Heap is primary, and fermentation discharges after 30-45 days.
Preferably, excess sludge progress compost needs to carry out engineering processing in the step S2, the specific steps are that:
A, PADS is put into excess sludge, is uniformly mixed, and continues to put into smashed sticky loess and modified attapulgite, ammonia
Nitrogen clears up bacteria preparation and mud decrement bacteria preparation and sawdust, stirs evenly, mixing speed 150-200rpm is then allowed to stand 3-
4 days, so that microbiologic population is carried out oxygenolysis to the gas chromatography in excess sludge in wet condition and be converted into class corruption
Grow matter；
B, compost treatment is carried out using static forced ventilation mode, mud mixture reaches decomposed after 28-32 days, obtains dirt
Mud composting production, by the excess sludge quality of compost is loose, cation exchange capacity (CEC) dramatically increases, bulk density is reduced, can be by plant
The nutritional ingredient utilized increases, pathogen and parasitic ovum almost all are killed.
Compared with prior art, the beneficial effects of the present invention are: a kind of combined type stony desertification ecology provided by the invention is repaired
Compound method, compared with traditional technology, this method is fairly simple, carries out heap using sewage treatment excess sludge in Rocky Desertification Control
Fertilizer and in Rocky Desertification Control composting process use zeolite powder, loose, the cationic exchange by the excess sludge quality of compost
Amount dramatically increases, bulk density is reduced, pathogen and parasitic ovum almost all are killed, and can be increased by the nutritional ingredient that plant utilizes
Add, improves vegetation survival rate；Zeolite powder rough surface and the porous structure having, zeolite powder is acidproof, bulk density 1.2-1.4kg/
It rises, without grease and crude fibre again without electrostatic phenomenon, makes it have stronger carrying capability, heavy metal can be made equably to be adsorbed on
Its surface, while the release time of microcomponent in compost can be appropriately extended, it is more advantageous to plant absorption, the addition of zeolite powder mentions
The passivation effect and composting efficiency of high heavy metal.
