摘要
兴隆堡污水处理厂工程设计规模2×10^(4)m^(3)d,冬季水温10℃。该厂采用多点进水A2O工艺,此工艺处理效果稳定,可调性好,且运行方式比较灵活,能很好的适应东北地区冬季低温环境,出水达到《城镇污水处理厂污染物排放标准》(GB 18918-2002)中的一级B标准。文章介绍了该工程的工艺流程、设计参数和技术特点。
The recent treatment capacity of Xinglongpu Sewage Treatment Plant is 2× 10^(4)m^(3)/d,and sewage temperature in winter is 10℃. The secondary biochemical treatment adopts the Multi influent A^(2)O process which has the flexible operation.The process adapts well to the winter low temperature in the northeast area.The process can operate steadily under low temperature condition,and the effluent quality meets the first class B criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002).The process flow,design parameters and technical characteristics of the project were introduced.
