ADVANCED ADULTERATION TREATMENT SYSTEM IN TREATMENT EFFICIENCY CAPABLE OF APPLYING TO WIDE WIDTH WATER PASSAGE

摘要

PURPOSE: An adulteration treatment system is provided to improve durability by increasing the rigidity of a screen, to make the water to be treated easily pass through the screen, and to improve treating efficiency. CONSTITUTION: In an adulteration treatment system(100), a screen device(40) and a breaker(30) are installed parallel in a state of crossing a water passage(10). The screen device collects adulterations in the water to be treated and transfers the collected adulterations to a direction of crossing the water passage. The breaker breaks the adulteration transferred by the screen device. The screen device has bar screens(45) of a fixed type and rakes(46). In the bar screen, the front side(45a) is formed in about a rectilinear shape with respect to the water passage, and the side(45b) of the breaker side connected to the front side is formed in a shape of guiding the adulterations to the breaker. The bar screens are arranged parallel in a vertically separated state. The rear of the bar screen is opened. The rakes are arranged parallel in a vertically separated state. Each of the rakes moves between meshes of the bar screen. The front end of the rake comes and goes from the outer periphery of the bar screen, rakes the adulterations collected to the bar screen, and transfers the adulterations to the breaker.
