摘要：

针对酱油废水组分复杂、色度较高的特点, 在(35±1)℃下, 采用厌氧折流板反应器(ABR)对酱油废水进行了处理试验, 研究了该反应器处理酱油废水的脱色效果和运行特性。结果表明;当色度由150倍逐步增至750倍, COD由500 mg/L逐步增至6500 mg/L时, 色度去除率均在30%以上, 最高可达50.2%, 各格室色度沿程呈递减趋势;COD去除率维持在91.0%～95.1%。在COD去除率一定的情况下, 当HRT为20 h时, 色度去除率最高, 为47.5%。

Abstract:

Soy sauce wastewater is characterized by complicated components and high chroma.Its start-up experiments has been carried out by using anaerobic baffled reactor(ABR) for treating soy sauce wastewater at(35±1) ℃.The decoloration effect and operation characteristic of anaerobic baffled reactor(ABR) are studied.The results show that when the chroma increases from 150 times to 750 times gradually, and COD increases from 500 mg/L to 6500 mg/L, gradually, the chroma removing rate is above 30%, even the highest can reach 50.2%.The chroma exhibits a decreasing trend along every lattice.The COD removing rates could be maintained between 91.0%-95.1%.For the definite COD removing rate, when HRT is 20 h, color removing rate will be the highest, about 47.5%.

Key words: soy sauce wastewater, chroma, anaerobic baffled reactor, decoloration
