小氮肥厂稀氨水治理试验运行小结

Brief Sum-Up of Operatin of Experiment on Treatment of Dilute Aqua Ammonia in Small Nitrogenous Fertilizer Plant

通过采用高效泡罩板塔、浮阀塔 ,严格控制软水用量 ,使碳化、精炼、合成 3个工段所产生的稀氨水总量小于生产碳酸氢铵所需的稀氨水量 ,达到稀氨水的零排放 ,不仅保护了环境 ,而且取得了一定的经济效益。

By the adoption of a column with highly effective bubblecapplates and float valves and the strict control of demineralized water consumption, the total amount of dilute aqua ammonia from the three sections of carbonation, final purification and synthesis is less than the quantity of dilute aqua ammonia required for the production of ammonium bicarbonate,with zero discharge of the dilute aqua ammonia, thus not only protecting the environment but also realizing a certain economic benefit.
