The Strengthening Effect Of Microwave Internal The Electrocoagulation Processing Sulfur Wastewater

There is so much organic vulcanized substance in industry waste water which has flotation agent in it, because the toxicity of this kind of waste wanteris big and it is difficult to degrade it, Few reports about achieveable manage technology have been seen now. In view of the peculiarity of this kind of waste water, this article proposed the method of strengthening the electrolysis and flocculation. This article also discussed the effect and the influence factor. Through the experimental study, we have chosen a reasonable amount used and the response condition.We Selects some vulcanized waste water as the study object; carries a series of experiments on it; discussed the processing effect of this mehted. The quality of wastewater is pH 9, chromaticity 150, turbidity 90, CODcr concentration 28130mg/L.The testing steps is: Under the optimal conditions of pH 2, the mass of cast iron and active carbon are 140g and 100g respectively, microwave irradiation power was 300W, the radiation time was 4 min and the aeration intensity was 3. 5L/min. The removal rates of chromaticity was 93%, turbidity was 92% and CODcr was 95. 96% which was improved by 7%, 28. 58% and 17.58%compared to single micro-electrolysis process.The result showed the best experiment conditions: the quality of Fe(140g), the quality of C(100g), pH=2, the power of microwave(40%), the time under themicrowave(4min) and the ventilation quantity is 3.5L/min.Based on the experiments, we studied on the treatment of microwave & micro-electrolysis which showed that the treatment was feasible to apply in industry with the following advantages: adaptability, stable treatment efficiency and low operating cost.
