The present invention relates to a treatment apparatus and a treatment method of sewage sludge by pyrolysis, and more particularly, a shuttle kiln-type heat storage furnace and a kiln (rotary) dryer are connected to each other, and a microorganism deodorization tower is provided at a rear end thereof. Sewage sludge having a water content of 80% is put into a drier prepared by using a screw feeder and dried, and the dried sludge is stored in a storage container. At this time, pollutants such as odor generated are removed by the microbial deodorization tower, and the pyrolysis chamber of a simple cylindrical fixed structure connected to two units of four pyrolysis units in parallel and a high temperature heat storage furnace are connected to each other. After drying the dry sludge stored in the storage container into the pyrolysis vessel, it is loaded into the pyrolysis chamber using a hoist and thermally decomposed, and odors and decomposition gases (biomes: methane gas) generated at this time are circulated back to the combustion chamber of the high temperature heat storage furnace. The present invention relates to a sewage sludge treatment apparatus and a method for treating sewage sludge by pyrolysis that can effectively treat air pollutants.

In recent years, environmental pollution due to various wastes generated during industrialization is getting more serious, and various waste treatment technologies and pollution prevention technologies and policies have been proposed to cope with these problems as they become more real.

So far, sewage sludge has been treated in Korea by dumping, landfilling, and incineration, but since July 2003, direct landfilling has been banned. There is no treatment method, but due to the disposal costs due to incineration, it is still being dumped at sea. However, in case of dumping at sea, there is concern about damages caused by marine pollution.In case of incineration, most incinerators are incinerated together with the state of garbage.In this case, the exhaust gases after combustion reaction (HCl, HCN, NOx, Dioxin, etc.) After-treatment equipment is necessary because of air pollutants), and the burden of facility cost for post-treatment equipment is high, and the management cost by auxiliary fuel cost is very large. In addition, about 30% of residues are generated due to incomplete combustion, and the residues are reclaimed at landfill sites. However, in case of landfills, secondary environmental pollution which leads to landfill grounding or land and groundwater contamination by leachate has become a problem.

In addition, in the case of conventional incinerators, the capacity to be treated must be somewhat large, and since the initial equipment cost of the incinerator for the throughput is high, the treatment that can be incinerated compared to the amount of waste generated in each industry at present. In case of incineration of sewage sludge again, the incineration facilities in Korea should increase enormously. In this case, the problem of air pollution and the huge burden of investment and maintenance and maintenance costs due to incineration are very high. Seriously, there has been much research.
