The preparation method of artificial landfill cover materials comprises the steps of: mixing 100 wt% of sewage sludge and 5-30 wt% of quicklime for solidifying the sewage sludge; adding a porous deodorant at an amount of 10-50% by weight of 100% of the sewage sludge; and adding a mixture of waste plaster and waste silica mixed at a ratio of 1:0.7 to the sewage sludge solid at an amount of 10-30% by weight of 100% of the sewage sludge. The deodorant is used to remove ammonia gas generated during use of the quicklime.</p> |
