NOVELTY - Multifunctional environmentally friendly water treatment agent comprises 17-20 pts. wt. bentonite, 8-11 pts. wt. bagasse, 6-7 pts. wt. fly ash, 9-10 pts. wt. polyvinyl alcohol, 3-6 pts. wt. Calamus extract, 6-7 pts. wt. dog tooth root extract, 10-13 pts. wt. activated carbon, 2-3 pts. wt. titanium dioxide, 2-5 pts. wt. aluminum oxide, 4-5 pts. wt. graphene, 3-6 pts. wt. dispersant and 2-3 pts. wt. antibacterial agent. USE - Used as multifunctional environmentally friendly water treatment agent. ADVANTAGE - The agent: utilizes bagasse and fly ash having strong adsorption; achieves the effect of waste utilization; utilizes the Calamus extract and the dog tooth root extract extract are both super-accumulative plants; effectively adsorbs the heavy metal elements of cadmium, arsenic, nickel and copper in the wastewater; is safe and non-toxic; and does not cause secondary pollution; enhances the storage capacity of metals; has developed pore structure, large specific surface area and rich surface chemical groups; provides good adsorption; has long and empty and large specific surface area; realizes the removal of multiple pollutants in water; has simple preparation method; and is easy to operate; improves the performance of the original material; has good water treatment effect; reduces the ammonia nitrogen content; has excellent properties i.e. COD and phosphorus content; improves the service life of the material and the original shortcomings of the material; does not contain harmful substances i.e. strong acids and alkalis; and achieves excellent performance; and reflects the concept of environmental protection. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the multifunctional environmentally friendly water treatment agent, comprising (i) adding bentonite, bagasse, fly ash to the reaction kettle at 500-1000 revolutions per minute, and stirring for 20-30 minutes until fully mixed, where bentonite is a non-metallic mineral with montmorillonite as the main mineral component, highly dispersing in water and is very effective in adsorbing impurities in water, (ii) continuously adding polyvinyl alcohol to the reactor, Calamus extract, dog tooth root extract, stirring for 10 minutes at 500-1000 revolutions per minute, (iii) adding activated carbon and titanium dioxide into the reactor, adding aluminum oxide, stirring for 10 minutes at speed of 500-1000 rpm, adding activated carbon made of wood, carbon-containing raw materials i.e. coal and petroleum coke are prepared by pyrolysis and activation processing, and(iv) adding graphene, dispersant, antibacterial agent, and stirring for 10-20 minutes at speed of 500-1000 rpm in the reactor, and(v) unwinding and packaging to obtain products.
