Separation technology of insoluble contaminants refers to a method of separating and removing insoluble suspended solids (including oil films, oil products) in sewage by physical action, and is generally called solid-liquid separation. The equipment is simple in most of the use, convenient to operate and extremely wide in use. In the solid-liquid separation process, two main categories can be distinguished according to the principle involved in the separation: one is that the liquid phase is limited, and solid particles can move freely in suspension, and can be classified into centrifugal sedimentation, gravity sedimentation or floatation; another class is the use of media that have solid particles confined to allow the liquid phase to pass through the media, which can be categorized as screen retention, filtration, and the like. The rotary grid sewage remover is a special water treatment device capable of continuously and automatically intercepting and removing sundries with various shapes in fluid, and can be widely applied to urban sewage treatment. The water inlet of tap water industry and power plant can be used as the front-stage screening equipment in wastewater treatment processes in textile, food processing, papermaking, leather and other industries, and is one of the most advanced solid-liquid screening equipment in China at present. The grid trash remover is a group of rotary grid chains assembled by a unique toothed harrow factory. The toothed harrow chain is driven by the motor reducer to rotate in the reverse water flow direction. When the toothed harrow chain runs to the upper part of the equipment, the relative self-cleaning motion is generated between each group of toothed harrows due to the guidance of the grooved wheels and the bent rails, and most of solid matters fall down by gravity. And the other part cleans sundries stuck on the toothed harrow by means of the reverse movement of the sweeper.
