Composite adsorption treatment material for wastewater with nitrobenzene

Abstract

The invention discloses a composite adsorption treatment material for wastewater containing nitrobenzene, which comprises the following raw materials in parts by mass: 15-30 parts of hydroxypropyl cellulose graft copolymer, 5-8 parts of oxyferric chloride, 4~10 parts of cationic etherified starch, 2~8 parts of activated carbon fiber, 5~10 parts of activated alumina, 2~6 parts of polyepichlorohydrin, 1~4 parts of porous hydroxyapatite powder, hydrophobic modified wood 5~12 parts of cellulose fiber, 6~10 parts of polyhydroxyaluminum silicon chloride, 10~18 parts of nonionic polyacrylamide and 12~20 parts of adsorbent NSUL-1. A composite adsorption treatment material for the treatment of nitrobenzene-containing wastewater provided by the present invention produces a synergistic adsorption treatment effect through reasonable raw material compounding, and has good performance on the main pollutant in nitrobenzene-containing wastewater-nitrobenzene The adsorption treatment effect, and can effectively reduce the chroma value and COD of sewage, with excellent comprehensive water treatment effect.

Description

technical field [0001] The invention relates to the technical field of waste water treatment materials, in particular to a composite adsorption treatment material for waste water containing nitrobenzene. Background technique [0002] After the 1950s, the global population grew rapidly and industries developed rapidly, accompanied by the rapid deterioration of the global water resources situation, and the "water crisis" became increasingly serious. On the one hand, the human demand for water resources is increasing at an alarming rate; on the other hand, the increasingly serious water pollution erodes a large amount of water resources available for consumption. The increasing water pollution has attracted more and more attention, especially in economically underdeveloped areas and areas with many chemical plants. The wanton discharge of untreated sewage seriously threatens the local natural environment, including Wastewater containing nitrobenzene discharged from chemical fa...

AI Technical Summary

Problems solved by technology

The existing treatment methods for wastewater containing nitrobenzene mainly include biological methods, chemical methods and physical methods. Among them, the chemical method has problems such as high treatment cost and secondary pollution, and the cost of biological treatment of wastewater containing nitrobenzene is relatively low. , but the domestication and purification of microbial strains have always limited the further development of biological treatment technology; the physical method is mainly adsorption treatment, but the adsorption effect of the existing adsorption treatment materials on nitrobenzene is not ideal
