硝基氧化剂废水处理研究

Research on the disposal technology of nitro-oxidizer waste water

用钠盐 ( Na2 CO3和 Na HCO3)作中和剂去除硝基氧化剂废水中 HNO3;用尿素、Na2 SO3去除 NO- 2 、NO- 3 ;加入适量的沉淀剂、络合剂、絮凝剂、助凝剂去除废水中的 F-和 PO3- 4 ;并对处理 p H值、各种药剂浓度及处理时间作了讨论 ,得出了最佳条件 。

The disposal technology of nitro\|oxidizer waste water was discussed, that were HNO\-3 neutralized by Na\-2CO\-3 and NaHCO\-3, NO\+-\-2 and NO\+-\-3 reduced by CO(NH\-2)\-2 and Na\-2SO\-3, F\+- and PO\+\{3-\}\-4 got rid of by the appropriate precipitant, complexing agent and flocculant, promoter, and the optimmum condition about the concentration of the neutralizer, the reducing agent, the precipitant, the complexing agent and the flocculant, the value of pH, the response time were obtained. The effluent came to national effluent standard.\;
