- Abstract:
- 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 5×104 m3/d, and the total scale of the reclaimed water plant after completion of the phase I project will reach 10×104 m3/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.
