The incineration of sludge disposal methods need to sludge drying after incineration can be carried out, different processes, to achieve the effect is different, the advantages and disadvantages are also different, today Sanyuan will come and we briefly.

1. direct landfill after steam drying

The utility model has the advantages that the equipment is simple, and the operation cost is low.

Disadvantages: using steam drying, sludge in water evaporation and evaporation together, and hazardous substances after sludge has not been damaged, only the reduction cannot be harmless, gas and dry sludge generated on environmental emissions still cause pollution to the environment. Can not meet environmental requirements.

2. steam drying reduces water content and then burns

The utility model has the advantages of small equipment load and low running cost.

Disadvantages: sludge drying gas produced two pollution to the environment, can not meet the environmental requirements.

3. sludge was dewatered to 80% after incineration

Advantages: achieve standard discharge

Disadvantages: higher operating costs, less economic.

In addition, the alkali residue is treated by incineration, which can be treated thoroughly without causing two pollution or other effects. But the calorific value is low and the cost of single burning is high.
