The present invention relates to a new steelmaking wastewater treatment equipment that enables the cyclical reuse of wastewater. Industrial wastewater used as cleaning water or cooling water in the forming process of steel bars, steel plates, etc. contains a large amount of scale, sludge, etc., and such wastewater is not directly discharged outside the factory. or cannot be reused as industrial water. However, in order to discharge water or reuse it, it is necessary to remove mixed scale and sludge.
Removal of scale and removal of sludge require separate treatment methods, and conventionally each was treated in separate processes, which of course complicates the treatment process and requires a lot of space for treatment facilities. There were flaws.

The figure is an explanatory view of one embodiment of the iron-making wastewater treatment apparatus of the present invention. Factory wastewater used as cooling water or washing water in the iron manufacturing process (not shown in the figure) is sent to the apparatus through a branch pipe 1 as shown by the arrow. Reference numeral 2 denotes a separation tank, which is formed integrally with the rear coagulation tank in the shape of the bottom of a ship, and the bottom of the ship is provided with one common screw conveyor 11 that extends to the bottom of the rear coagulation tank. In the separation tank, the scale mixed in the industrial wastewater settles downward due to its own weight and slides along the swash plate 12 shaped like the bottom of a ship.
The screw conveyor 11 is separated from the waste water by its rotation, and transported to the scale storage tank 1.
It is discharged at 3.

放出又は工業用水として循環再使用される。 The separation tank 2 connects to the downstream first coagulation tank 3 via the weir 16.
and is continuous to the second coagulation tank 5. The wastewater that has flowed into the first flocculating tank 3 through the weir 16 is fed to the flocculant supply pipe 1
The flocculant is added through the partition wall 17 and the rapidly rotating rapid stirrer 4 promotes complete mixing of the waste water and the flocculant.
It is sent to the next secondary coagulation tank 5 through a passage provided below. In the second flocculation tank, the flocs are agitated by a low-speed stirrer 6 that rotates at a low speed to form flocs. A screw conveyor 11 extends from the bottom of both the first flocculation tank and the second flocculation tank, and the sinking foreign matter is separated and discharged thereby. The floc is an aggregate of magnetic sludge and non-magnetic sludge, and its formation is promoted by the low-speed stirring of the stirrer 6, and the generated floc floats to the surface of the waste water.
The flocs are attracted to the surface of the magnetic disk of the magnetic rotation separator 7 located downstream and separated from the waste water. The adsorbed flocs are conveyed to the rotating magnetic disk and then discharged to the sludge storage tank 10 through the chute 9. The cleaned wastewater is discharged through the drain pipe 14 and discharged outside the factory or recycled and reused as industrial water.
