Problems solved by technology

Although the magnetic nanomaterials in the above patent application have the advantages of low cost, high catalytic efficiency, good thermal stability, no secondary pollution and recyclable and repeated use, it is difficult for pure magnetic nanomaterials to decompose organic pollutants in sewage
[0005] The invention patent application with the publication number CN1876574A claims to protect a method for decomposing and treating organic matter in kitchen wastewater. The method discloses that pineapple enzyme has the function of decomposing animal and vegetable waste oil, protein, and starch in kitchen wastewater, but sewage usually also contains A large amount of phenol, aniline, nitrophenol and other analogues cannot be discharged up to standard with a single biological enzyme treatment

Abstract

The invention relates to the field of sewage processing, in particular relating to a composite material for processing sewage. The composite material for processing sewage is prepared from 28-48wt% of magnetic multi-wall carbon nano tube, 12-26wt% of bromelin and 28-50wt% of additive through the following steps: adding a proper quantity of water into the magnetic multi-wall carbon nano tube, and causing the magnetic multi-wall carbon nano tube to evenly disperse in the water; adding glutaraldehyde to prepare a multi-wall carbon nano tube carrier containing an active ester group; then adding into an ethyl[3-(dimethylamino)propyl] carbodiimide hydrochloride aqueous solution; adding a phosphate buffer solution (PBS) containing bromelin and glutaraldehyde for oscillatory reaction; and finally, washing with distilled water, and mixing with the additive after vacuum drying. The composite material disclosed by the invention can simultaneously carry out chemical oxidation and biodegradation processing for sewage and provides necessary conditions for simplifying the sewage processing process, effectively shortening the process flow and reducing the equipment and facility investment.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a purifying agent added to water, which is suitable for the treatment of river surges, domestic sewage and industrial waste water. Background technique [0002] With the continuous increase of the global population, the continuous development of society, and the continuous acceleration of urbanization, the volume of urban sewage and the volume of factory wastewater and sludge are increasing at an alarming rate. The organic pollutants in industrial wastewater are often highly toxic, which seriously pollutes the water environment. However, a large amount of oil is often retained in urban wastewater, which causes bacteria to breed in the water body and emits a foul smell. The cost of investment in treatment is very high, and it often cannot be maintained for a long time. [0003] The common organic pollutants in industrial wastewater contain phenol and its analogues, which are highl...
