- Abstract:
- A reclaimed water reuse project with designed treatment capacity of 6 500 m3/d, which serves seven water-jet loom enterprises in a county, adopts the process of screen, coagulation flotation, and biological aerated filter. Twenty percent of the reclaimed water is exchanged with the effluent of the wastewater treatment plant(WWTP), and the oily sludge is centrifugally dehydrated to eliminate pollutant enrichment during reclaimed water cycling. Practice has proved that the quality of reclaimed water treated by this process can meet the demand of water-jet loom, which greatly reduces the water treatment load of the original centralized WWTP. Thereby the effluent of the WWTP reaches the discharge requirement of first level A criteria in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002).
