Large industrial wastewater treatment equipment operation Shanghai exceeded the conductivity of the solution author of the article: Many small and large due to the general industrial wastewater is not treated before it is discharged, so that sewage has a serious impact on the living environment, the country now requires a certain wastewater discharge At the same time, we are now beginning to pay attention to environmental protection, water pollution and water shortages have intensified, and now we are also reducing pollution in various aspects. Sewage treatment equipment can be an effective way to solve water pollution and increase the rate of sewage reuse. Therefore, various industries have used large-scale industrial sewage treatment equipment. Electrical conductivity is an indicator to measure the effluent quality of large-scale industrial sewage treatment equipment. If the electrical conductivity exceeds the standard, the quality of the effluent water of large-scale industrial sewage treatment equipment cannot meet the requirements. Therefore, when the electrical conductivity exceeds the standard, we should find out the reason and solve it. The editor will take you to take a look at how to deal with the excessive conductivity of large-scale industrial sewage treatment equipment. 1. Water quality problem: Check whether the water quality of the raw water has changed significantly. Method: If the conductivity of the produced water increases due to an abnormal increase in the conductivity of the inlet water, the conductivity of the produced water can be adjusted, and the conductivity of the produced water will return to normal after the conductivity of the inlet water returns. 2. Conductivity meter: check whether the conductivity meter works normally. Method: If the meter displays incorrect values, replace the conductivity meter with a new one. 3. Membrane module problem: Check whether the reverse osmosis membrane module is aging or oxidized medium. Method: If it is because of this reason that the salt rejection rate drops, replace the reverse osmosis membrane module. 4. Reverse osmosis membrane fouling: reverse osmosis membrane fouling due to pollution. Method: To clean the reverse osmosis membrane, it is recommended to carry out regular chemical cleaning according to the operating instructions. 5. Operation problems: Whether there is an instant shutdown or improper operation. Method: This situation is likely to cause reverse osmosis membrane back pressure, reverse osmosis membrane rupture, and cause the water conductivity to rise sharply after restarting. The above is all about the treatment methods for the conductivity of large-scale industrial sewage treatment equipment to exceed the standard. I hope you can get help after reading.
