Background technology
Since 21 century, as economy develops rapidly, the annual production of China's sewage sludge sharply increases, wherein 2014
Nearly 40,000,000 tons of yield.Early in nineteen ninety-five, World Water environmental organization determines to use the general of " biosolids " substitution " sewage sludge "
Read[7], its specific definition is:" a kind of pollutant being rich in using organic matter ", highlighting sewage sludge has what is recycled
Value so that recycling sludge, the concept of energy are widely accepted.
Due to the moisture content of sludge is high, energy density is low etc. factor reduces its using only economy, can not yet obtain
To effective exploitation and reasonable utilization.The moisture content of sludge is typically larger than 70%, and containing combustible components such as a large amount of C, H, if can be right
Energy therein is reclaimed, and for supplying or as fuel oil substitute, all there is weight for solving environment and energy problem
Big meaning.
Because the viscosity of sludge is larger, moisture content is higher, it is relatively difficult that pyrolysis is directly carried out to it;By sludge and life
Material wood chip is blended, and can reduce the viscosity of raw material and total moisture content, increases carbon content in raw material, then can effectively solve
This problem.However, the blending difficulty of sludge and wood chip is larger, sludge and biomass wood chip blending technique, blending are had no at present
Device and blending systematic account.
