【摘要】：依据我国村镇污水处理的技术要求及村镇污水水质、水量特点,提出了一种新型一体化装置。该装置采用活性污泥法与厌氧/缺氧相结合,并运用一体化的设计理念,集好氧、缺氧、厌氧于同一反应池。通过模拟村镇污水的运行,研究了新型一体化装置曝气/搅拌交替运行的最佳条件。结果表明:在水力停留时间为6 h,当曝气/搅拌交替运行的循环周期和时间比例分别为120 min和40∶80条件下,装置能同时实现对COD、TN、TP的去除,COD、TN、TP的平均去除率分别为86.1%、84.3%、77.4%,且出水水质保持稳定,出水COD、TN达到GB 18918—2002《城镇污水处理厂污染物排放标准》一级A标准,出水TP达到一级B标准。
[Abstract]:According to the technical requirements of wastewater treatment in villages and towns in China and the characteristics of water quality and quantity of wastewater in villages and towns, a new type of integrated device is put forward, which combines the activated sludge process with anaerobic / anoxic process, and uses the integrated design concept to collect aerobic. Anoxic, anaerobic in the same reactor. By simulating the operation of village sewage, The optimum conditions for alternating aeration / stirring operation of a new integrated device are studied. The results show that under the condition of 6 h HRT, the cycle cycle and the ratio of time to time are 120 min and 40: 80, respectively. At the same time, the average removal rate of COD ~ (2 +) -TNT _ (TP) is 86.1 and 84.3n / 77.4 respectively, and the effluent quality is stable. The effluent COD _ (TN) reaches the first class A standard of GB 18918-2002, and the effluent TP is up to the first class B standard.
