【摘要】 介绍了曝气自清洗式回流污泥细格栅的工作原理、装置结构、运行参数以及运行效果。结果表明曝气自清洗式格栅可以外接于回流污泥系统;曝气清洗的方式可以有效的将拦截物从栅板上吹脱并推入栅渣网内:不同孔径栅板均可拦截下定的杂质,3mm孔径栅板效果较5mm孔径栅板效果高80%～100%。更多还原

【Abstract】 The working principle,device structure,operating parameters and operating results of the Automatic Aeration Cleaning Screen for the returned sludge are intruduced.And the results show that the Automatic Aeration Cleaning Screen can externally link up with the returned sludge system,the way of the aeration cleaning can effectively blow off the intercepted stuff from the screen panel and push them into the slag screen net,and all the screens of different aperture can intercept under certain amount of impurities,as a result of that, the effect of the 3mm aperture screen is 80%to 100%higher than the 5mm aperture one.更多还原
