It is understood that the total investment of the project is 799,752,700 yuan, of which the estimated amount of the bidding is about 644,395,300 yuan, of which the estimated amount of the investigation fee is 2 million yuan, the estimated amount of the design fee is 17.387,200 million yuan, and the construction and installation engineering cost is estimated at 62500,81 million yuan.

Zhengyang sewage treatment Plant and sewage collection pipe network and recycled water utilization project in the East District of Qinhan New City in Xixian New District, a new underground sewage treatment plant is built, and supporting the construction of supporting sewage collection main pipe, tailwater drainage pipe and recycled water distribution main pipe. The total area of the sewage treatment plant construction land is 55.83 mu, of which the first phase covers 29.58 mu, including underground box, office building 1800 square meters, total power distribution room 336 square meters and other ancillary facilities. Sewage treatment scale of 40,000 m3/d recently (including 25,000 m3/d domestic sewage and 15,000 m3/d power plant wastewater). The total length of the new main sewage collection pipe is about 3203m, and the pipe diameter is d1000~1200. The d400 pre-buried sewage pipe is about 321m, and the d1200 pre-buried sewage pipe is about 553m. The total length of tailwater drainage pipe is about 550m, pipe diameter DN800; The total length of the reclaimed water distribution main pipe is about 10km, and the pipe diameter is DN600; The total length of the branch pipe is about 200m, and the pipe diameter is DN200. The two process routes of "pretreatment + improved A2O+MBR+ activated carbon adsorption process" and "pretreatment +DN+C/N+ high-efficiency precipitation + activated carbon adsorption process" are adopted for sewage treatment. The effluent quality standard is DB61/224-2018 standard A in the Comprehensive Discharge Standard of Yellow River Basin Wastewater of Shaanxi Province.
