02. Future opportunities

Development prospect

Energy conservation and emission reduction needs China's vast territory, a large population, the per capita occupancy of fresh water resources is less, and the reuse rate is relatively low, especially in recent years due to the rapid development of the national economy, people in the production and living activities of the water consumption is larger, the pollution problem has continued to intensify. In the process of industrial cooling water treatment, the application of water treatment agents can play a very high quality application effect. In addition, the application of water treatment agents in urban sewage treatment can also play a great auxiliary role, which is of great significance for the improvement of water resource utilization efficiency, so as to alleviate the shortage of water resources. The improvement of environmental standards In order to manage and improve the water environment quality in China's river basin, the state has introduced various policies and gradually raised the standards of sewage discharge. This also points out a very clear direction in the research and development of the new water treatment agent, which brings a good opportunity for the development of the industry. In terms of the current overall situation of China's industrial development, the most widely used scale inhibitors are mainly phosphorus products, and the country needs to consume about 100,000 tons of scale inhibitors every year. Most of these phosphorus-containing compounds end up in natural water bodies, causing eutrophication in rivers and lakes, posing a serious threat to the ecological environment. Therefore, at present, the research and promotion of non-toxic, non-phosphating and biodegradable water treatment agents is very important. Technical system support At present, China's water environment management is gradually changing from the previous total control to the target management of specific basins, the state is vigorously promoting the construction of water pollution treatment technology system and integrated management system, the development of water treatment agents has formed a very high quality technical support, showing a broader development platform.

03. Development opportunities

Innovation is the driving force for the sustainable development of water treatment agents, green is the future direction of development of water treatment agents, the development of low phosphorus, non-nitrogen, biodegradable, non-toxic and harmless, low-cost green water treatment agents suitable for China's environmental protection requirements, will become the future direction of development of water treatment agents in China. In recent years, with the formation of the depletion flocculation mechanism of organic polymer flocculants such as adsorption bridging, adsorption electric neutralization, and polymer-particulate surface complex formation, And the research on the mechanism of polyelectrolyte complex flocculation and adsorption micelle flocculation of refractory organic compounds to strengthen the flocculation mechanism provides a theoretical basis for the development and application of organic polymer flocculants and multiple composite flocculants, a number of new efficient and environmentally friendly organic polymer flocculants and multiple composite flocculants have been developed, achieving a new breakthrough in water treatment agents. Green water treatment agents The development of green water treatment agents has experienced the process from natural polymer green water treatment agents to artificial synthetic polymer green water treatment agents. The development of new green water treatment agents with high scale inhibition, good biodegradability, non-toxic, phosphorus free or low phosphorus is the development direction of water treatment agents in the 21st century. 

However, at present, only scale inhibitors and corrosion inhibitors have made certain progress in greening, while flocculants, as the most important and the most used reagents, still have secondary pollution problems in the inorganic and organic flocculants currently used, and are easy to cause significant harm to human health, so the research and development of their greening process should be increased. In the development process, natural products such as agricultural and forest products are used as raw materials, supplemented by W/W emulsion polymerization technology, so that the production and use of green, and no secondary pollution. Multi-component composite water treatment agent multi-component composite water treatment agent is a kind of water treatment agent with one dose of multi-effect, such as polysilicic acid and aluminum salt composite flocculant, is a new type of inorganic polymer coagulant, is developed on the basis of activated silicic acid (that is, polysilicic acid) and aluminum salt coagulant composite product, and has electric neutralization and adsorption bridging effect. This kind of coagulant has the advantages of good coagulation effect, low price and low amount of residual aluminum in the treated water. Another example is the polyhalogenated alcohol thiazaline quaternary ammonium salt flocculant, which has the characteristics of strong flocculation ability, especially suitable for the separation of ore and water in beneficiation operations, and also has certain bactericidal and slow-release effects. The characteristics of multiple compound water treatment agents with multiple effects in one dose attract more and more researchers to engage in the research and application development of its preparation technology.
