The wastewater was treated with multistage oxidation column and activated carbon adsorption column.
采取二氧化氯多级串联氧化法，再通过活性炭吸附柱处理含偏二甲肼的污水。
A new decoloring and iron-removing technology of gourmet powder was proposed and the mixing bed adsorption of multistage fluid bed (TPCIX colomn) was studied with the mixing feeding of neutralization liquid and crystallization mother liquid.
本文提出并研究了中和液与结晶母液混合进料，TPCIX柱多级流化混合床吸附的味精脱色除铁新工艺。
