Abstract

The invention relates to a high-efficiency full-closed sludge treatment system and a method thereof. On one hand, the high-efficiency full-closed sludge treatment system comprises a sludge bin, a quicklime powder bin, a stirrer, a spiral conveyor, a digestion bin, a powdery organic storage bin, a pelletizer and a finished product bin; a mixture formed by stirring sludge in the sludge bin and quicklime in the quicklime powder bin with the stirrer is transported to the digestion bin through the spiral conveyor; the mixture in the digestion bin and the powdery organic matter in the powdery organic storage bin are stirred by the stirrer, pelletized by the pelletizer, and transported to the finished product bin by the spiral conveyor; on the other hand, the invention also provides a method forimplementing the high-efficiency full-closed sludge treatment system. The method has the advantages of simple treatment process, high efficiency, full closeness, no need of composting, small fixed investment, little occupied area, low treatment cost, thorough deodorization, no secondary pollution, cyclic utilization of the treated material and the like; and the high-efficiency full-closed sludge treatment system realizes the minimization, stabilization, harmlessness and recycling of the sludge.

Description

technical field [0001] The invention relates to a sludge treatment system, in particular to a highly efficient and fully enclosed sludge treatment system and a method thereof. Background technique [0002] The current sludge, especially the sludge produced by urban sewage treatment plants, is usually disposed of by landfill, incineration, offshore dumping, fertilizer making, and brick firing in China. For example, the only sludge treatment plant in Guangzhou is to dry the sludge and mix it with clay and then burn it into red bricks. This is currently the largest sludge treatment BOT project in the world. [0003] At present, the traditional technology is not effective in treating sludge. Therefore, how to solve the sludge treatment, especially the sludge of the sewage treatment plant is an urgent problem to be solved. At present, there is no comprehensive treatment system and method with simple treatment process, less fixed investment, less land occupation, low treatment c...
