AI Technical Summary
Existing technologies are ineffective at treating high-concentration industrial reverse osmosis brine, leading to resource waste and environmental pollution, as well as high treatment costs and low efficiency.
The treatment system consists of an ozone oxidation tank, a desulfurization and defluorination tank, an electrocoagulation device, a calcium aluminum salt precipitation tank, a CO2 aeration tank, a sand filter, and an ultrafiltration tank. It treats concentrated brine through ozone oxidation, electrocoagulation, and calcium aluminum salt precipitation technologies to achieve resource utilization.
This method enables the effective treatment of high-concentration brine, yielding precipitates that can be used as high-quality cement, adsorbents, and catalysts. It reduces treatment costs and environmental pollution, and improves resource utilization efficiency.
