Commissioning And Operation Of A~2/O In Town Wasterwater Treatment Plant

Water is essential to sustain life and physiological activity of substances, but also human to positive social and economic activities essential to the material, their needs as human social and economic activities, development and human living standards and increasing Sheung Shui, the Earth's reserves are limited, water is not new, and only through a cycle and regeneration. The nearest available municipal sewage, water quantity, water quality is relatively stable, after appropriate treatment to reuse is a good way to solve the water shortage. Therefore, urban sewage treatment works into a modern city looking for a second supporting construction of water infrastructure.Urban sewage treatment plant complex process, involving many of the supporting facilities, in order to achieve a certain effluent water quality standards, we must conduct a continuous record of debugging and tracing, and analysis, so the debugging process is the sewage treatment plant effluent quality necessary to achieve the desired an important part.This is the county town of sewage treatment plants should be A2/O process as the research object is running on the effluent quality standards for wastewater treatment plant upgrade, debug study. The impact on water quality are many, of which the most important in the technological aspects of the biological reactor, which is the anaerobic tank, anoxic, aerobic pool. Return mixture has 2Q, no debugging. Mainly the concentration of activated sludge, dissolved oxygen for debugging.The commissioning started from July 2010, after 2 months. From September 2010-January 2011 track record, operational data is not ideal in the winter than ammonia, other indicators of the water can reach the standards. COD, BOD, SS, TP from September 2010-January 2011, the average removal rate was 93%,96%,96.5%, 90.5%. A2/O process debugging problems and solutions, as a theory and practice of. In July the county should be the hottest, the coldest in January. The commissioning experience from the hottest to the coldest a process. A2/O process of the aerobic pond aeration devices used in oxygen through activated sludge and dissolved oxygen concentration of debugging, the colder the winter the temperature should be the county town of the sewage treatment plant effluent quality can achieve the desired treatment effect. After six months of debugging and tracing sewage treatment plant effluent quality is relatively stable.In the A2/O process is running, should pay attention to deal with structures and equipment maintenance work, and to properly maintain records of the archive. For the wastewater treatment plant staff, to ad hoc training. Sewage entering the plant, changes in water quality and quantity to make their daily water quality testing and analysis, and complete record keeping various types of information, and to adjust operating conditions.According to this thesis, the problems encountered in running debugging, put forward several suggestions. Then run the plant costs and benefits of doing analysis, and will be built for new sewage treatment plant operation and management of personnel information.
