Coal industry strong brine removes isolated plant of silicon technology

The utility model discloses a coal industry strong brine removes isolated plant of silicon technology to adding the magnesia mixture in the coal industry strong brine, then adds lime or lime breast orpiece alkali, carries out the silica removals reaction of two stages, goes out that sodium carbonate is added again to water, the flocculating agent carries out coagulating sedimentation, gets rid ofthe silicon and the calcium of aquatic, and the supernatant filters through manganese sand, gets rid of the iron of aquatic. The utility model discloses a silica removal device simple structure, thesilica removal is efficient, goes out water total silicon content and can reduce to below the 30mgL, can avoid the silicate scale deposit risk among the follow -up evaporation crystallisation process.And simultaneously, the utility model discloses make full use of relict magnesium oxide and magnesium hydroxide granule, not only reduced the dosage of throwing of medicament, reduced the sludge treatment volume, reduced second
