摘要
某县城区污水处理厂采用改良型Carrousel-2000型氧化沟为主的工艺,规模为1.0×10^4m^3/d。通过对实际进水水质和原有处理工艺处理效果充分的调查和分析,提出了对氧化沟提升改造和增加深化处理工艺采用"高密度澄清池+纤维滤布滤池"组合。该污水处理厂尾水水质指标全面达到《城镇污水处理厂污染物排放标准》(GB18918-2002)一级A标准。文本比较详细介绍了该污水处理厂的提标改造方案、主要构筑物的设计参数及工艺特点,以及处理效果等。
The improved Modified Carrousel-2000 oxidation ditch is adopted in a county Wastewater Treatment Plant with the water inflow of 1.0×104 m 3/d.Based on the investigation and analysis of the actual quality of the influent water and the treatment effect of the original treatment process,the advanced treatment process of upgrading the oxidation ditch and The combination of"high density clarifier+fiber filter cloth filter"is adopted.The water quality index of the tail water of the Wastewater Treatment Plant fully meets the class A standard of the"Discharge standard of pollutants for municipal wastewater treatment plant"(GB18918-2002).In this paper,the Wastewater Treatment Plant,the design parameters of the main structures,the process characteristics and the treatment effect are introduced in detail.
