Experimental Research On An Integrative Equipment Purifying Raw Water Of Contact Filtration + Activated Carbon Adsorption+ UF

Water supply in town is absolutely necessary basic estabishment, in the course of the transmigrant' moving and construction in Three Gorges Reservoir Area. Taking into account about the tiny pollution of Three Gorges Reservoir Area, characteristic of economy, and characteristic of landform in Three Gorges Reservoir Area, it will have very important sense to exploit integrative equipment which can dispose drinking water to satisfy the demand of Three Gorges Reservoir Area, which request occupying smaller grounds, saving investment, operating easily, running fee low.The equipment of drinking water treatment contains three disposal cell main, which is contact filtration, activated carbon adsorption and UF in this researching and designing. The process and the design parameter of this equipment is analysed and explained in the thesis. At the same time, the course parameter, the operation and management of the equipment is also detailedly dissertated in the disposal of the raw water of The changjiang river(certain spot of taking water in ChongQing) with this equipment, and the experiment context includes the disposal effect of the raw water under the design flow and UF facilities'pollution and clean during the disposal process.The design flow of the equipment is 1m³/h. Under the experimentation, the outflow index: the turbidity is 0.08-0.12NTU, COD_Mn is less than 0.5mg/l, NH₃-N is less than 0.5mg/l, TOC is 0.073⁰.232mg/l, the quantity of bacteria is 0; the removal efficiency of turbidity beyond 99%, the removal efficiency of COD_Mn between 77.30% and 82.80%, the removal efficiency of NH₃-N between between 40.00% and 92.75%, the removal efficiency of TOC between 81.95% and 94.03%, the removal efficiency of bacteria neally get to zero. This several water quality indexes of outflow is accord with water quality standards of drinking water, so this equipment can adequately guarantee the security and sanitation of drinking water of the Three Gorges Reservoir Area people.The pollution and cleaning instants of UF equipment are measured and calculated during the experimentation. The maximum water outflow of UF equipment is 16.5L/min, the physical rinse is needed when water outflow of UF equipmen drops about 13 L/min, the chemic rinse is needed when water outflow of UF equipmen drops about 12L/min. the physical rinse cycle of UF is three days, the chemic rinse cycle is about one month, the removal efficiency of membrane flux is 95.7% by physics rinse...
