加压生物氧化法处理助剂厂废水的研究

Study on Application of Pressurized Biological Oxidation Process for Treatment of Wastewater from Auxiliary Agent Plant

用新研制开发的加压生物氧化设备对助剂厂可生化废水进行了处理试验 ,在曝气罐中废水压力为 2 0 0 k Pa、进水 COD为 2 80 0～ 30 0 0 m g/ L、曝气 11～ 12 h的条件下 ,处理后出水的COD≤ 2 0 0 mg/ L 。

The recently developed pressurized biological oxidation equipment has been used for treating biodegradable wastewater from auxiliary agent plant.Under the conditions of 200 kPa of wastewater pressure in the reaction tank,influent COD of 2800~3000 mg/L and 11~12 h of aeration time,the effluent COD is equal to or less than 200 mg/L,which can meet the discharge limit specified for the industrial sector.
