城市污水处理传统工艺的改进研究

Improvement of Traditional Technology for Urban Sewage Treatment

传统的污水处理工艺未对城市类型展开划分,降低了处理效率。为此,重点针对城市污水处理传统工艺进行改进。首先划分城市类型,从可持续发展的角度选择污水处理工艺流程。然后,结合不同类型城市污水处理需求,从污水处理过程能耗和物耗的角度,判断最优污水处理工艺的偏向性。然后在传统处理工艺的技术上,融入污水混合处理和浮选气浮工艺,有效扩大污水处理工艺的使用范围,并高效滤除污水中的杂质。实验结果表明改进后的处理工艺降低了处理成本,且提升了处理效率和处理后的污水利用率。

The traditional sewage treatment process does not divide cities into types,which reduces the treatment efficiency.The traditional process of urban sewage treatment is improved.Firstly,the city types are divided,and the wastewater treatment process is selected from the perspective of sustainable development.Combined with different types of urban sewage treatment needs,the bias of the optimal sewage treatment process is judged from the perspective of energy and material consumption of sewage treatment process.On the traditional treatment technology,the sewage mixed treatment and flotation air flotation process are integrated to effectively expand the application range of sewage treatment process and efficiently filter the impurities in sewage.The experimental results show that the improved treatment process reduces the treatment cost,and improves the treatment efficiency and sewage utilization rate.
