摘要
Abstract
At present,the low-temperature multi-effect(LT-MED)seawater desalination water treatment agents in China are basically monopolized by foreign companies,and the price is expensive.Domestic scale and corrosion inhibitors for seawater desalination are also breaking through the bottleneck,and their quality and performance are becoming more and more mature,but they are lack of unified and systematic method verification,and lack of examination and acceptance platform for large-scale seawater desalination projects.As a result,the price of seawater desalination water treatment medicament remains high.In order to break the foreign monopoly,enhance the independent innovation ability and core competitiveness of seawater desalination agents in our country,and reduce the use cost of seawater desalination agents,a study on the application of SD210 scale inhibitor in industrial test plant was carried out by using 25 000 t/d LT-MED seawater desalination plant.The test results showed that during the 2-month test period,under the condition that the mass volume concentration of SD210 was 4～8 mg/L,the device operates safely and smoothly.No obvious scaling and corrosion.And the water quality of seawater desalination plant was better than that of Standards for Drinking Water Quality(GB 5749-2006).In summary,SD210 has good scale inhibition performance and can meet the requirements of LT-MED seawater desalination plant.关键词
