还原法处理电镀废水后铬反弹成因分析与对策
The problem and countermeature about electroplating wastewater with reduction method
【摘要】 从化学热力学和电化学理论出发 ,结合目前普遍采用的还原 -固体分离法处理含铬废水工艺 ,对固液分离后的上清液和沉降污泥 Cr6 +含量以及 Cr3+~ Cr6 +之间的形态转化相关性进行研究和分析 ,进而提醒人们要特别注意控制含铬污水中铬反弹及全过程处理的完整性。
【Abstract】 Proceed from the theory of chemistry thermodynamics and electrochemistry, combing with the technology of reduction-solid and liquid separated method to deal with chromium content of wastewater, that universally used at present, the content of Cr + {6+ } in the clear above liquid and the sediment along with the form changing that occurred in Cr + {3+ }~Cr + {6+ } were analysed. Special attention to later period of dealing with the chromium content in the wastewater and the completeness of the whole process should be given. ;
