二级厌氧—SBR工艺处理酱油生产废水

Two Stair Anaerobic-SBR Process Treaatment of Soy Wastewater

酱油工业废水组分复杂 ,常含有多种有机物质 ,色度深 ,难于降解 ,且水质水量波动较大。文章介绍了采用二级厌氧—SBR工艺 ,先在厌氧反应池内加入弹性立体填料 ,后接SBR反映器处理酱油生产废水 ,以及废水处理的设计特点、工程特点和处理效果。运行结果表明 ,吨水投资费用为 0 2 9万元 ,吨水运行成本 0 4元 ,且处理效果较稳定 。

Wastewater of soying industry has complicated constituents,and usually contains many kinds of organic things. It has deep tinct, and it is difficult to decompose, and a large fluctuation exists in water character and flow. The paper essentially introduces how to apply the treatment technology of two stair anaerobic_SBR process to treat the soy wastewater. At first, the anaerobic tank must be filled with the spring solid packing, also as a SBR reactor pond are followed. By analyzing the feature of the design,the characteristics of the engineer and the treatment efficiency, the final results show that the average investment of one ton wastewater is 2.9 thousand yuan,and the average treatment fee of one ton is about 0.4 yuan. The most importance is the steady treatment result and the final effluent quality can meet the national standard.
