Description
Technical field
The present invention relates to sludge aerobic fermentation technical field more particularly to a kind of multilayer sludge aerobic installation for fermenting and sides
Method.
Background technology
With the quickening of Urbanization in China, sludge yield increasingly improves, a series of so as to be brought by Treatment of Sludge
Problem is increasingly urgent.In municipal sewage and During Industrial Wastewater Treatment Process, the sludge quantity of generation account for about always handle 0.3%~
0.5% (in terms of moisture content 97%), sludge components are complicated, containing sex pheromone, parasitic ovum, poisonous and hazardous heavy metal and
A large amount of hard-degraded substance, such as deals with improperly, easily causes secondary pollution to environment.But also comprising many abundant in sludge
Nutriment (such as nitrogen, phosphorus, potassium), these nutriments pass through proper treatment, can improve soil.Although China has introduced a batch
Advanced sludge treatment device, while the technology of Treatment of Sludge is there has also been larger development, but due to Treatment of Sludge system of China
System also has larger gap in complete set level with developed country, so there are still equipment is backward, management level is poor, safeguards
The problems such as horizontal relatively low, efficiency is low, less economical.
City sludge contains a large amount of organic matters and content of beary metal is less, suitable for carrying out aerobic compost.Aerobic compost can make
Sludge stabilizing, and can also make the killings such as pathogen, the parasitic ovum in sludge, final product in hot fermentation
For fertilizer and the modifying agent of soil.But in sludge composting, since influence factor is more, it is generally unable to reach best heap fertilizer efficiency
Fruit；Simultaneously because composting cycle usually requires 15~20 days, land seizure area is larger；Ventilation effect is poor in composting process,
Cause to ferment uneven, effect is poor, and fermentation time is long；The odor pollutions such as ammonia, volatile organic matter are difficult in composting process simultaneously

Outside, since the arrangement number of plies is more, every layer all needs arrangement turning machine, while every block of supporting plate need to be overturn, and device overall structure is answered
It is miscellaneous, it is susceptible to failure.Moisture percentage in sewage sludge is high, and fermentation time is long, needs big volume fermentation cabin, while need a large amount of ancillary equipments
Sludge roll-over etc. is carried out, land seizure amount is big.In sludge aerobic fermentation process, foul smell generates inevitable, existing sludge fermentation
Technology ozone Control is difficult, be easy to cause secondary pollution.Sludge aerobic fermentation heap body is higher, and it is uneven to be easy to cause the fermentation of heap body
It is even, and due to the compaction of heap body, ventilation effect is poor, causes fermentation time long, ferment effect is poor.
