摘要
针对寒冷地区污水厂启动困难、时间长的难题,在哈尔滨太平污水厂启动过程中,首次采用活化菌液、生物菌剂与活性污泥同时投加的生物强化技术,在平均气温为10℃、生化池进水温度为13℃的低温条件下,采用先异步后同步的复合培菌方法,成功进行了AO池活性污泥的培养驯化。从第12天开始,在超越初沉池的情况下AO池满负荷运转,且各项出水水质指标均优于设计目标。
Because the wastewater treatment plant （WWTP） in cold area is difficult to start up with long time to be taken, the bio-augmentation technology with simultaneous addition of activated liquid strain, biological bacterial agent, and activated sludge into AO basin was firstly adopted in the start-up of Harbin Taiping WWTP. Under the low temperature with the average of 10 ℃ and influent temperature of 13 ℃, use of the asynchronous followed by synchronous culture method succeeded in acclimated culture of activated sludge. After 12 days, AO basin operated at full loading under the condition of bypassing the primary clarifier, and all effluent indexes were better than the designed ones.
