High-temperature aerobic fermentation sludge compost treatment and disposal system

Abstract

The invention belongs to the field of harmless treatment and recycling technologies for organic solid waste resources, and particularly relates to a high-temperature aerobic fermentation sludge compost treatment and disposal system which comprises a sludge pretreatment system and a sludge compost fermentation process control system. The sludge pretreatment system is used for conveying and mixing sludge and carrying out high-temperature aerobic fermentation on the sludge, and the sludge compost fermentation process control system is used for acquiring high-temperature aerobic fermentation process parameters of the sludge in an online manner and carrying out turning and aeration treatment on high-temperature aerobic fermentation sludge according to the process parameters, so that fermentation processes can be controlled. The high-temperature aerobic fermentation sludge compost treatment and disposal system has the advantages that high-temperature aerobic sludge compost processes are controlled, accordingly, materials can be adjusted to be in the optimal fermentation states, organic matters in the sludge can be decomposed under the effects of beneficial flora, energy can be released, effects of killing harmful pathogenic bacteria can be realized, agricultural standards on the contents of effective components in final products and microbiological indicators can be ultimately met, and the sludge can be ultimately reduced, harmless and recycled.

Description

technical field [0001] The invention belongs to the technical field of harmless treatment and resource utilization of organic solid waste resources, and particularly relates to a sludge high-temperature aerobic fermentation composting treatment and disposal system. Background technique [0002] A large amount of untreated sludge is stacked and discharged arbitrarily, which will not only waste the useful nutrients in the sludge, but also cause new pollution to the environment. Therefore, how to scientifically treat the sludge with large output and complex composition to reduce, harmless, recycle and stabilize it has become one of the common concerns of environmental circles in my country and even the whole world. Agricultural sludge has low investment, low energy consumption, and low operating costs, and some of it can be converted into components of soil amendments. Therefore, agricultural sludge is considered to be a potential disposal method. However, the sludge compositi...

AI Technical Summary

Problems solved by technology

However, the composition of sludge is very complex, not only rich in organic matter and nutrients such as trace elements necessary for plant growth, but also contains a large number of pathogenic bacteria, parasites (eggs), heavy metals such as copper, zinc, chromium, mercury, salts and Refractory toxic and harmful substances such as polychlorinated biphenyls, dioxins, and radionuclides will have great risks if they are directly used in agriculture. The sludge must be thoroughly treated and disposed of in a harmless manner before it can be used in agriculture. Therefore, there is an urgent need A new type of scientific sludge aerobic composting treatment and disposal system, in order to provide a technical model for the rational and effective utilization of regional sludge and establish an effective way for urban sludge disposal and utilization
