For example: part of sludge in countries such as Europe and America is used as farmland fertilizer, if the sludge is used as fertilizer throughout the year, heavy metal ions can be accumulated in soil, so that the heavy metal in the soil exceeds the standard, crops absorb the heavy metal ions, and the food safety is endangered.

Also, the sludge incineration process inevitably produces a large amount of pollutants, such as fine dust particles, acid gases, heavy metals, dioxin, and the like.

For years, in island countries in Japan, the incineration process has been preferred as a process for treating sludge, and the incineration cost is more than 500 yuan per ton of sludge with water content of 80% accounting for 66.9% of the total amount of sludge. Annual sludge production in Japan is about 896 million tons (water content is 80%), and the treatment cost is 450.4 hundred million yen (about 27.52 hundred million yuan RMB). The defects of the incineration process bring huge resource waste.
