Sewage Treatment Engineering Design And Research Of The Urban Waste Water Treatment Plant

In recent years, with the improvement of people’s living, sewage emissions continueto increase. Thanks to urban sewage treatment facilities dificiency, the urban sewagedirectly discharges into surface water, causing serious pollution. In this context, a townplans construction of a sewage treatment plant, and the engineering design focuses on therepresentative A/O off nitrogen removal process, oxidation ditch technology and SBRtechnology, a new sewage treatment technology analysis and demonstration, to the givensewage water quality data and natural conditions as the known condition, to therequirements of the water quality index for constraining conditions, screening for awastewater water quality the best processing technology.The engineering designs of size20000m3/d, and follows the strict accordance withthe relevant state laws and regulations and relavant standards implementation throughaccess to relevant information, and actively absorb domestic and foreign advanced sewagetreatment technology and equipment, integrated into the sewage treatment characteristics,greatly optimizing the process, using the Orbal oxidation ditch process, make CODremoval rate reach83%, the BOD removal rate reach89%, the removal rate of SS reach87%. After the treatment of sewage reached" urban sewage treatment plant pollutantdischarge standard" the level of B standard requirements. The implementation of theproject can greatly reduce the urban sewage discharge effects on the environment, theprotection of the environment. The discharged sewage after advanced treatment can reuse,for the community to save a lot of precious water resources. The project has a goodenvironmental benefits, economic benefits and social benefits.
