摘要:

采用铁炭微电解法去除超高盐榨菜废水中的磷,研究反应时间、初始pH、铁炭体积比和铁水体积比对溶解性磷酸盐去除率的影响.初始pH=6、铁炭体积比1∶1、铁水体积比1∶1、反应时间30 min时,进、出水磷的质量浓度分别为169.30、5.51 mg/L,去除率96.74%.扫描电镜及X射线能谱结果表明,反应后铁屑表面被沉淀物所覆盖,铁元素减少,磷和氧元素增多.

Abstract:

The iron-carbon micro-electrolysis process has been used for removing phosphorus from preserved Sichuan pickle wastewater whose salinity is ultra high. The effects of reaction time,initial pH,volume ratio of Fe/C and volume ratio of Fe/H2O on the removing rate of solubilized phosphate are investigated. The removing rate is 96.74%,when the initial pH is 6,volume ratio of Fe/C 1∶1,volume ratio of Fe/H2O 1∶1,reaction time 30 min,and the mass concentrations of phosphorus in influent and effluent water are 169.30 mg/L and 5.51 mg/L,respectively. The results of SEM and EDS analysis show that the scrap iron surface has been covered with sediment,iron content decreased, and phosphorus and oxygen content increased.

Key words: iron-carbon micro-electrolysis, preserved Sichuan pickle wastewater, dephosphorization
