Problems solved by technology

Although the disposal method for waste paint slag has achieved waste reduction, the incineration process is prone to secondary pollution, high heat energy consumption, large flue gas volume, and high unit treatment cost; while the disposal method for sludge Effective reduction has not been achieved, and a large amount of landfill volume is required. In the current environment of land shortage in big cities, it is obviously out of date

Embodiment 1

[0052] In Example 1, the solid waste treatment of Tianjin FAW Toyota is taken as an example.

[0053] The existing solid waste of Tianjin FAW Toyota Motor Co., Ltd. includes waste paint slag generated during the painting process and wastewater treatment sludge generated during the metal surface treatment process, all of which are hazardous waste. Both the waste paint slag and the sludge are stored in the silo. Since the organic components in the solid components of the waste paint slag account for more than 90%, the calorific value is very high, while the inorganic components in the solid components of the sludge account for about 50%. , lower calorific value.

[0054] Step 1: importing solid waste residue and sludge into different storage cavities in the waste storage bin;

[0055] Step 2: The daily processing capacity of the waste residue and sludge stored in the storage chamber is transported to the dryer at a ratio of 10:7 for mixing and shaping to form a mixture; in orde...
