SBR法处理豆制品废水工艺研究
|
摘要
采用SBR法处理模拟豆制品废水,考察低溶解氧条件下反应时间对SBR反应系统效果的影响.实验结果表明,进水COD为350~450 mg/L时,对废水中的COD、NH_4~+—N、NO_2~-—N、NO_3~-—N有较好的去除能力.当曝气3 h左右后NO_2~-—N积累达到最大值,此时停止曝气可以有效的节约曝气量和曝气时间,从而达到节约电能.减少运行成本.
The bean products wastewater treatment process has been studied by SBR. The influence of reaction time under low dissolved oxygen on SBR system was studied. The experimental results indicated that under the condition of influent COD was 330 ~ 460 mg/L,the reactor has a good degeneration ability on COD,NH_4~+—N,NO_2~-—N,NO_3~-—N. And NO_2~-—N accumulation reached a maximum after aeration 3 h. The aeration and time could be saved effectively when the aeration was stopped,and the power and costs were saved.
