| 摘 要： | 通过分析厌氧处理系统VFA碱度和H2 CO3 碱度的变化特点 ,指出厌氧处理系统所需VFA碱度与运行方式、运行控制、水质、温度等因素有关 ,良好运行的厌氧系统所需碱度主要是H2 CO3 碱度 ;高效吹脱的厌氧系统所需H2 CO3 碱度很小 ,尤其是低浓度废水可通过选择投加碱度的种类以吸收CO2 或通过CO2 气相控制等手段将H2 CO3 碱度降至最小。

| Abstract: | The paper analyses the changing of VFA alkalinity and H 2CO 3 alkalinity and pointes out that VFA alkalinity is concerned with process configuration, process control and water character and so on, the alkalinity requirement in stabilized anaerobic system is the H 2CO 3 alkalinity. The anaerobic system with efficient stripping will have very little requirement for H 2CO 3 alkalinity, H 2CO 3 alkalinity can be decreased to least through choosing supplemental alkalinity to absorb CO 2 or through controlling of CO 2 gas phase especially in diluted effluent treatment. |
