処理方法に関する。DETAILED DESCRIPTION OF THE INVENTION This invention uses granular incineration ash containing 20 to 30% of volatile substances as a waste material, and is particularly suitable for use in the human waste treatment process.
The present invention relates to a human waste treatment method that can efficiently remove CODMn and chromaticity components at the same time as removing SS from subsequent treatment water or coagulation-sedimentation treatment water.

般的であるが、ＣＯＤＭｎや色度成分を除去することが
できないという点で満足すべきものとはいえない。The most common filtration device for removing SS from treated water in the human waste treatment process is one that uses sand as the filtration material, but it is unsatisfactory in that it cannot remove CODMn and chromaticity components. It cannot be said that it is something that should be done.

を目的としている。If activated carbon is used as a counterfeit material, the removal effect of CODMn etc. will be greatly improved, but the cost of activated carbon is prohibitively high, making it economically difficult to use it on an industrial scale. An object of the present invention is to provide a method for treating human waste using a novel filtration material that can effectively remove CODMn, which cannot be removed with sand filtration material.

捕捉を主とする猿過が行われる。A water-permeable support 2 is provided in the sieve tank designated by reference numeral 1 in the figure at a predetermined height above the bottom of the tank.
is provided, and on this support 2, a support material layer 3 such as reki is provided.
and the oak layer 4 are supported. This oak layer 4 is made of V
It consists of granules of surplus sludge incineration ash that have been incinerated so that M is 20 to 30%. Further, above the oak layer 4, a trough 5 for raw water inflow is provided. On the other hand, a chamber 6 for receiving liquid is formed below the support 2, and the liquid that has flowed into the chamber 6 is discharged to the outside through a pipe 8 having a valve 7. There is. There is no backwashing equipment like a regular filtration system, and once it becomes saturated, it is incinerated again. The oak layer 4 has a diameter of 2 containing 20-30% VM.
This layer consists of surplus sludge incineration ash in the form of granules of 1 to 3 skins, and while the raw water flowing down from the trough 5 passes through this oak layer 4, filtration is performed mainly to capture SS.
