2) sludge deposit
污泥沉积
1.
During the operation of improved Carrousel oxidation ditch,there exist problems including sludge deposit,low efficiency of nitrogen and phosphorus removal,inflexible control of sludge return ratio.
改良型Carrousel氧化沟在实际运行过程中存在污泥沉积严重、脱氮除磷效果不佳、污泥回流比的控制不够灵活等问题,采用扩容选择池、氧化沟内增加潜水推流器、安装回流污泥计量装置等方式进行技术改造,彻底解决了积泥问题,提高了脱氮除磷效率,并节省了大量能源,降低了生产成本,使系统实现良好的运行状态。
2.
However,there are such problems as too low TN and TP removal rate,sludge deposit in the bottom of oxidation ditch,and sludge expansion during the operation of the oxidation ditch.
但同时存在总氮,总磷处理能力较差,不能达到国家排放标准;污泥沉积严重,较大地影响了氧化沟有效容积以及产生污泥膨胀等问题。
3) sludge deposition
污泥沉积
1.
Aimed at the complex flow regime of the oxidation ditch bend,the effect of transverse circulatory flow and redistribution of velocity at the bend on sludge deposition was analyzed.
针对氧化沟弯道水流流态复杂的特点,分析了弯道横向环流和水流流速在弯道的重新分布对污泥沉积的影响,借助ANSYS FLOTRAN模块对设置偏置导流墙前、后的水流流速分布情况进行了模拟比较,探讨了偏置导流墙减少污泥沉积的机理,并研究了氧化沟弯道局部阻力和边墙超高的计算方法,从而为导流墙的设计提供参考。
4) sludge bank
