Spill in 60-95 parts of steps（1）On the culture mud of gained, it is thoroughly mixed uniformly, obtains the primary containing particular organisms bacterium dirty
Mud.
Step 3：Biological bacteria expands numerous.
By step（2）The preliminary sludge of middle gained banks up fermentation in fermentation tank, after fermentation temperature rises to steadily, enters
Row roller is overturned, and continues to bank up fermentation, after temperature rises to steadily again, obtains biological sludge finished product, fermentation time typically exists
12-48 hours.
Step 4：Discharge, dry.
Biological sludge is spread, stirred, is dried, airing.
Step 5：Packaging, storage.
Dried biological sludge, is packed by quantitative use laminating adhesive woven bag, is stored in health, shady and cool, dry, ventilation
Place.
Preferably, the step（1）In sludge refer in particular to municipal sewage plant discharge sludge, do not contain a huge sum of money
Category, total phosphorus content, total nitrogen content, 550 degree and 900 degree of burning decrements are determined and met the requirements.
Preferably, the step（1）In sterilization refer to utilize ultraviolet radioactive method, by sludge, rice bran, wheat bran,
The materials such as careless carbon, sterilize 2-4 hours, sterilization rate reaches 99% under ultraviolet lighting.
Preferably, the step（1）In the nutritional agents biological bacteria breeding needed for nutriment.
