▎ 摘　　要

NOVELTY - A wastewater treatment agent comprises 30-40 wt.% modified bentonite, 20-40 wt.% silicon dioxide adsorbent, 5-10 wt.% flocculating agent, microbial bacteria; amino trimethylene phosphonic acid, polyaspartic acid, 1-5 wt.% chitosan-graphene composite material, and 5-10 regulator. The microbial bacterium is prepared by 40-60 vol.% Bacillus subtilis and 40-60 vol.% yellow bacillus. The number average molecular weight of the polyasparic acid is 100000-200000. USE - The wastewater treatment agent is useful for removing pollutants in wastewater including domestic sewage and industrial wastewater, high-concentration ammonia nitrogen wastewater derived from the petrochemical industry, non-ferrous metal chemical metallurgy, chemical fertilizer, fine chemical engineering, medicinal chemical industry, and meat industries. ADVANTAGE - The wastewater treatment agent can effectively remove pollutants in the wastewater, and there is no secondary pollution. It is simple, easy to operate and suitable for industrial production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the preparation method water processing agent.
