Abstract

The invention discloses a steel plant wastewater treatment agent and a preparation method thereof. The wastewater treatment agent is prepared from the following raw materials in parts by weight: 10-15 parts of polyacrylamide, 8-15 parts of sodium carbonate, 5-10 parts of aluminum polychloride, 10-15 parts of diatomaceous earth, 5-10 parts of sunflower stalks, 2-5 parts of bamboo powder, 2-5 parts of sodium hydroxide, 10-15 parts of pulverized fuel ash, 5-8 parts of nano-attapulgite, 2-8 parts of lignin, 2-5 parts of sucrose fatty acid ester and 50-150 parts of distilled water. The steel plant wastewater treatment agent can be used for effectively reducing the content of COD, SS, petroleum and sulfide in the steel-making wastewater, and has a stable effect, a good precipitation effect and good quality of yield water reaching the emission standard. The steel plant wastewater treatment agent has low treatment cost, high purity and no toxicity, and does not cause the problems of influence on operators or secondary pollution after treatment.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a steelworks wastewater treatment agent and a preparation method thereof. Background technique [0002] Water is the source of life. In people's traditional concept, water is inexhaustible. However, with the continuous advancement of urbanization, people's demand for water resources is increasing. After entering the new century , water resources have been depleted and polluted. my country's urban domestic sewage discharge is increasing day by day, but the sewage treatment rate is low, less than 50%, so it is very important to strengthen the treatment of domestic sewage. [0003] Steelmaking wastewater refers to the wastewater discharged from the main and auxiliary production processes in the steelmaking process. The current steelmaking method is generally converter steelmaking, and pure oxygen top-blown converter steelmaking is the main method, so that the equipment tha...
