【摘要】：本文首先概述了影响我国给水厂工艺发展的主要因素,并对给水厂工艺选择中应考虑的主要问题进行了论述。介绍了茂名滨海新区的发展概况,供水系统存在的问题,提出建设滨海新区给水厂工程建设的必要性;对给水厂的工程规模、水源选择、厂址选择、工艺选择进行了论证;并对给水厂进行了工艺设计和投资估算。建设茂名滨海新区是广东省和茂名市的重大发展战略,茂名滨海新区正处于大发展时机,但是目前区内的供水设施极不完善,制约了新区的发展。为了推动茂名滨海新区的快速发展,完善基础设施建设,亟需尽快实施茂名滨海新区给水厂工程。工程服务范围为:电城片区、博贺湾新城综合服务片区、博贺镇生活片区、博贺度假岛片区和博贺新港片区内的生活用水。近期设计规模为10万m3/d。水源采用河角水库及儒洞河,2种水源正常情况下水质良好;但河角水库水源会出现夏季高藻现象,儒洞河水源汛期时高浊并存在突发污染的情况。由于正常情况下原水水质良好,暂不设置深度处理工艺,仅预留用地;针对高藻现象,采用高锰酸钾预氧化工艺;设置粉末活性炭应急措施来应对突发污染事故。最终确定给水厂的总体处理工艺为“预处理+常规处理+消毒”工艺。给水厂净水处理构筑物包括:配水井、机械混合池、折板絮凝池、斜管沉淀池、后混凝池、V型滤池、清水池、吸水井、送水泵房、加氯间和加药间;污泥处理包括:排水池及回流泵池、排泥池及排泥泵池、污泥浓缩池和污泥脱水车间;附属建筑包括:综合办公楼、传达室及机修仓库。给水厂占地约60亩,估算总投资约17946.1万元。
[Abstract]:In this paper, the main factors influencing the process development of water supply plants in China are summarized, and the main problems that should be considered in the process selection of water supply plants are discussed. This paper introduces the general situation of the development of Maoming Binhai New area, the problems existing in the water supply system, puts forward the necessity of the construction of the water supply plant in the Binhai New area, and demonstrates the project scale, water source selection, site selection and process selection of the water supply plant. The process design and investment estimation of the water supply plant are also carried out. The construction of Maoming Binhai New area is an important development strategy of Guangdong Province and Maoming City. Maoming Binhai New area is in the great development opportunity, but the water supply facilities in Maoming Binhai New area are very imperfect, which restricts the development of the New area. In order to promote the rapid development of Maoming Binhai New area and improve the infrastructure construction, it is urgent to implement the water supply plant project of Maoming Binhai New area as soon as possible. The scope of service is: electric city area, Bohe Bay New City integrated service area, Bohe Town living area, Bohe holiday island area and Bohe Xingang area of domestic water. The recent design scale is 100000 m3 / d. The water sources of Hejiao Reservoir and Rutong River are of good water quality under normal conditions, but the water source of Hejiao Reservoir will appear the phenomenon of high algae in summer, and the water source of Rutong River will be high turbidity and sudden pollution in flood season. Due to the good quality of raw water under normal conditions, there is no advanced treatment process, only reserved land; in view of the phenomenon of high algae, potassium permanganate preoxidation process is adopted; the emergency measures of powdered activated carbon are set up to deal with sudden pollution accidents. Finally, the overall treatment process of water supply plant is "pretreatment routine treatment and disinfection" process. The water treatment structures of water treatment plant include: distribution well, mechanical mixing tank, folding plate flocculation tank, inclined tube sedimentation tank, back coagulation tank, V-type filter, clear water tank, water absorption well, water delivery pump room, chlorine adding room and dosing room; Sludge treatment includes: drain pool and backflow pump pool, sludge drain tank and sludge pump pool, sludge thickening tank and sludge dewatering workshop; ancillary buildings include: integrated office building, communication room and mechanical repair warehouse. Water plant covers an area of about 60 mu, estimated total investment of about 179.461 million yuan.
