One or more of salt, sodium Diacetate, calcium propionate, sodium lactate.
The utility model has the following beneficial effects:
1, the formula of general Sludge deodorant is more complicated, including bentonite, straw powder, ferrous sulfate, calcium oxide powder, secondary
Chlorate etc., the medicament for mainly playing bactericidal effect is hypochlorite, and bactericidal agent containing chlorine has good sterilization effect, but dirty
Mud property is different, and the dosage of the bactericidal agent containing chlorine is different.The utility model is added by total residual chlorine norm controlling bactericidal agent containing chlorine
Dose while to guarantee sterilization effect, guarantees that return water will not impact the biochemical system of sewage plant.
2, the content of organic matter is high in waterworks sludge, and after sterilized dose of inactivation, microbial cell is dead, but the content of organic matter
Still very high, nutrient is abundant, also, after sludge dewatering moisture content still between 60% ~ 85%, exposure in air or with it is outer
It is very easily corrupt again during boundary contacts, generate foul smell.The utility model uses two-stage sterilizing methods, mud after dewatering
Cake outer layer sprays preservative, it is ensured that sludge no longer generates foul smell in transport and subsequent disposition.
3, the utility model deodoration system is easy to operate, and equipment volume is small, can carry out deodorization in situ to sludge in sewage plant
Processing.
