<p>A malachite green dye waste water treatment method, comprising the following steps: (1) mixed adsorbent preparation: mixing steel slag and coke in the mass ratio of 1:0.8-1.5; (2) oscillation: adding the mixed adsorbent with 0.8-2% mass percent of waste water to the malachite green dye waste water, and oscillating for 0.5-30h; (3) solid-liquid separation: separating the steel slag from the waste water to obtain the treated water. The method is characterized by a simple method, low production cost, high efficiency and short treatment time; furthermore, the used steel slag can be recycled after microwave treatment, thus avoiding secondary pollution.</p> |
