摘要
研究了活性污泥对废水中有机物的吸附效果,并以废水中COD的浓度为考察指标,对活性污泥吸附水中有机物影响的因素进行了探讨.结果表明:活性污泥对废水中的有机物的吸附效果较好,以生物吸附为主;同时,对pH为8、温度为30℃的模拟废水,以4000 mg/L的污泥的浓度对废水中的有机物吸附14 h,废水中的COD的去除率可达91.6%.
The adsorption effect of activated sludge on organic matter in wastewater was studied. Taking the concentration of COD in wastewater as an indicator, the factors affecting the adsorption of organic matter in activated sludge were investigated. The results showed that activated sludge had good adsorption effect for organic matter in the wastewater. The adsorption type was mainly biosorption. At the same time, for the simulated wastewater with the pH of 8 and the temperature of 30 °C, after the organic matter in the wastewater was adsorbed by 4 000 mg/L sludge for 14 h, the removal rate of COD in the process reached 91.6%.
