Rubber accelerant M production wastewater treatment method

Abstract

The invention belongs to the technical fields of environmental protection and water treatment, and concretely relates to a rubber accelerant M production wastewater treatment method. The rubber accelerant M production wastewater treatment method comprises the following steps: 1, adding an acid to wastewater in order to neutralize the wastewater to make the pH value reach 6.5-7.5, and carrying out multi-effect evaporation desalination treatment; 2, adding a defoaming agent to wastewater obtained in step 1, and carrying out aeration defoaming treatment; 3, adding a microbial water purifier to wastewater obtained in step 2; 4, adding an enzyme preparation to wastewater obtained in step 3; and 5, oxidizing and adsorbing wastewater obtained in step 4. The wastewater treatment method has the advantages of good water purification effect, fast water purification speed, high safety and no secondary pollution, and has a wide application range by using an adsorption material as a raw material and using microbes to carry out wastewater treatment, and water obtained through the method is extremely highly transparent 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 accelerator M. 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, the rubber accelerator M 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 ...

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 discharge requirements.

The resin adsorption method will fail due to pore blockage; membrane separation technology has high requirements for suspended solids and acidity and alkalinity, and it is not suitable to pretreat the wastewater; the salt content of the wastewater treated by the extraction method has not changed; if the wastewater is only used Simple distillation and evaporation treatment can separate inorganic salts and water, but the effluent will still contain some organic pollutants, and the water quality still cannot meet the discharge requirements
