Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Its moisture content of the sludge conditioning of sewage plant>93%, into peroxide aeration tank, peroxide aeration tank is furnished with agitating device, bottom
Portion is provided with aerator, and because sludge solid content is higher, simplex aeration is not enough to stir by mud granule, and sludge can occur
Settle, oxygen content skewness in sludge solutions, and easily cause aeration hole plug, aeration is carried out simultaneously with stirring, is also avoided
The generation of local anaerobic.Oxygen content is heightened to the mg/L of 3 mg/L ~ 5, carries out peroxide aeration, excessive oxygen suppresses bacterium glue
The growth of group, quickly breeding causes activated sludge skeleton structure to destroy to der Pilz, sludge decomposition.Control filamentary discharges to 1.2 ~
1.5 times, suppress der Pilz excessively foam and scum silica frost caused by breeding by the sterilizing sludge solutions that flow back.Der Pilz in activated sludge
With active zoogloea symbiosis, to keep the purification efficiency of the flocculation structure of sludge and biochemical treatment, der Pilz is caused quickly to breed
Method have a lot, it is considered that, because der Pilz has larger specific surface area and relatively low oxygen saturation constant, low DO can draw
The quick breeding of der Pilz is played, but low DO can also produce foul smell, pollute surrounding environment；Inorganic salts are added, or heightens, turn down dirt
Mud pH value of solution can cause der Pilz amount reproduction, but acid adding or add alkali to cause pH to change, and finally also need plus alkali or acid adding are by pH
Neutrality is recalled to, not only increases medicament expense and uses, also add soluble ion concentration in water body, be unfavorable for the final discharge of water body.
Sludge after disintegration enters bactericidal unit, and bactericidal unit is obturator, and top is provided with negative-pressure ward cover, will sterilized
During caused a small amount of foul smell be discharged into by negative-pressure ward in aerobic aeration pond；Bactericidal agent is provided with inside bactericidal unit to spray

Agent is NaC1O, NaC1O2Or Cl2In one kind, the chemical feeding quantity of bactericidal agent is chloride ion content 35mg/L ~ 50mg/L.
Sludge after sterilizing enters the reaction tank of hydrolysis acidification pool, and larger molecular organicses are decomposed into small by hydrolysis acidification reaction
Solution overflow after molecular organic enters mixing pit, the reacted sludge of hydrolysis acidification by pumping into mixing pit, sludge
Enter aerobic aeration pond as carbon source after being mixed with the aqueous solution, due to containing a small amount of bactericidal agent, shadow in the sludge solutions after sterilizing
The normal growth of microorganism in aerobic aeration pond is rung, microorganism is maintained by supplementing the activated sludge in a certain amount of sludge storage pool
Normal survival volume, it is 4.7 ~ 9.5 into the sludge quantity in peroxide aeration tank and the sludge quantity ratio for being directly entered aerobic aeration pond:1,
It is the mg/L of 2 mg/L ~ 3 to control in aerobic aeration tank dissolved oxygen concentration, and the residence time is 3 ~ 5 days.
Mud decrement after aerobic aeration reaches more than 60%, because microorganism largely consumes in sludge, is filled into sedimentation
Put, by sedimentation, supernatant is discharged into the water inlet of sewage treatment plant again, and the sludge of precipitation is further removed into odor removal
It is smelly；Sludge after deodorization is dehydrated, and the sludge after dehydration enters desiccation apparatus, and aerobic aeration pond is by water resource heat pump to desiccation
Device provides thermal source, and the caused dewatered sludge that is destitute of smell is obtained after desiccation.
