Increase, while the yield of sludge is also being increased rapidly.Sludge is as the resource being misplaced, if not obtaining good place
Reason, can bring serious secondary pollution to environment.With the continuous deterioration of environment, the growing tension of land used and people's environmental consciousness
Enhancing, sludge is effectively treated and gradually brought into schedule.
Sludge is the product after sewage disposal, includes the compositions such as debris, bacterial clump and inorganic particle.Sludge
Water content is high, is a kind of thick medium between solid and liquid, it is difficult to reach solid-liquid point by simple gravitational settling
From purpose.In numerous sludge treatment techniques, anaerobic digestion is at present in the world using dirt that is relatively broad and working well
Mud stabilizes the handling process with recycling, the weight and volume of sludge can not only be reduced by this technique, moreover it is possible to natural pond
The form of gas reclaims the biological energy source in sludge, and the country advocates this sludge treatment technique always in the last few years.But due in sludge
Organic matter largely be cellular material, cellular material is tightly wrapped up by cell membrane or cell membrane, positioned at intracellular macromolecular
Material can not be released, it is impossible to which the content for carrying out organic matter in anaerobic digestion, and sludge with anaerobic bacteria is limited, finally leads
Cause the inefficient of anaerobic digestion.Therefore cell thing in organic matter is made, it is necessary to pre-processed to sludge before anaerobic digestion
The cell wall rupture of matter, that is, hydrolyze.
Because the thermal capacitance of sludge in itself is big, and the features such as gapless, poor fluidity, cause thermal conductivity also poor, in sludge water
Solve in heating process, existing sludge hydrolytic equipment is insufficient due to stirring so that sludge flowing is small, causes heat transfer not filled
Point, it is uneven, ultimately result in hydrolysis efficiency low..
