Reconstruction Technique Tangshan City A Water Purification Plant To Enhance Water Quality

In recent years,China?s industrial and agricultural development is rapid,the country?s water resources suffered different degrees of pollution,the previous drinking water has become a micro-polluted water source,at home and abroad micro-polluted water source water quality improvement transformation of the main technical measures are: Add pre-processing,to strengthen the conventional processing and increase the depth of treatment.Tangshan City,a water treatment plant in Tangshan City,the vast majority of residents living water and industrial enterprises water,due to Douhe River water to a certain degree of pollution,water purification water quality has been difficult to meet the latest national water quality standards.Based on the advanced experience of upgrading the water quality of micro-polluted water plants at home and abroad,this paper puts forward the following water quality upgrading technology: the increase of the water intake project of the water purification plant Potassium permanganate pre-oxidation measures;the original process grille flocculation inclined tube sedimentation tank into aeration flocculation high-density sedimentation tank;the original process double valve filter into submerged ultrafiltration membrane pool;The process is a high-density coagulation sedimentation + bio-charcoal activated sludge refluxing + ultrafiltration process,the use of bio-active sludge and biological powder activated carbon biological action to remove trace organic matter,the use of ultrafiltration superior mechanical retention effect,high precision removal of insoluble Particulate matter,including turbidity,bacteria,viruses,water supply to ensure water quality and improve water quality for Tangshan City,industrial and commercial users and the people to provide safe drinking water.The successful experience of the project can also provide reference for the upgrading of other micro-polluted water source waterworks in Tangshan City.
