Abstract

The invention discloses a method for curing sludge for landfill. The method includes: sequentially adding sodium carboxymethylcellulose I, fulvic acid, sodium carboxymethylcellulose, bacillus amyloliquefaciens, peptone, sodium carboxymethylcellulose III and lactobacillus acidophilus into the sludge, adding sepiolite powder into the sludge with stirring at last, spreading activated carbon on the surface of the sludge, standing for several hours, and filtering off liquid to finish treatment of the sludge. Adding time of the ingredients is specially restricted, treating time of every stage is strictly restricted, moisture content of the sludge can be decreased to be below 28%, no pollution is caused to environment, no odor is discharged, dry materials in a farmland become thoroughly decomposed after 50 days of landfilling, utilization value of the treated sludge is increased, and accordingly the method for curing the sludge for landfill has the advantages of simplicity in raw materials, easiness in operation control, low cost, high treating efficiency and the like.

Description

technical field [0001] The invention relates to a method for solidifying sludge as landfill garbage, and belongs to the technical field of sludge treatment. Background technique [0002] At present, with the continuous advancement of urbanization and people's increasing concern for environmental protection, the sludge generated in the process of urban domestic sewage treatment and its disposal have become an increasingly serious problem. In recent years, although my country has carried out a lot of work in the treatment and disposal of sludge, due to economic and technological reasons, my country's sludge treatment capacity is still very weak, mainly in: 1. The sludge treatment rate is extremely low; 2. Heavy water is light The development of mud and sludge treatment lags behind; 3. The technical route is mechanical; 4. It is difficult to supervise; 5. The investment is small and the policy is not perfect. [0003] Due to the management and technical defects related to sewag...
