Problems solved by technology

The biggest disadvantage of this method of physical chemistry + biochemical combination is that it only simply transfers or dilutes the pollutants, which consumes a lot of water treatment chemicals, which not only costs high, but also causes secondary pollution, and a large amount of inorganic salts are discharged into the environment. It will cause the harm of soil salinization. Some auxiliary wastewater such as vulcanization accelerator NS wastewater will change color and increase in chroma after biochemical treatment, which cannot meet the relevant dis

Abstract

The invention belongs to the technical field of environment-friendly water treatment and particularly relates to a treatment method of rubber accelerator production wastewater. The treatment method comprises the following steps: (1) carrying out acid neutralization on wastewater until the pH value is 6.5-7.5, and carrying out multiple-effect evaporation and desalination; (2) adding a defoaming agent into the wastewater in the step (1), and carrying out aeration defoaming; (3) adding a microbial water purifier into the wastewater in the step (2); (4) adding an enzymic preparation into the wastewater in the step (3); and (5) oxidizing and adsorbing the wastewater in the step (4). By virtue of the sewage treatment method, the water purification effect is good, the water purification speed is high, the safety is high, and the secondary pollution is avoided; the wastewater is treated by taking materials with the adsorption capacity as the raw materials and supplementing microorganisms, the use range is wide, and the treated water is extremely high in transparency and can be recycled.

Description

technical field [0001] The invention belongs to the technical field of environmental protection water treatment, and in particular relates to a method for treating wastewater produced by rubber accelerators. Background technique [0002] With the development of the rubber industry, the rubber additives industry has also been rapidly developed and expanded, and is marching towards the direction of scale and intensification, and has a pivotal position in the global industry. The rubber industry is one of the major drainage households in the petrochemical industry. Its drainage water quality is complex and changes greatly. For example, rubber accelerator wastewater contains more refractory organic matter. It is difficult to achieve the ideal by direct physical clarification or chemical reagent treatment. Governance effect. The wastewater produced in the synthetic rubber production process has a large amount of discharge and strong toxicity. If it is discharged directly without...
