The dephosphorization of high temperature mud Jing guanites dephosphorization system 7 and part ammonia nitrogen after pyrolysis, Jing coolers 8 are cooled to normal pressure,
It is back to after Sewage Plant water inlet, and municipal sewage mixing and enters sewage disposal system 3.
The deodoration system 12 processes the low concentration foul smell that sewage disposal system 3 and Dehydrator for Slurry 4 are produced, while processing dirty
The high concentration foul smell out of mud preheating pulp tank 5.
The utility model discloses a kind of method that municipal sewage and sludge cooperate with circular treatment, comprises the steps：
The first step：Through the process of grid, setting pot and sewage disposal system, sewage becomes qualified discharge to municipal sewage
Water and sludge；
Second step：Sludge is preheated through pulp, enters into and mud organic substance pyrohydrolysiss are completed in sludge hot hydrolytic reaction pot
Reaction, in pyrohydrolysiss course of reaction, the larger molecular organicses in sludge are pyrolyzed into small molecule and easily biochemistry Organic substance, specifically such as
Under：Sludge protein hydrolysis of organic matter is hydrolyzed into Fructose and Fructus Vitis viniferae into polypeptide and aminoacid, sludge cell wall fiber type organic
Sugar, sludge fats hydrolysis of organic matter is into fatty acid and triglyceride etc.；
3rd step：High temperature mud Jing guanite dephosphorization process dephosphorization and part ammonia nitrogen after pyrolysis, Jing coolers are cooled to
Normal pressure, is back to after Sewage Plant water inlet, and municipal sewage mixing and enters sewage disposal system, and place of moving in circles is cooperateed with successively
Reason.
In the second step, the sludge of generation enters into sludge hot hydrolysis after the process of pulp preheating can 5
The reaction of mud organic substance pyrohydrolysiss is completed in kettle 6, in pyrohydrolysiss course of reaction, the larger molecular organicses in sludge are pyrolyzed into little
Molecule and easily biochemistry Organic substance, the temperature after sludge pulp preheating：55 DEG C -80 DEG C, sludge enters sludge hot hydrolytic reaction pot, note
Enter superheated steam, final pyrolysis mud temperature is heated to：140 DEG C -170 DEG C, when sludge is stopped in sludge hot hydrolytic reaction pot
Between 13 minutes to 20 minutes, whole process is a continuous technical process.
In the second step, sludge reacts through sludge hot hydrolytic reaction pot 6, becomes liquid state mud, solubility
COD has accounted for 95%, BOD/COD >=0.6.
