- Abstract:
- The total capacity of the first and second stage of Yantai Taoziwan wastewater treatment plant (WWTP) is 35×104 m3/d, and the effluent meets the first level A criteria of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). It has played an important role in improving the urban sewage treatment rate and reducing coastal pollutant discharges. On the premise of ensuring stable and qualified effluent, this project fully utilizes the chemical energy in the sewage to achieve partial self-sufficiency of power energy in the factory. It fully utilizes the thermal energy contained in sewage for heating inside the factory and providing heat sources to residential areas outside the factory, so as to reduce the consumption of fossil fuels. It also fully improves the utilization rate of reclaimed water resources, thus to save an equal amount of tap water resources. These practices in this project have achieved good results in sewage reclamation, energy conservation and discharge reduction.
