The integrated collaborative treatment system based on multi-source waste according to claim 1 is characterized in that: The mixing unit comprises an agitator (8) and a mixing bin (9), wherein the agitator (8) is used to mix domestic waste, medical waste and sludge carbon to form a multi-source waste mixture, and to convey the multi-source waste mixture to the mixing bin (9), and the mixing bin (9) conveys the multi-source waste mixture to the incineration unit via a fifth conveyor.

7. The integrated collaborative treatment system based on multi-source waste according to claim 5 is characterized in that: The incineration unit comprises an incinerator (10) and a waste heat boiler (11), wherein the incinerator (10) and the waste heat boiler (11) are connected, and the waste heat boiler (11) is used to perform heat exchange on the high-temperature gas generated by the incinerator (10), and the flue gas outlet (12) of the waste heat boiler (11) is connected to a chlorobenzene sampler (4).

8. The integrated collaborative treatment system based on multi-source waste according to claim 7 is characterized in that: The control unit signal is connected to the chlorobenzene analyzer (5), the incinerator (10), the third conveyor and the fourth conveyor. The control unit signal is used to receive the chlorobenzene concentration signal of the chlorobenzene analyzer (5), control the temperature of the incineration unit after comparing the concentration with the emission standard, and control the conveying rate and ratio relationship of the third conveyor and the fourth conveyor to adjust the chlorobenzene concentration generated by the incineration unit to achieve the emission of dioxins meeting the standard.

9. A method for high-temperature coordinated incineration of multi-source waste, characterized in that: The incineration treatment is carried out using the integrated coordinated treatment system according to any one of claims 1 to 8, comprising the following steps: The sludge is added to the sludge co-treatment unit, where it is dried by an electric heating furnace, converted into sludge charcoal, and produces pyrolysis gas; The sludge carbon is transported to the mixing unit as a fuel auxiliary through the sludge co-treatment unit, while the domestic waste treatment unit and the medical waste treatment unit respectively transport the domestic waste and the medical waste to the mixing unit; The mixing unit mixes domestic waste, medical waste and sludge carbon to form a multi-source waste mixture, and collects and transports the multi-source waste mixture to the incineration unit; The pyrolysis gas is transported to the incineration unit through a conveying pipeline. The incineration unit incinerates the multi-source waste mixture transported by the mixing unit, and recycles the waste heat of the flue gas generated by the incineration. The detection unit monitors the chlorobenzene concentration of the flue gas generated by the incineration unit in real time, and transmits the chlorobenzene concentration signal to the control unit. The control unit adjusts and optimizes the combustion process of the incineration unit in real time after comparative analysis based on the feedback signal, and controls the delivery rate and ratio of the domestic waste treatment unit and the medical waste treatment unit, so that the dioxin content in the flue gas generated by the incineration unit meets the environmental protection performance standards.
