質が低下することがあった。In the above-mentioned conventional method for treating water containing organic substances, when raw water contains manganese ions, permanganate ions may be generated from the manganese ions by ozone treatment. . That is, manganese ions are first converted into insoluble manganese dioxide by the oxidizing action of ozone, but when the oxidation reaction further proceeds, they become permanganate ions. Permanganate ions cannot be removed by activated carbon treatment, and cannot be removed by membrane filtration because of their solubility. Therefore, when water containing organic matter and manganese ions is treated by the above-mentioned conventional treatment method, permanganate ions may leak into the treated water after the membrane filtration treatment, and the treated water quality may be reduced.

ないおそれがあった。On the other hand, in order to suppress the permanganate ion from being generated by the peroxidation of manganese ion, it is conceivable to reduce the ozone injection rate in the ozone treatment or shorten the treatment time. However, when these means are adopted, there is a possibility that the objective effects of decomposing and modifying organic substances in the ozone treatment may not be sufficiently obtained.

とを防止することが可能となる。In the present invention, first, in the biological activated carbon treatment means, organic substances contained in the water to be treated are decomposed and removed by the action of microorganisms, and manganese ions are oxidized to insoluble manganese dioxide and removed ( See below). Therefore, before the ozone treatment, the concentrations of organic substances and manganese ions in the water to be treated are reduced in advance. Therefore, in the next ozone treatment means, since it is only necessary to remove the organic matter whose concentration has been reduced in advance, the injection rate of ozone can be reduced, and the treatment time can be shortened. Also, organic substances can be efficiently removed. Further, since the ozone treatment conditions can be relaxed as described above, manganese ions remaining in the treated water of the biological activated carbon treatment means can be oxidized to manganese dioxide while suppressing peroxidation of manganese ions. Therefore, according to the present invention, it is possible to efficiently remove organic substances and manganese ions contained in the water to be treated, and to prevent permanganate ions from leaking into the treated water after the membrane filtration treatment.

てもよい。Hereinafter, the present invention will be described in more detail. In the treatment apparatus of the present invention, first, the biologically activated carbon is treated by the biologically activated carbon treating means. Biological activated carbon is obtained by attaching microorganisms to the surface or pores of activated carbon. Among these microorganisms, there are microorganisms that decompose organic substances and microorganisms that oxidize manganese ions to manganese dioxide. Therefore, organic matter and manganese ions contained in the water to be treated can be removed by the biological activated carbon treatment. Biological activated carbon can be obtained by passing appropriate water through ordinary activated carbon for a predetermined period of time and allowing microorganisms to propagate on the surface or in the pores of the activated carbon. Further, depending on the quality of the raw water, a pretreatment facility such as a coagulation treatment facility may be added before the biological activated carbon treatment means.

As a result, decomposition and reforming of organic substances, specifically, decomposition of hardly biodegradable organic substances and modification to easily biodegradable organic substances are performed. The ozone treatment can be performed by adding ozone to the water to be treated. In this case, the means for adding ozone to the water to be treated is not limited, and for example, a counter-current bubble column using a diffuser plate, a gas-liquid stirring and mixing means, and the like can be used.

As a result, insoluble substances, suspended substances, bacteria, protozoa and the like contained in the above treated water are removed. Further, manganese dioxide generated by the biological activated carbon treatment means and the ozone treatment means is also removed by the membrane filtration treatment means.

水を得ることができる。In the treatment apparatus of the present invention, an activated carbon treatment means can be provided between the ozone treatment means and the membrane filtration treatment means as required. That is, when a membrane made of a material that is easily oxidized to ozone is used as the membrane of the membrane filtration unit, an activated carbon treatment unit is installed in front of the membrane filtration unit, and ozone in water is removed by the activated carbon treatment unit. Thereby, protection of the membrane of the membrane filtration means can be achieved. In addition, since the organic matter in the water is removed by the activated carbon treatment means, it is possible to obtain treated water having a further reduced organic matter concentration. If a membrane made of a material that is not easily oxidized by ozone is used as the membrane of the membrane filtration means, the activated carbon treatment means may be installed at a stage subsequent to the membrane filtration means, thereby further reducing the organic matter concentration. The treated water can be obtained.
