4.3us/cm is passed through 2m in the corresponding inlet tank in light room3Certain power plant desulfurization wastewater, desulfurization wastewater conductivity are 46706us/cm,
Calcium ion content 4470mg/L, magnesium ion content 3150mg/L, sodium ions content 2275mg/L, chloride ion 18200mg/L, sulfuric acid
The saturation index of root 3000mg/L, sulfate radical and calcium ion is up to 158%, is easily easy to produce fouling.Dense room flow of inlet water is
5m3/ h, pressure 2kpa.Light room flow of inlet water is 8m3/ h, water inlet pressure are 3kpa.Electrodialysis uses constant voltage operation side
Formula, operation voltage are 150V, and current range is 40~150A.After operation 70 minutes, concentrated water and fresh water inlet tank are produced respectively
Water 0.5m3And 1.95m3.Assay, Analysis Results of Water Quality are sampled to the production water in inlet tank are as follows: concentrated water case most produces water power
Conductance is 133947us/cm, calcium ion content 15700mg/L, magnesium ion content 11320mg/L, sodium ions content 7205mg/L,
Chloride ion 71819mg/L, sulfate radical 11mg/L.Fresh-water tank most produce water conductivity be 5443us/cm, calcium ion content 558mg/L,
Magnesium ion content 328mg/L, sodium ions content 485mg/L, chloride ion 323mg/L, sulfate radical 3094mg/L.By the electrodialysis
The 1.95m that desulfurization wastewater is desalinated, and obtained after device processing3Fresh water, this fresh water can be back to desulfurizing tower use.It obtains simultaneously
Obtain 0.5m3Concentrated water, for concentrated water mainly with the combining form of monovalent anion and a variety of valence states cation, sulfate radical is only 11mg/L,
The saturation index of sulfate radical and calcium ion is only 1.18%, avoids calcium sulfate and generates fouling in dense room in electric dialyzator.
The product form and style of above-described embodiment and schema and non-limiting the utility model, any technical field
The appropriate changes or modifications that those of ordinary skill does it all should be regarded as the patent category for not departing from the utility model.
