Pottery sludge technology. In addition, in the case of ozone-treated water bodies, most of them are devices for injecting fluids into ozone (No. Patent No.), methods for controlling ozone concentration (No. 574, 152), and No. 1293286, and there is no technique for treating ceramics with ozone. The ideal environmental protection and cherish the limited resources of the earth, the best goal of returning to the factory for waste treatment, so if the ceramics can be ground to waste sludge, through the effective pre-treatment technology, 39136, and then return to the original process Or for other re-sharp, it will achieve the purpose of zero waste, capital and source reuse. SUMMARY OF THE INVENTION The main object of the present invention is to provide a method for treating a ceramic sludge, which can grind and dewater the ceramic slurry containing the ceramics produced by the pottery researcher. The mud is treated as fine mud and coarse mud for reuse, achieving the ideal environmental protection objective of "zero waste" and "reuse of resources". In order to achieve the foregoing objective, the method for treating a ceramic sludge provided by the present invention comprises at least the following steps: (4): separating a wastewater containing ceramic sludge into fine mud and coarse mud by using a rotary sieve device; Aeration treatment: The fine mud is placed in a closed reaction tank and • Ozone is fully aerated to decompose the organic matter of the fine mud Yin; Precipitate··Precipitate the sludge treated by ozone aeration; • Remove Moisture: dewatering or drying the precipitated fine mud; - Recycling · Recycling the coarse mud and the fine mud after removing the water. [Embodiment] Hereinafter, the second preferred embodiment of the present invention will be further described in detail with reference to the following: 1339136 First, please refer to FIG. 1 to FIG. 4, a ceramic sludge according to a preferred embodiment of the present invention. The processing method includes the following steps:

The first step of the present invention is the separation 110: the use of a rotary screen apparatus 10 to separate the wastewater containing ceramic fouling into fine mud-and-rough mud. The terracotta sludge ceramics grinds back, the rotary screen device 10 includes a susceptor 12, the susceptor 12 contains water therein; a rotating screen 14 is rotatably tilted s and placed on the susceptor 12 and partially immersed The water ring has a stainless steel support frame 141'. The support frame 141 is provided with a hollow cylindrical sieve body 142, which is a stainless steel fine mesh; a rotating shaft 143 passes through the central axis of the sieve body 142 and is fixed to the support frame 141. The sieve body 142 has a mesh aperture of ASTM 200 (75 micrometers) and an inclination angle of 5-20. The speed is 2 - 30 rpm and the height of the immersion water is ι/6 _ 1/2. The wastewater containing ceramic sludge is input into the rotary sieve 14 for separation, and the fine mud passing through the sieve hole is sludge having a particle diameter smaller than the sieve hole, and the coarse mud discharged through the rotary sieve 14 is sludge having a larger particle diameter than the sieve hole. . The second step of the present invention is ozone aeration treatment 12: the fine mud is placed in the -(4) type reaction tank 2G to sufficiently aerate with ozone to decompose the organic matter of the fine mud. The closed reaction tank 2A includes a tank body 22 into which the fine mud is fed, a plurality of hollow tubes μ, which are erected in the tank body 22, and ozone is introduced into each of the hollow tubes 2B4 to be sprayed into the tank. The body 22' is used to agitate the fine mud in the tank body 22 by the airflow to sufficiently react the fine mud with ozone, thereby decomposing the organic matter in the fine mud. The tank body 22 has a liquid-solid ratio of more than 3, and the ozone required per kilogram of dry fine mud is 1339136.2-10 g. In addition, the closed reaction tank 20 further includes an automatic pressure relief device 26, which is disposed on The trough body 22 is at the end. The third step of the present invention is the precipitation 130: precipitating the fine mud treated by ozone aeration, and depositing the fine mud in a sedimentation tank (not shown) by means of gravity sedimentation. - The fourth step of the present invention is to remove moisture 140: dewatering or drying the already degraded 'fine mud to remove moisture from the fine mud. The method of dehydration is to dehydrate the precipitated fine mud by means of pressure filtration, vacuum filtration or centrifugation, and the method of drying is to dry the precipitated fine mud by heating, and the heating temperature is 100-200 eC. The final step of the present invention is to reuse 150: the coarse mud and the dehydrated fine mud are recycled and reused, the coarse mud is used for concrete fine aggregate or other purposes, and the fine mud can be used as a part of the original ceramic process raw material or for use as a raw material. Other uses. It can be seen from the above that the treatment method of the ceramic sludge of the present invention can separate the wastewater containing the ceramic slurry produced by Tao Luqian into fine mud and coarse mud, and then aerate, precipitate and remove the fine mud by ozone. Moisture treatment, etc. The last two types of sludge can be reused as a “zero waste” and “resource reuse” environmentally innovative method. In addition, the general ceramics often have the problem that the stacked ceramics and the dewatered sludge are not easy to be treated, and can also be treated and reused by the method of the present invention. As shown in FIG. 5, it is a ceramic exemption of another preferred embodiment of the present invention. The sludge treatment method's steps are substantially different from the previous preferred embodiment: the steps of: the separation of 77, the ozone aeration treatment, the precipitation and the removal of moisture are different: before the separation step Including the following steps to judge 210. Whether to judge whether to insult the existing ceramics, grinding, dewatering and staining pottery factory, there is a pile of ceramics, grinding and dewatering sludge, and not holding other substances or being contaminated. The step of mixing the raw wastewater of the sludge; otherwise, no mixing is required. Mixed σ 220. The ceramic dewatered sludge and the raw wastewater containing ceramic sludge are mixed in a mixing tank (not shown), and the liquid-solid ratio system is greater than 3 after mixing. In this way, after mixing the ceramic grinding dewatered sludge accumulated in the ceramic factory with the wastewater containing the ceramic grinding sludge, the subsequent separation, ozone aeration treatment, sedimentation and moisture removal steps can be performed, and the coarse mud can also be processed. And the fine mud after dewatering is recycled and reused. In summary, the method for treating ceramic sludge of the present invention can treat the ceramic-containing grinding sludge wastewater generated by the ceramics factory and the stacked ceramic mortar and dewatered sludge into fine mud and coarse mud, and can be reused separately. The environmental protection effect of "zero waste" and "recycling of resources" is achieved; the reason is that the present invention does meet the requirements of the invention patent, and the application is made according to law 0 1339136.
