Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sludge treatment, and in particular to a sludge treatment system and device for ecological restoration. BACKGROUND

[0002] Although there are some automatic sorting equipment on the market at present, most of them are for conventional materials, and lack effective intelligent recognition and sorting ability for sludge which is complex in composition and various in nature. The sludge contains various pollutants such as heavy metals and organic pollutants, and the physical and chemical properties of the pollutants are quite different. The existing equipment is difficult to accurately identify these characteristics and carry out precise sorting. Moreover, although the existing ecological restoration technology attempts to restore the soil ecology, it often fails to achieve the desired results due to the lack of accurate classification and treatment of sludge. The traditional treatment method cannot effectively recycle and utilize these resources.

[0003] Chinese Patent Publication No. CN110788130A discloses an ecological restoration method for copper mine area contaminated soil. The method includes removing large floating stones on the surface of the contaminated mine area soil, turning and crushing the soil to be restored, and airing it for 2-3 times. An appropriate amount of municipal sludge is added to the aired mine area soil, and after 20-30 days of stabilization, the soil is turned again and drainage ditches and water collection pools are designed. Duckweed seeds or duckweed seedlings are sown on the stabilized and turned mine area soil to achieve vegetation restoration. However, this method only aims at the ecological restoration of copper mine area contaminated soil, and it is difficult to intelligently process the sludge, thus it is difficult to improve the processing efficiency, accuracy and safety of the whole sludge treatment process.
