A lab-scale study on completely-mixed activated sludge aeration tank in-series ( CMAS in-series) treating pharmaceutical wastewater from a Harbin pharmacy plant was conducted to optimize the practical full-scale plant operation parameters and to explore the removal of various pollutants. 通过小试模拟完全混合推流式活性污泥曝气池(串联CMAS工艺)处理哈尔滨某制药生产废水,优化实际工程的工艺运行参数,研究各污染物在系统中的去除特性。
According to this situation, the cultivation of activated sludge in SBR aeration tank is classified into two stages: the first stage, making sludge adapt to leather making wastewater and making it have high removal rate to COD; 针对这种情况,把SBR曝气池活性污泥的培养分为2个阶段,第1阶段使污泥适应此制革废水,并使其对COD有较高的去除率;
The simulation and the model of activated sludge process reactor with secondary settling tank 活性污泥过程反应池与二沉池耦合模型与模拟
In comparison with the activated sludge process, BAF has higher organic volume load based on secondary oxidation biological processes with low organic concentration, shorter stopping time for wastewater and without secondary sedimentation tank. 它与活性污泥法工艺相比,对于低基质污水二段生化工况,其有机物容积负荷高,污水停留时间短,其后不须设置二次沉淀池。
Compared with traditional activated sludge system, the main advantages of BAF has stronger treating capacity, better treating effect, less relationship with temperature, higher capacity for absorbing shock load, no requirement for secondary settlement tank, simpler technology flow and more reasonable bacterium structure. 与传统活性污泥法相比曝气生物滤池具有处理能力强、处理效果好、受气温影响小、耐冲击负荷、不需二沉、工艺流程简单和菌群结构合理等优点。
The activated sludge technology is a major technique for sewage treatment. Medium sludge load and continuous push flow aeration tank are adopted in the traditional activated sludge technology. 活性污泥工艺是污水处理的主要工艺,传统的活性污泥工艺采用中等污泥负荷,曝气池为连续推流式。
