冬季增加了内蒙古污水处理的难度,不利于污水处理的进行。因而进入冬季运行时应强化自身运行管理,应对冬季运行的不利因素,确保污水厂冬季高效运行,从而稳定达标、足额减排。在此结合以往进水情况和冬季运行的经验,总结以下运行办法,以强化和优化污水处理厂运行管理 ,确保足量处理污水、出水水质稳定达标。

冬季污水处理厂进水浓度普遍偏高、水温较低、活性污泥活性较弱,反应速度较慢,内蒙古污水处理厂需结合自身工艺和进水特征进行生产运行参数调整。

此时的污泥膨胀具有三个显著的特点:一是发生率极高,有60%的城市污水处理厂每年都发生污泥膨胀;二是普遍性,内蒙古污水处理开心彩票网在各种类型的活性污泥工艺中都存在,甚至最不易发生污泥膨胀的间歇式曝气池也发生了这一问题;三是危害严重,它不仅使污泥流失、出水悬浮物(SS)超标 ,而且还大大降低了处理能力。
