    • PROBLEM TO BE SOLVED: To provide a water treatment method capable of effectively performing water treatment of water to be treated which contains ferrous ions.
      SOLUTION: The water treatment method includes: a first step of oxidizing the ferrous ions contained in the water to be treated; a second step of giving carriers into the water to be treated, depositing iron oxyhydroxide after oxidation onto surfaces of the carriers and stripping the iron oxyhydroxide from the surfaces of the carriers by means of flow of the water to be treated; a third step of injecting an inorganic coagulant into the water to be treated; a fourth step of quickly stirring the water to be treated; and a fifth step of introducing the water to be treated into a sedimentation pond involving an upward stream and causing the water to be treated to pass between a plurality of inclined plates arranged in routes of the upward stream.

    • PROBLEM TO BE SOLVED: To provide a coagulation treatment method of water to be treated, and its treatment apparatus. SOLUTION: The method comprises: the injection of the coagulant into the water to be treated or treated water after flowing into a rapid agitation tank carrying out the rapid agitation when coagulation treatment is carried out by rapid agitation pouring a coagulant in the water to be treated and flocculation without pouring the coagulant; the execution of rapid agitation treatment providing the intensity of rapid agitation (G R value) of 450 sec -1 or higher; and next the execution of coagulation treatment by providing the intensity of flocculation agitation (Gs 1 value) of 75 sec -1 or higher in a first tank located on the most upstream side of a flocculation in a flocculation tank including a plurality of tanks and also the intensity of flocculation agitation (Gs 2 value) after a second tank. This method has the advantage of yielding settled treated water having turbidity lower in one order than a conventional method, and enabling a reduction in danger of a leak of protozoa oocysts or the like in filtrate.

    • PROBLEM TO BE SOLVED: To provide a new concept of coagulating sedimentation treatment and a concrete coagulating sedimentation method and apparatus for realizing it in order to optimize the entire system including the following filtration treatment and sludge treatment. SOLUTION: A tilting device 8 having a small mounting pitch is used in place of a conventional coagulating sedimentation method in which an agglomeration method having a low agitation intensity is selected for avoiding floc breaking to realize high efficient agglomeration of particles having a diameter of ≤3.0 μm and making fine flocs high density in a fine floc generation process on condition that outflow of fine flocs having a diameter of ≥3.0 μm, which are broken pieces after the floc breaking, is obstructed. A coagulant injection rate is controlled so that the STR of a floc generation process inlet 201 is set at minimum requirement to minimize the amount of outflow fine flocs into settled water while maintaining flocs to be settled and separated and fine flocs flowing out into a filter basin in a state of fine particulates and high density.
