Folic acid production wastewater recycling method
The invention relates to the field of medicines, in particular to a folic acid production wastewater recycling method. The invention also relates to a co-production technology of folic acid, gypsum, a desulfurization aqueous solution and a denitration aqueous solution. Particularly, the invention relates to the desulfurization aqueous solution which is obtained by compounding folic acid production wastewater with a desulfurization compound agent comprising sodium carbonate, sodium bicarbonate, sodium hydroxide, potassium carbonate, potassium bicarbonate, potassium hydroxide or a combination thereof. The invention also relates to the denitration aqueous solution which is obtained by compounding the folic acid production wastewater with a denitration compound agent comprising urea, ammonia water or a combination thereof.
本申请涉及药物领域，尤其一种叶酸生产废水再利用方法。本申请还涉及一种叶酸、石膏、脱硫水剂、脱硝水剂联产技术。特别地，本申请涉及将叶酸生产废水与包括碳酸钠、碳酸氢钠、氢氧化钠、碳酸钾、碳酸氢钾、氢氧化钾、或其组合的脱硫复配剂进行复配，以得到脱硫水剂。本申请还涉及将叶酸生产废水与包括尿素、氨水、或其组合的脱硝复配剂进行复配，以得到脱硝水剂。
