NOVELTY - A crane-electroplating-wastewater treatment agent comprises 36-38 pts. wt. apatite, 25-27 pts. wt. iron slag, 20-21 pts. wt. waste paper residue, 18-20 pts. wt. willow branches, 6-8 pts. wt. graphene, 2-4 pts. wt. sodium silicate, 6-8 pts. wt. high-gluten flour, 10-12 pts. wt. fish scale powder, 11-13 pts. wt. lipophilic lotus leaf fiber, 5-7 pts. wt. triethylenetetramine, 7-9 pts. wt. methylcyclosiloxane, 2-4 pts. wt. dodecanedioic acid, and water. USE - Crane-electroplating-wastewater treatment agent based on modified waste paper residue (claimed). ADVANTAGE - The wastewater treatment agent has uniform pore density and high adsorption efficiency. The addition of iron slag replaces some amount of apatite, thus reducing exploitation of natural apatite and effectively solving the environmental pollution caused by accumulation of iron slag. The organically modified waste paper residue added as binder has excellent compatibility with chemical adsorbent and improves organic-pollutant adsorption rate. The high-temperature calcination enables formation of component with high porosity and high bonding strength. The added binder forms a compound with other substances during calcination, and restrains the phase change of natural phosphate rock in different temperature range, internal stress, and powder degree. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of wastewater treatment agent, which involves drying and crushing willow branches, adding waste paper residue, stir-mixing, adding 10-20% soda solution, soaking at 70-90 degrees C for 24 hours, rinsing with deionized water, adding lipophilic lotus-leaf fiber and methylcyclosiloxane, ultrasonically grinding for 20-30 minutes, and drying, treating iron slag and graphene at 725-825 degrees C for 10-20 minutes, cooling to room temperature, spraying 98 %mass concentrated sulfuric acid solution in nitrogen environment, sulfonating for 15-20 minutes, filtering, washing with hot water until there is no sulfate ion, adding triethylenetetramine and high-gluten flour, magnetically stirring for 2-3 hours, and drying, calcining apatite in an oxygen atmosphere at 200-300 degrees C for 2-3 hours, cooling to room temperature, activating apatite powder, adding the prepared materials and other remaining components, mixing, spraying 10% water, granulating, drying, calcining at 700-750 degrees C for 15-20 minutes, and discharging.
