example 1
[0029] Example 1: The concentrated brine produced by the RO system from the sewage source, the water quality conditions are: conductivity 100000μs / cm, chromaticity 80. The device for treating high brine with hydroelectric molecular membrane is used to treat wastewater. The membrane group adopts a tubular hydroelectric molecular membrane membrane, the temperature of the feed liquid is 40°C, and the vacuum degree is -0.1MPa. The final effluent conductivity is 53μs / cm, no color, the desalination rate reaches 99.9%, the chroma removal rate is 100%, and the average flux of membrane produced water has been maintained at 10L / m 2 .h;
example 2
[0030] Example 2: The source of sewage is the effluent of the biochemical system of a coking plant, and the water quality condition is: COD Cr The content is 680mg / L, the SS is 600mg / L, the conductivity is 8900μs / cm, and the chromaticity is 500; the device for treating high salt water with hydroelectric molecular membrane is used to treat the wastewater. The inlet water temperature is 80°C and the vacuum degree is -0.1MPa. Final effluent conductivity is 90μs / cm, COD Cr 50mg / L, no color, the total nitrogen concentration is less than 10mg / L, that is, the desalination rate is 99%, 100% removes chroma, and reaches the industry’s first-class discharge standard A. The average flux of membrane-produced water has been maintained at 100L / m 2 .h.
example 3
[0031]Example 3: The source of sewage is seawater, and the water quality conditions are: conductivity 32000μs / cm, chromaticity 30. The device for treating high brine with hydroelectric molecular membrane is used to treat wastewater. The membrane group adopts 14 pipe-type hydroelectric molecular membrane membranes. The feed water temperature is 60°C and the vacuum degree is -0.1MPa. The final conductivity of the effluent is 3.0μs / cm, no color, the desalination rate reaches 99.99%, 100% removes the color, and the average flux of the membrane produced water has been maintained at 25L / m 2 .h;
