Description
Technical field
The present invention relates to a kind of organic waste composting treatment method, belong to technical field of garbage disposal.
Background technology
As the horizontal quickening of Chinese Urbanization and the continuous improvement for the treatment of rate of domestic sewage, caused organic waste are also got over
Come more, a main part shows that sludge quantity sharply increases caused by sewage disposal process in organic waste.However, due to lacking
Weary rationally effective management method and processing disposal technology, a large amount of municipal sludges can only be stacked temporarily, thus caused secondary dirt
Contaminate and huge harm is brought to environment, seek rational processing treatment approach and asked as countries in the world letter focus to be solved
Topic.
Aerobic fermentation refers to utilize aerobic bacteria and oxygen, sludge high temperature is fermented, and it is processing and disposal municipal sludge
A kind of cost-effective good method, have the advantages that to make organic nuisance complete decomposition, control well.It uses multidisciplinary skill
Art, multiphase organic matter is decomposed in specific environment using microbiologic population, the humus by improving sludge into stabilization,
Often it is divided into three phases for infertile field or soil improvement, Composting Process：First stage is middle thermophase, and second stage is high temperature
Stage, phase III are the decomposed stages.The mark that middle thermophase terminates is heap temperature rise to 45 DEG C, hot stage OUR is high,
Temperature is high, volatile organic matter degradation rate is high, stink is dense；Then temperature was low, OUR is low the decomposed stage, voidage increases
Greatly, humus increases and stabilized.Aerobic compost is innoxious will to ensure that stack layers temperature is maintained above 5-7 days at 55 DEG C, to reach
The requirement of relation by marriage worm's ovum and Escherichia coli is killed, therefore whole processing procedure gets off to need altogether the time of ten days or so.
For the living environment that current house refuse is increasing, air and environmental quality requirement are strict, traditional place
The reason process cost time is longer, and treatment effeciency is relatively low, causes pending rubbish or solid waste pilling up time to grow, and heap
Caused stink is difficult to handle in fertile course of reaction, influences ecological environment, or processing needs to spend many resources, cost compared with
It is high.
