Rectification measures: Based on the main parameters of the design scheme for the fluctuation bed ion exchanger of the reverse osmosis equipment, as shown in Table 4.21, the HCI concentration value of the regeneration solution is between 1.5% and 3%. A regeneration concentration value of 1.8% to 2.0% can be used, and the regeneration time should be ensured to be 30 minutes. After the acid inlet is completed, it should be switched to a new position. Using pure sulfuric acid with an HCI amount of 30-40kg/m3, it should be calculated as ⒛% industrial production H α The amount is 30 ÷ 30%=100kg/durable, and after 10 rain cycles, the acid concentration value should be checked to be no less than 0,4%~0.5%. The cation exchange resin foundation should be completely regenerated, so that acid consumption can be reduced.

Fluctuating beds are not suitable for low flow rate operation, as low flow rate operation can increase acid consumption and should be operated at high flow rates. High flow rate operation, high cost-effectiveness of water production, large cycle time water production flow rate, low acid consumption, operating flow rate from 30 η/ When h is increased to 40m/h, the water production rate during the cycle time can be increased by 10% to 15%. Through experiments, it has been found that when the operating flow rate reaches 90m/h, the quality of the produced water is still very good. However, when the operating flow rate is high, the resin is suitable for crushing. Therefore, the operating flow rate should be controlled at a speed of 40m/h for better flow rate and 45-50 meters/h for higher flow rate, otherwise the resin pile density will increase. The operating flow rate is controlled below 35m/h, and the resin pile density is very low. If it is less than 30m/h, resin crushing will not occur.
