Compound agent for advanced treatment of industrial wastewater and preparation method thereof

The invention relates to a compound medicament for advanced treatment of industrial wastewater and a preparation method thereof, and belongs to the technical field of environment-friendly water treatment.The compound medicament for advanced treatment of industrial wastewater is prepared from, by weight, 5-15 parts of activated carbon, 20-50 parts of polysilicate aluminum ferric flocculant, 5-10 parts of cationic hyperbranched polymer and 20-45 parts of silica gel-activated carbon composite adsorbent. The compound agent solves the problem that advanced treatment means after biochemical treatment has to select advanced oxidation process or evaporation process and other processes with high investment and operation cost, reduces a series of problems that the process is difficult to operate stably, the labor intensity of operators is high and the like due to water quality fluctuation, ensures that drained water meets the index requirements of advanced treatment, and has a wide application prospect.
