摘要
文章针对北方寒冷地区污水处理厂冬季运行是受温度影响方面,以典型的生化处理工艺为例,从微生物生长、生化反应速度等机理出发,分析低温对微生物生长、酶促反应速度、生物处理反应速度、生物脱氮、沉淀装置的各种影响,经分析表明:当水温低于13℃时,生物处理效果开始加速降低,污水处理站的污水处理效率降到了50%左右,当水温低于4℃时,几乎无处理效果,同时低温会导致污泥膨胀等现象出现。最后,文章推荐几种解决上述问题的技术途径。
As the temperature affects wastewater treatment plant in the North, taking the typical technices biological treatmentthe for example, writers discuss the effect of the different temperature, from enzyme, biochemical response speed and so on. The analysis result is that when the water temperature is below 13℃ ,the biological effect becomes decreasing,the wastewater plant effect is about 50% and when the water temperature is below 4℃ ,there is no any effect, at the same time, the low temperature can cause the sludge to inflate. Finally, some measures are recommended to resolve the mentioned problem.
