Description
技术领域 technical field
本实用新型涉及一种反渗透水处理阻垢剂质量评价试验装置。 The utility model relates to a quality evaluation test device for reverse osmosis water treatment scale inhibitor. the
背景技术 Background technique
反渗透技术，是当今最先进和最节能有效的膜分离技术。其原理是在高于溶液渗透压的作用下，依据其他物质不能透过半透膜而将这些物质和水分离开来。随着水污染的日益严重，反渗透纯水技术已成为解决水资源短缺的最有发展前途的技术之一。 Reverse osmosis technology is the most advanced and most energy-saving and effective membrane separation technology today. The principle is to separate these substances from water based on the fact that other substances cannot pass through the semi-permeable membrane under the action of higher than the osmotic pressure of the solution. With the increasingly serious water pollution, reverse osmosis pure water technology has become one of the most promising technologies to solve the shortage of water resources. the
在反渗透膜上形成污垢与沉积物垢会使水处理系统性能恶化，并需要提前更换反渗透膜。积聚在反渗透膜上的污垢与沉淀物将造成渗透性能恶化，透过量减少，频繁停机，水耗量增多以及能耗增大。为了减缓或抑制膜的污堵，保证反渗透系统长期有效地运行，清除反渗透膜上无机垢、有机污垢和生物污垢，必须添加反渗透水处理药剂。因此，对反渗透膜水处理药剂评价方法至关重要。 Formation of scale and deposits on RO membranes can degrade water treatment system performance and require premature RO membrane replacement. Fouling and sediment accumulated on the reverse osmosis membrane will lead to poor permeability, reduced permeation, frequent shutdowns, increased water consumption and increased energy consumption. In order to slow down or inhibit the fouling of the membrane, ensure the long-term effective operation of the reverse osmosis system, and remove the inorganic, organic and biological fouling on the reverse osmosis membrane, it is necessary to add reverse osmosis water treatment chemicals. Therefore, the evaluation method of reverse osmosis membrane water treatment agent is very important. the
目前广泛使用的反渗透膜阻垢剂的评价方法包括静态评价法和动态评价法。静态法是一种实验室评价方法，特点是设备简单、试验时间短，能够一定程度反映阻垢剂性能的好坏；动态法是一种介于实验室和现场的评价方法，通过模拟现场水质，利用小型反渗透装置对反渗透膜阻垢剂进行评价。测定进水、产水和浓水中结晶离子浓度、设备脱盐率、系统压降、产水量等指标，考察膜的结垢情况。 The currently widely used evaluation methods for reverse osmosis membrane scale inhibitors include static evaluation method and dynamic evaluation method. The static method is a laboratory evaluation method, which is characterized by simple equipment and short test time, and can reflect the performance of the antiscalant to a certain extent; the dynamic method is an evaluation method between the laboratory and the field. , using a small reverse osmosis device to evaluate antiscalants for reverse osmosis membranes. Measure the concentration of crystallization ions in the influent, product water and concentrated water, equipment desalination rate, system pressure drop, water production and other indicators, and investigate the fouling of the membrane. the
目前，我国对反渗透水处理阻垢剂评价方法的建立工作相对较少，基本停留在应用循环水药剂评价方法上，而市售的循环水阻垢剂性能评定装置(静态、动态)主要是上世纪八十年代初按化工行业标准研制的，在可靠性和功能上都无法适应用户的需要，这样极不利于反渗透膜阻垢剂的正确选用和新型高效反渗透膜阻垢剂的研制。 At present, the establishment of antiscalant evaluation methods for reverse osmosis water treatment in my country is relatively small, and basically stays in the application of circulating water chemical evaluation methods, while the commercially available circulating water antiscalant performance evaluation devices (static, dynamic) are mainly It was developed according to the standards of the chemical industry in the early 1980s, but it cannot meet the needs of users in terms of reliability and function, which is extremely unfavorable for the correct selection of antiscalants for reverse osmosis membranes and the development of new high-efficiency antiscalants for reverse osmosis membranes. . the
每年国内外都有新型反渗透专用阻垢剂问世，阻垢剂产品说明书提供的加药剂量、适用条件等缺乏针对性，与用户具体水质条件存在较大偏差，常常需要在用户反渗透设备长期运行中监测和积累阻垢剂性能数据。尽管这与反渗透系统实际运行情况一致，但这些数据仅针对当地具体水源水质和特定的膜系统，且现场测试时间长、药剂消耗量相当大，具备一定的风险性。因此，需要研发一种适用于用户客观、科学、可靠评价阻垢剂性能试验装置，以指导用户最优化地选用阻垢剂。 Every year, there are new antiscalants for reverse osmosis at home and abroad. The dosing dosage and application conditions provided by the product instructions of the antiscalants are not targeted, and there are large deviations from the specific water quality conditions of users. Monitor and accumulate antiscalant performance data during operation. Although this is consistent with the actual operation of the reverse osmosis system, these data are only for the specific local water quality and specific membrane system, and the field test takes a long time and consumes a lot of chemicals, which has certain risks. Therefore, it is necessary to develop a test device suitable for users to objectively, scientifically and reliably evaluate the performance of scale inhibitors, so as to guide users to optimize the selection of scale inhibitors. the

进行动态试验某一试验方法时，对比有无添加阻垢剂、阻垢剂添加剂量的不同，产水电导率、产水量、系统压差等监测指标的变化。运行一段时间时，浓水侧离子浓度高，离子浓度积远大于溶解度常数，结垢趋势增大，产水电导率增大，即脱盐率下降；单位时间产水量下降；系统压差增大。若添加阻垢剂阻垢性能优异，能有效增大水中游离离子含量，抑制晶体的生成，那么，相同运行周期内，产水电导率、脱盐率、单位时间产水量、系统压差等指标的变化均较缓慢。反之，通过比较产水电导率、脱盐率、单位时间产水量、系统压差等指标的变化趋势，亦能直观明显地判断反渗透水处理阻垢剂性能的优劣。 When performing a dynamic test for a certain test method, compare the changes in monitoring indicators such as the presence or absence of scale inhibitors, the amount of scale inhibitor additives, the conductivity of the produced water, the amount of produced water, and the system pressure difference.

If the addition of scale inhibitors has excellent scale inhibition performance, can effectively increase the content of free ions in water, and inhibit the formation of crystals, then, within the same operating cycle, the performance of the water conductivity, desalination rate, water production per unit time, and system pressure difference will increase. Changes are relatively slow.

此外，本装置不仅仅不单一考察阻垢剂的阻垢作用，同时也考虑阻垢剂的微生物滋长作用、与絮凝剂生成胶体沉积物、水流通道狭窄诸问题引起的反渗透膜污堵、系统故障等。装置中的恒温装置7能有效地减小气候气温的影响，消除系统水循环过程产生的热量，能真实地模拟反渗透系统的运行工况。可以灵活添加在线监测仪表，如增加监测微生物滋长的监测设备——氧化还原电位仪表等，通过在线仪表长期的数据记录，建立阻垢剂种类、剂量等与反渗透系统污堵的数学模型，从而多方面考察阻垢剂的阻垢性能、与混凝剂、絮凝剂兼容性能、滋长微生物性能以及药剂长期运行性能，进而评价药剂的性能，便于用户根据水源水质和具体的膜系统选择合适的反渗透水处理药剂和添加剂量。 In addition, this device not only examines the antiscalant effect of the antiscalant, but also considers the microbial growth of the antiscalant, the formation of colloidal deposits with the flocculant, the fouling of the reverse osmosis membrane caused by the narrow water channel, and the system fault etc. The constant temperature device 7 in the device can effectively reduce the influence of climate and temperature, eliminate the heat generated during the water circulation process of the system, and can truly simulate the operating conditions of the reverse osmosis system. It is possible to flexibly add online monitoring instruments, such as adding monitoring equipment for monitoring microbial growth - redox potential instruments, etc., through long-term data records of online instruments, establish a mathematical model of antiscalant type, dosage, etc. and fouling of reverse osmosis system, so as Examine the antiscalant performance, compatibility with coagulants and flocculants, growth of microorganisms and long-term running performance of the antiscalant in many aspects, and then evaluate the performance of the antiscalant, so that users can choose the appropriate antiscalant according to the water quality of the water source and the specific membrane system. Osmotic water treatment chemicals and additives. the
