Problems solved by technology

These water treatment technologies have been able to control the content of organic matter in water to a higher level, but they have many shortcomings: low efficiency, high cost, difficult regeneration, secondary pollution, etc., even if they have good application prospects Nano-TiO 2 Photocatalytic degradation technology, although the cleanliness is high and pollution-free, but this technology requires the treatment water to stay in the catalytic oxidation reaction generator for a long time, more than 1h can have a good effect. At the same time, nano-TiO 2 Fine particles, inconvenient to recycle
