工业纯水在工业生产中应用非常广泛，其处理工艺流程在不同的出水要求中有所不同，该设计是兰州某石化企业动力厂纯水车间初步设计，该设计要求日产水量为0.5万 ，根据其进水水质为：色度≤10、浑浊度≤3、 pH值=7.65、总硬度=247.20 mg/L、碳酸盐硬度=146.50mg/L非碳酸盐硬度=81.0mg/L、碱度=146.50mg/L、总固体=505.63mg/L、Na+(K+)=59.11mg/L、Ca2+=58.04 mg/L、Mg2+=24.50 mg/L、Cl-=83.42 mg/L、SO4-2=109.44 mg/L、HCO3-=178.73 mg/L、HSiO3-=5.8 mg/L、CO2-=6.89 mg/L、细菌总数= 35个/mL，出水要求为：含盐量≤1～5mg/L,总硬度≤0.03mmol/L,二氧化硅≤0.2mg/L,pH值=7～8，电导率≤0.2us/cm,采用以离子交换的工艺进行处理，具过程为：压力过滤器→强酸阳离子交换器→除二氧化碳器→弱碱阴离子交换器→强碱阴离子交换器→混床。由于原水中强酸阴离子的含量为4.63mmol/L，需在强碱阴离子交换器之前加弱碱阴离子交换器，来降低强酸阴离子的含量。再生系统采用小反洗→反洗→顶压→再生→置换→小正洗→正洗的逆流再生系统。最后通过二级泵站将处理后的纯水送到用水区，以达到该设计的目的。
Summary
Industrial pure industrial production in a very broad application, the processing sites in different water requirements are different, the design is Lanzhou a petrochemical plant in moving enterprise workshop for the preliminary design, the design requirements Nissan water to 0.5 million, according to its get flooded water : chroma =10, and turbidity =3, pH value =7.65, =247.20 mg/L total hardness, carbonate hardness =146.50mg/L =81.0mg/L non-carbonate hardness, alkalinity =146.50mg/L, total solid =505.63mg/L, Na+ (K+) =59.11mg/L, Ca2+=58.04 mg/L, Mg2+=24.50 mg/L, Cl-=83.42 mg/L, SO4-2=109.44 mg/L, HCO3-=178.73 mg/L, HSiO3-=5.8 mg/L, CO2-=6.89 mg/L, TBC = 35 /mL, water demands are : salinity =1~5mg/L total hardness =0.03mmol/L, silicon dioxide =0.2mg/L,pH value =7~8, 6-8 =0.2us/cm, using ion exchange process for processing, and a process for : pressure filters "strong acid cation switches," in addition to carbon dioxide by "weak anion switches" base anion switches "mixed bed. Since the original water content of strong acid anions for 4.63mmol/L required in the base anion switches before vehicles plus weak anion exchange, to reduce the concentration of strong acid anions. Renewable system using small anti-wash "anti-laundering" maximum pressure "renewable" replacement "small is washing" is the current renewable washing system. Finally secondary pumping stations will be processed through the pure water to the district in order to achieve the design objectives.
