Description
Technical Field

Background
In the chlor-alkali industry, the waste alkaline water left after the production of the cathode and anode electrolytic bed contains a large amount of calcium, magnesium and other divalent metal ions, auxiliary materials are required to be added to carry out precipitation treatment on the divalent ions of calcium and magnesium in sequence before the waste alkaline water is discharged, and the residual waste water can be discharged after the next step of waste water chelating regeneration and recovery process is finished.
The treatment technology of waste acid alkaline water is gradually improved at present, in the treatment step, the bipolar wastewater in a cathode-anode electrolytic bed can be led into a sedimentation tank, the pH value is adjusted, sea salt is added, steam is introduced at the same time to convert the neutralized wastewater into saturated brine, soda ash is added to enable calcium ions in the waste acid alkaline water to generate sediment, the residual waste acid alkaline water overflows to the next sedimentation tank, and caustic soda is added to obtain magnesium ion sediment.
However, the introduced steam can continuously roll upwards in the solution, so that the added sea salt and a large amount of generated calcium precipitates are mixed and mixed together, the waste acid alkaline water newly introduced into the sedimentation tank cannot be efficiently contacted with the sea salt, and the calcium precipitates generated in the sedimentation tank can inhibit the growth rate of the new precipitates if the calcium precipitates are not timely fished out, so that the generation rate of the calcium precipitates is lower than the expected value, and in addition, the steam which rolls upwards easily stirs the precipitated calcium precipitates upwards, so that the calcium precipitates easily flow into the next sedimentation tank along with the alkaline water at the top layer through an overflow gate, and the treatment of magnesium ion precipitation is influenced.
