七十年代引进的武钢1700轧机、上海石化总厂化工二厂、涤纶厂、辽阳石化厂、天津大港电广以及辽河化肥厂等成套项目中都附有水处理工程。这些水处理设施的机械设备选用定型产品。这样既加快工程进度,又保证产品质量。现就预处理设备、排泥除砂、浓缩撇油、提升设备、曝气机械、污泥处理、自动取样和管道配件等几个方面加以介绍。1.预处理设备天津大港电厂是从意大利引进的60万千瓦热电站。在取水口设有机械格栅和回转滤
The water treatment project was included in the 1700 rolling mill of Wuhan Iron and Steel Company, the second chemical plant of Shanghai Petrochemical Plant, the Polyester Plant, the Liaoyang Petrochemical Plant, the Tianjin Dagang Dianguang Plant, and the Liaohe Chemical Fertilizer Plant. The mechanical equipment of these water treatment facilities is selected and shaped. This will not only speed up the progress of the project, but also ensure product quality. The pretreatment equipment, sludge removal, sand enrichment, lifting equipment, aeration machinery, sludge treatment, automatic sampling and pipe fittings are introduced in several aspects. 1. Pretreatment equipment Tianjin Dagang Power Plant is a 600,000 kilowatt thermal power station imported from Italy. In the water intake with mechanical grille and rotary filter
