Energy-saving material for organic wastewater treatment

Abstract

The present invention discloses an energy-saving material for organic wastewater treatment, and the energy-saving material is characterized by including the following parts by weight of materials: 10-35 parts of ferrous chloride, 5-9 parts of concentrated hydrochloric acid, 5-14 parts of ferric sulfate, 3-8 parts of ammonia, 1-8 parts of gallic acid, 30-45 parts of shell powdered shell, 5-9 parts of PC (poly carbonate), 10-16 parts of PA (polyamide), 5-16 parts of diatomite, 5-16 parts of sepiolite, 1-8 parts of stearate and 3-9 parts of stearic amide. The beneficial effects of the energy-saving material are that: the energy-saving material can absorb a large amount of degradation-resistant organic pollutants, after adsorption, the organic pollutants can be quickly separated from the water along with a magnetic nano material in the presence of an external magnetic field to achieve purposes of high removal efficiency of the pollutants and wastewater purification, and the energy-saving material has a strong practical value.

Description

technical field [0001] The invention relates to an energy-saving material for treating organic waste water. Background technique [0002] At present, the adsorption method is one of the commonly used methods for the advanced treatment of sewage, which has the advantages of high efficiency and easy operation. Nanotechnology is one of the hot research technologies in the world today. Nanomaterials (at least one dimension is 100nm) have a large specific surface area, and their special structure determines their special physical and chemical properties. Nanoscale adsorbents have higher adsorption capacity and adsorption efficiency than corresponding non-nanoscale substances. Although the adsorption effect of nanoparticles is outstanding, there are mainly two problems in application: (1) Due to the small size of nanoparticles, they will be in the form of colloids after they are completely dispersed in water during the adsorption process, resulting in difficulties in solid-liquid...

AI Technical Summary

Problems solved by technology

Although the adsorption effect of nanoparticles is outstanding, there are mainly two problems in application: (1) Due to the small size of nanoparticles, they will be in the form of colloids after they are completely dispersed in water during the adsorption process, resulting in difficulties in solid-liquid separation after adsorption. Affect the water effluent effect, and if the separation is not complete, the nanoparticles may flow into the environment and cause a greater negative impact on the ecological environment

(2) Because most of the inorganic nanoparticles are polar substances, and there are many radicals on the surface, it is easy to form a stable dispersion system with water, resulting in the poor adsorption and removal effect of inorganic nanomaterials on polycyclic aromatic substances.

However, the defect of magnetic nanomaterials is: since the surface of magnetic nanomaterials has abundant radicals and strong hydrophilicity, the effect of adsorbing refractory organic pollutants in wastewater is relatively poor.
