Description
Technical field
The present invention relates to technical field of sludge treatment, more particularly, to a kind of sludge fermentation device.
Background technique
With the raising of Chinese society expanding economy and the level of urbanization, urban wastewater discharge constantly increases, sewage
Handling rate improve year by year, and sludge is the discarded object of power boiler discharge during municipal sewage treatment, organic matter, battalion in sludge
It supports substance and other polluters substantially passes through microorganism either physics, chemical action and have been transferred in sludge.According to estimating
Calculate 2015 China's sludge yield (80% moisture content) more than 60,000,000 tons.The complicated component of sludge is one kind by a variety of micro- lifes
The organic matter of zoogloea and its absorption that object is formed, the polymer of inorganic matter composition also contain in distress in addition to containing a large amount of moisture
Organic matter, heavy metal, salt and the pathogenic microorganism of degradation and parasitic ovum etc..The nutrition such as organic matter and nitrogen, phosphorus in sludge
Constituent content is higher, if will will cause great environmental pollution into water body environment, while being also a kind of great resource wave
Take.
If excess sludge is mishandling, it will cause immeasurable serious consequence to ambient enviroment.Sludge is safe and effective
Processing disposition, be the inevitable requirement of China's sustainable development.Different from anaerobic digestion, sludge aerobic fermentation has fermentation period
Short, operation cost is low, and foul gas discharges few advantage, and land use becomes China's municipal sludge after sludge high temperature aerobic fermentation
One of main processing disposal options.
Existing sludge treatment device is limited by sludge weight, and the fermenting case for being currently used for sludge aerobic fermentation is tied
The restriction of structure intensity has that small volume or occupied area are larger, is not easy to carry out fairly large Treatment of Sludge.This
Outside, for the industry also in developing stage, the degree of automation is lower, lacks large-scale automated processing equipment.Therefore, Yi Zhongneng
The equipment for improving efficiency of sludge treatment, becomes the demand of industry.
Summary of the invention
It is an object of the invention to overcome at least one defect of the prior art, a kind of sludge fermentation device is provided, can be had
Effect ferments to a large amount of sludge.
In order to solve the above technical problems, the technical solution adopted by the present invention is that:
A kind of sludge fermentation device is provided, including fermenting case, the aerating system for being aerated to sludge and for putting
