Problems solved by technology

At present, the methods for treating cyclohexanone wastewater mainly include extraction and electrochemical methods, but there are still relatively few studies on the treatment of cyclohexanone wastewater by micro-electrolysis, so it is far from meeting the needs of harmless treatment of cyclohexanone wastewater

Abstract

The invention relates to ceramsites for treating cyclohexanone waste water and its preparation method and use. The ceramsites comprises cathode ceramsites and anode ceramsites. The cathode ceramsites comprise clay, dried sludge and a binder and have bulk density of 850 to 900kg / m<3>, grain density of 1200 to 1300kg / m<3> and water absorption of 12 to 13wt%. The anode ceramsites comprise clay, iron filings and a binder and have bulk density of 910 to 950kg / m<3>, grain density of 1400 to 1500kg / m<3> and water absorption of 14 to 15wt%. The ceramsites have low grain density, can effectively prevent filler hardening and can greatly improve reactor backwashing efficiency. The preparation method utilizes waste iron filings and sludge as materials for preparation of the ceramsites, saves clay and realizes solid waste resource utilization.

Description

technical field [0001] The invention relates to ceramsite for treating cyclohexanone wastewater, a preparation method and application thereof, and belongs to the technical field of solid waste recycling and wastewater treatment. technical background [0002] Sludge is a by-product of wastewater treatment, which contains pollutants and unstable pathogens such as a large amount of organic matter, heavy metals and pathogenic bacteria, which is extremely harmful to the environment. At present, the most common method of final disposal of sludge is landfill, but landfill will cause soil pollution and degradation of urban landscape. Therefore, in order to prevent secondary pollution and realize sludge reuse, it is necessary to find a suitable method that can effectively treat a large amount of sludge. Iron filings are a kind of solid waste produced in the production process of machinery factories. A large amount of iron filings not only occupies a lot of land, but also causes envi...
