Water purification plant reconstruction project of a city in Heilongjiang Province 

Water purification plant reconstruction project of a city in Heilongjiang Province

Water volume: 40000m3/d

Raw water: river water

Raw water turbidity: 150-300NTU

Outlet water of sedimentation tank before transformation: 10NTU

Filtered water: 5NTU

Effluent from the reformed sedimentation tank: 3NTU

Filtered water: ≤ 1NTU

The process adopts high-density mixer+high-density micro vortex flocculation sedimentation tank+ordinary fast filter

Project introduction: The project is a municipal water purification plant upgrading and reconstruction (PPP) project, including the reconstruction of flocculation sedimentation tank and water collection equipment, the construction of a 40000 m3/d membrane treatment room, two 3000 m3 clean water tanks, one 800 m3 intermediate regulating tank, and one 500 m3 wastewater regulating tank. Total equipment investment: 21.65 million yuan. After transformation, the effluent is stable below 0.5NTU.
