Problems solved by technology

[0005] When performing dehydration treatment, it is difficult to dehydrate the bound water and interstitial water in the sludge. Due to the high water content of the sludge, it often blocks the leachate collection system and drainage pipes. The high water content of the sludge makes the rheology of the sludge make it Landfills are prone to deformation and landslides

Abstract

The invention belongs to the technical field of sludge treatment, and particularly relates to a sludge conditioner and an application treatment method thereof. The sludge conditioner is composed of the following components: 10-15 parts of a filter aid, 1-5 parts of an organic acid, 10-15 parts of an oxidizing agent and 40-60 parts of ferric salt; the pH value is adjusted to be 4-6. The sludge conditioner provided by the invention is used for carrying out deep dehydration on sludge; the removal rate of heavy metals Pb and Cd in the sludge is relatively improved, and the whole technological process does not exceed 4.5 hours; the water content of the dried sludge is lower than 55%, secondary pollution is avoided, the sludge conditioner can be widely applied to sewage drying treatment of various industries, life and the like, the treated sludge is directly used for composting, incineration, building material application and the like, and the sludge conditioner has good application prospects and market prospects.

Description

technical field [0001] The invention belongs to the technical field of sludge treatment, and in particular relates to a sludge conditioner and an application treatment method thereof. Background technique [0002] The amount of sewage treated by sewage treatment plants is increasing day by day, and the amount of sludge generated by sewage treatment is also increasing. The sludge produced by the sewage plant has a complex composition, containing a variety of microorganisms, organic matter and inorganic matter, mainly including refractory organic matter, heavy metals, salts and pathogens. And most of the sludge produced by industrial wastewater contains a large amount of heavy metals. [0003] If the sludge is discharged directly without treatment, it will cause great harm to the environment. Because the sludge that has not been stabilized has a high content of organic matter, is perishable, breeds a large number of germs, parasites, etc., and is easy to cause secondary poll...
