摘要
根据磷矿浮选工艺要求和废水的性质,利用CaO和Na2CO3两碱处理选矿废水,废水循环回用,达到回水的100%利用,即"零排放"。该工艺既防止了浮选废水对环境的潜在污染,降低了浮选药剂消耗,又充分利用了水资源,工艺简单,易于工业化。
Based on the requirement of phosphorite processing technology and the characters of wastewater, the technology of treatment phosphorite processing wastewater with CaO and Na2CO3 and recycling utilization of wastewater was studied. The utilization ratio of wastewater is 100%. The experiment results indicate that the technology can prevent the potential environmental pollution causing by wastewater, and reduce the amount of flotation agent. The water resource can be utilized fully. The technology is briefness and industrialization.
