Description
Technical field
The present invention relates to a kind of haydite that is used for Treatment of Cyclohexanone Waste Water and preparation method thereof and application, belong to the technical field of useless admittedly resource utilization and wastewater treatment.
Technical background
Mud is the sub product of wastewater treatment, has comprised pollutent and unsettled pathogen such as large amount of organic, heavy metal and pathogenic bacteria, and is very big to environmental hazard.The most frequently used method of sludge ultimate disposal is a landfill at present, but landfill can cause the degeneration of soil pollution and urban look.Therefore, in order to prevent secondary pollution and to realize that mud utilizes again, need to seek the appropriate method that effectively to handle a large amount of mud.Iron filings are a kind of solid waste that produces in machine works's production process, and a large amount of iron filings not only occupy many soils, but also cause environmental pollution.How to reduce the iron filings environmental pollution and convert thereof into useful resource by broad research.
Haydite is widely used in industries such as building, chemistry, metallurgy, agricultural and environment protection.If with mud and iron filings additive, then can reduce the use clay, so also can become useful matter to pollutent as haydite production.
Micro-electrolysis method is called internal electrolysis again, by a kind of method of wastewater treatment of broad research and application.The eighties in 20th century, this method was introduced China.At present micro-electrolysis method successfully be applied to print and dye, the processing of waste water such as agricultural chemicals, pharmacy, oil content.Characteristics such as that little electrolysis has is with low cost, use range is wide, technology is simple, treatment effect is good, especially the processing for the trade effluent of high toxicity, high CODCr has clear superiority than other technologies.But traditional little electrolysis process is after operation for some time, and iron filings filler caking back sewage produces channel in filler, make the effluent quality variation, and this also is a principal element of the little electrolysis process application of restriction.Negative electrode haydite and anode haydite are a kind of low unit weight and low pellet density filler, and this will help backwash process.Therefore, they can be used as the filler of micro-electrolysis reactor electrolytic reaction groove.
Objectionable impuritiess such as the pimelinketone in the cyclohexanone industrial wastewater, hexanaphthene are very big to the harm of environment; If this type of waste water is without handling directly discharging; Then wherein material such as hexanaphthene, pimelinketone very easily accumulates in environment; They are killed in a disaster by Natural Degradation, thereby and can constitute serious harm to human health with the food chain enrichment.Therefore, the effective treating method of a Cyclohexanone Waste Water of searching is very important.At present, the method for Treatment of Cyclohexanone Waste Water mainly comprises extraction and electrochemical process, and also fewer about the research of micro-electrolysis treatment Cyclohexanone Waste Water, therefore far can not satisfy the demand to the harmless treatment of Cyclohexanone Waste Water.
