[0002] With the development of industry and the rise of the construction industry, a lot of waste will appear in the production process of building materials and decoration materials, especially hazardous waste. If the waste is not centrally treated and scattered outside, it is easy to cause danger to the staff. Therefore, a comprehensive treatment device for hazardous waste is needed to treat the waste in time.

[0003] At present, most of the existing waste treatment devices use incineration to treat hazardous waste. During the incineration process, the waste will produce a large amount of harmful gases. Traditional treatment devices only perform simple filtering treatment on the flue gas, resulting in a certain amount of harmful substances in the flue gas being discharged into the air, causing pollution. For this reason, we propose a comprehensive hazardous waste treatment device. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1.

Finally, it is introduced into the sedimentation tank for sedimentation, so that it can be precipitated inside it, and the impurities that are not removed are precipitated inside the sedimentation tank, thereby achieving the purpose of deep filtration, and it can also dissolve the water-soluble harmful gases in water to reduce the pollution of the smoke.

[0014] 2.
