SBR处理器(国外英文资料) Overview of SBR sewage treatment process SBR is Sequencing Batch activated sludge Process (Sequencing Batch Reactor Process) for short, is a kind of intermittent aeration way operation of the activated sludge wastewater treatment technology, also known as Sequencing Batch type activated sludge Process. Unlike traditional wastewater treatment process, SBR technology USES time division operation way alternative space division way of operation, unstable and biochemical reaction instead of steady state and biochemical reaction, let stand ideal replacement of traditional dynamic precipitation precipitation. The main characteristic of it is on the run orderly and intermittent operation, the SBR technology is the core of the SBR reaction pool, the pool set homogenization and initial setting, biodegradation, two functions in a pool, no return sludge system. The SBR has the following advantages: The ideal push-flow process makes the biochemical reaction force increase, the efficiency is improved, the oxygen in the pool, the good oxygen is in alternate state, the purification effect is good. The operating effect is stable, the sewage is settled in the ideal stationary state, it will take short time, high efficiency and good water quality. The impact load of the water in the pool is affected by the shock load, and the water can be diluted and buffered, which is effective against the impact of water and organic waste. The various processes in the process can be adjusted according to water quality, water quantity, and be flexible. Low processing equipment, simple construction, easy operation and maintenance management. The concentration gradient of DO and BOD5 is present in the reaction pond, which effectively controls the expansion of activated sludge. The SBR system itself is also suitable for the construction method of combinatorial structure, which is beneficial to the expansion and modification of wastewater treatment plants.
