The mud of 150cm, sprays mycopowder a liquid 150-300ml, adds adjuvant a solution 100ml；Then repave the mud into 80-155cm,
Finally spray mycopowder b liquid 400-500ml, after room temperature culture 12-24h, take out and obtain mud former ferment thing；
Step 4, former for gained mud ferment thing is divided into 16 parts, after wherein eight parts are respectively added in 8 sludge sumps, at 8
Sludge sump middle berth enters the mud of 1.2-1.5m, then sprays mycopowder c liquid 1-2l while stirring, is stirred for adding adjuvant b mixture
25-30kg, finally repaves the mud into 1.3-1.6m, after mycopowder c liquid 1-2l is sprayed in stirring, is stirred for adding adjuvant b mixture
30-40kg；Covered plastic film, normal temperature fermentation 4-6d, mud after being fermented；
Step 5, will ferment after mud after mud tiling rotary tillage dry in the sun 3 days after fermentation, the moisture content in mud drops to 18%-
20%；Held together into raft with loader, be ground into graininess, that is, process and complete, the mud after being processed.
2. employing microbial bacterial agent as claimed in claim 1 process sewage plant sludge method it is characterised in that: described microorganism
In microbial inoculum, the viable bacteria content of each bacterium is in 300-1000 hundred million/g.
3. employing microbial bacterial agent as claimed in claim 1 process sewage plant sludge method it is characterised in that: described mycopowder a,
Mycopowder b or mycopowder c is vacuum lyophilization mycopowder.
