往反应釜（编号：ETF049）中加入1600~1700kg去离子水，打开反应釜的放空装置，加热到80±5oC，搅拌1小时后冷却至室温，将洗涤水排入下水道，再加入50~60kg去离子水淋洗反应釜，淋洗液排入下水道。

Add 1600 ~ 1700kg deionized water to the reactor (No.: etf049), open the vent device of the reactor, heat it to 80 ± 5oC, stir for 1 hour, cool it to room temperature, discharge the washing water into the sewer, then add 50 ~ 60kg deionized water to rinse the reactor, and the leaching solution is discharged into the sewer.

Add 1,600 ~ 1,700 kg of deionized water to the reaction kettle (No.:ETF049), open the venting device of the reaction kettle, heat it to 80±5oC, stir it for 1 hour, then cool it to room temperature, drain the washing water into the sewer, then add 50~60kg of deionized water to rinse the reaction kettle, and drain the eluent into the sewer.
