In general, after the activated sludge is identified by harmful substances, physical landfill is preferred, and with the development of urbanization, landfill plants are generally saturated, so that the landfill requirement is higher and higher, and the sludge landfill is limited; the single high-temperature incineration is not economical, the secondary pollution risk of dioxin also exists, the high-temperature combined incineration needs a cooperative unit, the harmless treatment cost is high, and the popularization is difficult; the low-temperature drying technology is carried out by a heat exchange principle, so that the occupied area is large, the treatment time is long, and the economy is not good; the lime dry treatment is limited by the production of lime raw materials, increases the sludge amount and increases the post-treatment cost. After the sludge utilization is divided into high-temperature fermentation, low-temperature fermentation and low-temperature drying, composting is recycled; or incinerated to be used as building material auxiliary materials and the like. The compost recycling risk is higher and is not beneficial to popularization under the influence of heavy metal, dangerous organic matters and the like; the use of the said additive as building material can reduce the overall performance and is not favorable to popularization.

Has no harmless treatment capability on organic matters, heavy metals and the like.
The plasma material treatment has the defects of low pretreatment efficiency, high plasma energy consumption, unstable performance and high control requirement on the water content. The pure plasma treatment has high energy consumption of equipment, serious sensible heat waste and limited energy consumption utilization level of heat energy recovery efficiency; the high-temperature plasma treatment needs to add an auxiliary carbon source, and the low-temperature plasma technology has poor solid-liquid separation effect.
