摘要:
污泥浓度作为城市污水处理厂设计和运行管理过程的一个重要参数,目前主要采用重量法测定,该方法在应用过程中最大的缺点是耗时耗能.本研究采用分光光度法在OD600处测定活性污泥的浓度,建立测定的方法,优化测定的预处理条件,并对测定结果进行了误差分析.结果表明,分光光度法测定活性污泥浓度的较佳范围为0.996~3.864g/L,较佳的稀释液和空白应为超纯水,预处理的最佳条件为功率110W时超声处理4min.总之,分光光度法具有节能、省时、误差小的特点,是一种简单实用的污泥浓度测定方法
Abstract:
The suspended solid concentration in mixed liquid(MLSS)of activated sludge is an important parameter for designing and operating a wastewater treatment plant and is usually determined by gravimetric analysis, which is time-consuming and energy-consuming. This paper aimed to apply a procedure based on spectrophotometric analysis for rapid quantifying MLSS concentration of activated sludge at the wavelength of OD600.The pretreatment condition was optimized and measurement error was analyzed later after a detailed recipe was proposed. The results showed that the preferable range of activated sludge concentration ranged between 0.996~3.864gMLSS/L.As for the diluent and blank in the spectrophotometric analysis, deionized water was favored. Meanwhile the optimal condition of ultrasonic pretreatment was under 110W for 4minutes.Compared with gravimetric method, spectrophotometric analysis is a time-thrift, energy thrift, low error method to determine the suspended solid concentration of activated sludge
