| titleOfInvention | Steel wastewater treating agent and method for treating wastewater by using same |
| abstract | The invention provides a steel wastewater treating agent and a method for treating wastewater by using the treating agent, and relates to the technical field of wastewater treatment. The wastewater treatment agent is prepared from the following raw materials in parts by weight: 20-30 parts of polyacrylamide, 4-6 parts of ferrous sulfate, 12-16 parts of polyaluminium chloride, 4-8 parts of zeolite, 2-4 parts of cobalt acetate and 1-2 parts of bauxite powder. The method for treating wastewater by using the treating agent comprises the following steps: the method comprises the steps of pretreatment of steel wastewater, catalytic precipitation, treatment of precipitate by a treating agent, distillation and purification and the like. The invention overcomes the defects of the prior art, improves the treatment efficiency of the steel wastewater, enhances the purification degree of the wastewater, obtains recyclable water by treatment under the condition of ensuring no pollution, reduces the economic loss in the steel production process, conforms to the principle of environmental protection production and reduces the waste of water resources. |
