毕业论文 课题名称：电路科技有限公司超纯水工艺运营 摘要 电路科技有限公司印制电路板样板、快件和小批量板的设计、制造服务商，主要生产高密度互连积层板高层快件和HDI刚挠板。在生产过程中要供应超纯水，受该公司邀请，对超纯水进行。 进水是采用市政自来水管网的供水或使用废水站回用水作为原水供水进水电导率小于300μs/cm [(25± 1)°C]。根据提供的资料，超纯水总需求量为51m3/h。其中，一期工程需求量为42m3/h。电阻率为~10MΩcm[(25± 1)°C]。本论文主要讲述运行管理过程中预处理阶段、反渗透阶段和EDI阶段的工作原理与作用、问题分析以及解决措施等。 关键词： 超纯水，运营管理，预处理阶段，反渗透阶段，EDI处理阶段 Summary Guangzhou XING efficient circuit technology limited to printed circuit board prototype, express and small batch of design and manufacturing service providers, mainly the production of high density interconnect laminate top courier and HDI rigid-Flex boards. To supply water in the production process, is invited by the company to its ultra pure water through the day-to-day operation and management of the project. Operation and management of this thesis focuses on the adoption stage of pretreatment, reverse osmosis and EDI processing phases of three major process ensures that ultrapure water production systems up and running, so that water quality meets the requirements of production water. Water is the use of municipal water supply pipes, or use a water station with water as the raw water supply water conductivity is less than 300 μg/s/cm [(25 ± 1) ° c]. According to the information provided by the owners, total water demand for 51m3/h. Among them, the first phase of demand for 42m3/h. EDI system water quality requirements to meet the standards of electronic grade water GB/T11446.1--1997 EW-ⅲ (12.0 per cent resistance ~15.0M ω. cm (25 ± 1 ° c)), while the workshop water points water resistivity 5~10M ω cm[(25 ± 1) ° c]. This thesis focuses on operational management during the stage of pretreatment, reverse osmosis EDI phases of work and functions, problems analysis and solving measures.
