stage, and the optimization of some parameters on the coagulant, save the coagulant the dosage and achieved better results. In settling stage, based on the optimal control mode and part of the mud sedimentation process parameters, the precipitation effect improved. In the filtering phase obtained on filter automatic cleaning the necessity and existing problems are discussed, combined with the existence of the existing automatic cleaning method the actual problems are analyzed and classified, summarized and put forward the optimization suggestion and specific implementation plan. Based on automation technology, based on the re arrangement of cleaning filter queue, is presented A parallel cleaning filter scheme improves the shortcoming of high consumption time before the serial cleaning filter, improves the efficiency of filter cleaning, and improves the economic and social benefits of the waterworks, and benefits for the common people.
Through the comparison of water quality indicators before and after optimization of the measured water, determine the optimization effect of the entire optimization process; through the analysis and comparison of before and after optimization of economic benefits, to determine the feasibility of the optimization process in the actual production. This paper not only elaborates the Mopanshan plant process optimization process, but also for subsequent water treatment process optimization process to guide role.
