摘要
以实际污水处理厂沉砂池出水为研究对象,检测分析了低温运行条件下微孔曝气氧化沟中试装置脱氮除磷效果随温度的变化情况。结果表明,水温低于11℃时,试验装置的脱氮除磷效果明显变差,并分析了硝化和反硝化效率不高的原因,提出了相应的运行调整措施与建议,其结论对同类型污水处理厂的运行管理有参考价值。
Taking the actual effluent of wastewater treatment plant as the research object,analyzed the nitrogen and phosphorus removal changed with temperature of pilot equipment of oxidation ditch under microporous aeration operation at low temperature..The results showed that：when the water temperature below 11 ℃,nitrogen and phosphorus removal of the pilot-scale oxidation ditch was significantly worse,the research has analyzed the denitrogenation efficiency not high reason in oxidation ditch,proposed the corresponding operation measure and the suggestion.The author hoped the conclusions may be valuable to operation and management for similar Wastewater Treatment Plants.
