Change system.
Background technology
Along with the fast development of China's urban wastewater treatment cause, sewage treatment plant's quantity is on the increase, mud generation amount
The most day by day increase.China's urban wastewater treatment firm quantity reaches more than 4000 at present, and mud year generation amount is (aqueous at 40,000,000 tons
Rate 80%) more than.Mud not only moisture content is high, volume is the hugest, and containing a large amount of hardly degraded organic substances, heavy metal and
Pathogenic microorganism and parasitic ovum etc., as processed without effective, easily cause secondary pollution, affect environmental improvement effect.
At present the Treatment of Sludge of China to concentrate, dehydration, but the moisture percentage in sewage sludge after concentrated dehydration be still up to 70% ~
80%, therefore, dewatered sludge is carried out drying and other treatment, be the key realizing recycling sludge treatment and use.
The sludge drying process of modernization is mainly heat drying, uses intensive mud drying device, passes through external heat
Moisture in mud is evaporated by source, thus reduces moisture percentage in sewage sludge.Energy consumption and the operating cost of sludge heat drying are higher, run pipe
Reason difficulty is relatively big, and drying equipment is harsh to service requirement, and it is improper to run, and there is the security risk of blast.The sludge drying of China
Technology is still in the starting stage, although built more than ten seat sludge heat drying projects, but the technology of Introduced From Abroad and setting mostly
Standby, and mostly use general exsiccator, apparatus adaptability can be undesirable, and system energy consumption is the highest, and operating cost remains high,
It is difficult to maintain stable operation.The sludge aerobic fermentation technique of China is the most necessarily applied, but there is fermentation time length, minimizing
The shortcomings such as DeGrain, floor space are big.

The organic produced biological heat energy of degraded during aerobic fermentation, it is achieved the fast dewatering mummification of material and volume reduction decrement.Raw
Thing mummification is for the purpose of quickly reducing the moisture content in mud, but does not has external energy, and there is shortening in the most biological dewatered cycle
Space, and utilizing this clean energy resource of solar energy is a kind of feasible mode for external energy.
Mud solar energy desiccation mainly makes mud internal moisture accelerate outwards evaporation by solar radiation effect, then leads to
Cross Natural Circulation or the moisture of Sludge Surface is taken away by ventilation.Mud solar energy desiccation compared with traditional heat drying technology, energy
Consume little, operational and administrative expenses is low, the power consumption evaporating 1 t water is only the 1/30 of conventional thermal drying technique.While it is true, solar energy
The energy utilization efficiency of desiccation apparatus is relatively low, needs the longer time of staying and bigger floor space, it is therefore desirable at sewage
There is space, the most available place in treatment plant.And solar energy desiccation treatment effect is by weather and seasonal constraint, very
Be hard to keep uniformly, continuous print run, for these many solar energy desiccation techniques take thermal-arrest or with other auxiliary thermal source connected applications,
But which increase process costs.And even so, the engineer applied result in Germany shows that whole winter, mud was required for stopping
Staying in mummification workshop, this increases the floor space requirements of solar energy desiccation apparatus further.
Therefore, the restriction existed for above-mentioned technology, develop a kind of efficient sludge deep drying and other treatment technique with
System, for promoting recycling sludge treatment and use, lifting specific resistance to filtration industry level significant.
