| description | The invention relates to the technical field of environmental protection devices, and discloses a sewage purification method for reducing constructed wetland greenhouse gas emission, which is characterized in that sludge taken from municipal sewage is subjected to pulverization treatment by adopting an impurity removal, drying and grinding device. And heating the sludge powder to 600-800 DEG C in a muffle furnace with N2 as a protective gas at a heating rate of 10-20 DEG C/min, keeping the temperature for 3-6 hours, cooling to 100 DEG C, and taking out the sludge powder. According to the sewage purification method for reducing emission of the greenhouse gas discharged by the constructed wetland, the impurity removing, drying and grinding device is arranged, so that full-automatic preparation of sludge powder can be realized, the labor investment is reduced, the quality of the ground sludge powder can be greatly ensured, workers can conveniently carry out next treatment on the pulverized sludge, and the workin |
