Description
Technical field
The present invention relates to sludge treatment field, and in particular to a kind of mechanical dehydration coupling desiccation pyrolysis prepares the side of sludge carbon
Method.
Background technology
With the fast development of Chinese society economy and Development of China's Urbanization, the scale of municipal sewage plant constantly expands,
Sludge yield also increases considerably.The disposal options of sludge are mainly with aerobic compost, landfill, burning etc. at present.
Sludge aerobic compost can utilize sludge in organic principle, but due to Heavy Metals in Sludge in composting process not
It can cure, have the risk that can be discharged into environment, the Ministry of Agriculture forbids sludge manure to enter farmland, while needs to add in aerobic process
A large amount of base-material, is not reduced not only, but also causes increment, therefore there are risks for this method.
Sludge incineration technology can realize the thorough minimizing of sludge, and there are two types of modes at present, and a kind of is 80% moisture content
Sludge directly burns, and this method sludge calorific value is zero or negative value, and very big, 5% of mixed-fuel burning proportion no more than fuel is impacted to boiler,
Treating capacity is limited.Another kind is burned after sludge drying, and which is solved to boiler combustion shock problem.But the mode burned
Bioxin is easily generated, and when sludge mixes burning in existing boiler can generate bioxin, station boiler almost all is not provided with
The treatment facility of bioxin, You dioxin emission risks.
