直接燃烧法治理硫化物恶臭污水的研究

STUDY ON STINKING SULFIDE WASTEWATER TREATMENT WITH DIRECT BURNING

在酸性条件下，用水蒸气将恶臭物质（Ｈ２Ｓ和ＣＨ３ＳＨ）由污水中载出，送入石油气和空气火焰中燃烧。用ＮａＯＨ溶液吸收废气中的ＳＯ２和ＣＯ２。污水经上述处理后，加入适量ＮａＣｌＯ溶液，将其残存的恶臭物质完全氧化。最后过滤、中和，成为无色、无臭的透明溶液，排放。本法已在有关工厂中应用。

Under acid condition stinking sulfides, such as H 2S and CH 3SH, were carried from the wastewater to petrolum gas air flame by steam. CO 2 and SO 2 generated during the sulfide burning were absorbed by NaOH solution. A certain amount of NaClO solution was added to the wastewater treated to climinate residue stinking substances. After filtratation and neutralizing, odorless and colourless solution was obtained and drained away. This method was applied to relative factory. A good result for treatment stinking wastewater was obtained.
