【摘要】：饮用水安全是人们生命健康和社会发展的重要保证。但村镇饮用水安全依旧处于较差的水平。目前仍有3亿村镇人口(中西部占80%)饮用水未达到国家要求的安全标准。这其中,由于水质不达标而造成的不安全占比高达70%。究其难以改善的原因,一方面是由于水源水质加速的恶化和生产管理水平的落后;另外一方面则是因为科研新成果在村镇市场的推广困难重重。论文为基于异向流螺旋斜板沉淀反应器的一体化净水设备的专利转化及推广研究。专利转化环节分为:资料搜集、市场调研、设备改进和定型、最后为玉树小区展示工程的建设与试运行。这其中论文最核心的3部分为市场调研,设备改进与定型和玉树小区展示工程。论文选取了四川周边交通较为便利的21处村镇及云南、青海4处有设备需求的地点作为饮用水调研地。通过调研,客观的了解到了一体化净水设备和西南村镇供水的现状,同时也判断基于异向流螺旋斜板沉淀技术的新型一体化净水设备有着广泛的应用前景且具有投产的必要性。设备改进和定型。根据调研结果和初期设备试运行情况,在设备投产前对其进行了结构、工艺等方面进行改进。并形成完整的供水方案,增加了定型后设备的运行稳定性和管理的便捷性。设备结构改进包括支腿、环形槽、反应桶顶部,滤床滤头、液位传感器、顶盖、集泥锥形桶角度、落水斗等改进。工艺改进为絮凝板开孔优化和引入短程深度处理工艺。在该部分,论文提出来一种基于一体化净水设备的炭砂滤床构建方法,并对构建的滤床进行了实验分析。同时也提出了一整套包含自动化控制、在线监测系统、加氯加药系统等系统的供水方案。最后整理形成了《产品设计计算说明书》、《产品质量控制手册》、《设备安装规范》、《设备运行规范》、《设备生产工艺规范》的技术文件。论文还开展了四川南充市玉树小区示范工程工作。该示范工程兼具实际供水、后期实验和设备推广展示需求。根据该需求,展区设计分为了功能区和试验区。示范工程建设完成后,通过试运行对定型后的CPLX10-240-A型设备进行了、浊度、CODMn、氨氮、UV254去除性能及抗浊度冲击负荷、抗流量冲击负荷、反冲洗恢复性评价。抗高浊度原水冲击试验中,当原水平均浊度1058NTU加药量25mg/L时,12小时内平均出水浊度0.683NTU,浊度去除率高于99%。示范工程稳定运行后,当原水浊度、CODMn、氨氮为68.521NTU、4.08mg/L和0.34mg/L时设备出水分别为0.241NTU、1.82mg/L、0.28mg/L。
[Abstract]:Drinking water safety is an important guarantee for people's health and social development. But the safety of drinking water in villages and towns is still at a poor level. There are still 300 million people in villages and towns (80% in the Midwest) drinking water that does not meet the national safety standards. Among them, the proportion of unsafe water quality is as high as 70%. The reason why it is difficult to improve is on the one hand the accelerated deterioration of water quality and the backward level of production management; on the other hand, it is difficult to popularize the new achievements of scientific research in the village and town markets. This paper is about patent conversion and extension of integrated water purification equipment based on helical oblique plate sedimentation reactor. Patent conversion is divided into: data collection, market research, equipment improvement and finalization, and finally the construction and trial operation of Yushu community display project. The three core parts of the thesis are market research, equipment improvement and design, and Yushu community display project. In this paper, 21 villages and towns with convenient transportation around Sichuan and Yunnan and 4 locations with equipment demand in Qinghai are selected as drinking water research sites. Through investigation and investigation, the authors objectively understand the present situation of integrated water purification equipment and the water supply in southwest villages and towns. At the same time, it is judged that the new integrated water purification equipment based on the technology of countercurrent helical inclined plate sedimentation has a wide application prospect and is necessary to put into production. Equipment improvement and finalization. According to the results of investigation and preliminary operation of the equipment, the structure and process of the equipment were improved before it was put into production. A complete water supply scheme is formed to increase the operation stability and management convenience of the equipment. The improvement of equipment structure includes support leg, ring groove, top of reaction barrel, filter head of filter bed, liquid level sensor, top cover, angle of mud collecting cone bucket, falling bucket and so on. The process was improved to optimize the opening of flocculation plate and to introduce short-range advanced treatment process. In this part, a construction method of carbon sand filter bed based on integrated water purification equipment is proposed, and the experimental analysis of the constructed filter bed is carried out. At the same time, a whole set of water supply schemes including automatic control, on-line monitoring system and chlorinated dosing system are put forward. Finally, the technical documents of product design calculation manual, product quality control manual, equipment installation specification, equipment operation specification and equipment production process specification are formed. The paper also carried out the demonstration project of Yushu District in Nanchong City, Sichuan Province. The demonstration project has both the actual water supply, the later stage experiment and the equipment promotion demonstration demand. According to this demand, the design of exhibition area is divided into function area and test area. After the construction of the demonstration project was completed, the final CPLX10-240-A equipment was tested. The removal performance of turbidity, COD mn, ammonia nitrogen, UV254 and anti-turbidity impact load, flow impact load and recoverability were evaluated. In the impact test of high turbidity raw water, when the average turbidity of raw water was added with 25mg/L, the average turbidity of water was 0.683 NTU within 12 hours, and the turbidity removal rate was higher than that of 99g. After stable operation of the demonstration project, when the turbidity of raw water is COD mn, ammonia nitrogen is 68.521 NTU 4.08 mg / L and 0.34mg/L is 0.241 NTU 1.82 mg / L, 0.28 mg / L respectively.
