摘要
为了缓解烟台市水资源紧缺的局面,满足万华工业园百万吨大乙烯建设及烟台发电厂等项目对再生水的需求,实现水资源的合理利用,开展了套子湾污水厂再生水回用工程建设。一期新建规模为5×10^(4) m^(3)/d,利用污水处理厂原有反渗透设施,一期工程建成后再生水总规模达到10×10^(4) m^(3)/d。再生水进水来源为套子湾污水厂出水,进水水质执行《城镇污水处理厂污染物排放标准》(GB 18918—2002)一级A标准。基于进水水质特点和出水使用要求,采用超滤+反渗透再生水回用处理工艺。建成后出水水质优于《城市污水再生利用工业用水水质》(GB/T 19923—2005)各项指标要求,出水浊度平均值为0.3 NTU,TDS平均值为110 mg/L。
A reclaimed water reuse project in Taoziwan wastewater treatment plant was constructed to realize rational utilization of water resources.The project is expected to alleviate the shortage of water resources in Yantai and meet the demand of reclaimed water for one million tons of ethylene construction project in Wanhua industrial park,Yantai power plant and other projects.The new scale of the phase I project is 5×10^(4) m^(3)/d,and the total scale of the reclaimed water plant after completion of the phase I project will reach 10×10^(4) m^(3)/d by utilizing the original reverse osmosis facilities of the wastewater treatment plant.The water source of the reclaimed water plant is the effluent from Taoziwan wastewater treatment plant,and the influent water quality needs to meet the first level A criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002).Based on the characteristics of the influent quality and the utilization requirements of the effluent,a combined process consisting of ultrafiltration and reverse osmosis was eventually determined.After completion of the project,the effluent quality is better than the requirements of The Reuse of Urban Recycling Water—Water Quality Standard for Industrial Uses(GB/T 19923-2005),and the average turbidity and TDS in the effluent are 0.3 NTU and 110 mg/L,respectively.
