Problems solved by technology

[0002] 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 treatment, it will seriously pollute the ecological environment. At the same time, due to the complex water quality and high organic content of rubber wastewater, it is very difficult to treat, especially It is the wastewater discharged from the production of styrene-butadiene rubber
Generally, the production of chloroprene rubber adopts the calcium carbide method, and a large amount of high-concentration organic wastewater is produced during the production process. The water is highly toxic and contains a large amount of organic matter that is difficult to biodegrade, such as benzene series, dispersants, curds, etc. Such as acetylene, acetaldehyde, chloroprene, benzene, chlorobenzene, copper, etc., are industrial wastewater that is seriously polluted and extremely difficult to treat. The treatment of this wastewater has always been a difficult problem for enterprises, and related very little research
[0003] The production process of the product produces a large amount of high-quality fractional wastewater containing raw materials and additives. If it is discharged directly without treatment, it will inevitably cause certain pollution hazards to the sewage water. If it is discharged into the existing biochemical treatment device, it will be Impact on the biochemical treatment unit, therefore, the wastewater must be pretreated

Embodiment 1

[0051] The process of rubber accelerator production waste water treatment water purification agent treatment waste water comprises the following steps:

[0052] (1) Add acid to the waste water to neutralize it to a pH of 6.9-7.2;

[0053] (2) Add a defoamer to the wastewater in step (1), and then undergo aeration and defoaming treatment for 3 hours. The defoamer accounts for 0.12% of the weight of the wastewater;

[0054] (3) Add flocculation water purifier to the wastewater in step (2), polyaluminum chloride 16, polyacrylamide 12, ferrous sulfate 8, aluminum sulfate 10; flocculation water purifier accounts for 0.08% of the total weight of wastewater Add microbial water purifying agent again, and its addition accounts for 0.1% of waste water gross weight;

[0055] The parts by weight of the microbial water purifying agent are: 1.2 parts of nitrifying bacteria powder, 0.9 of denitrifying paracoccus powder, 0.6 of sulfur bacteria powder, 0.8 of aniline degrading bacteria powder...

Abstract

The invention belongs to the technical field of environmentally water treatment and particularly relates to a treatment process for rubber accelerator production wastewater. The treatment process for rubber accelerator production wastewater comprises the following steps: (1) adding an acid into the wastewater to neutralize till the pH is 6.5-7.5; (2) adding a defoamer into the wastewater in the step (1) and aerating and defoaming for 3-6 hours; (3) adding a microbial water purifier into the wastewater in the step (2); (4) adding an enzyme preparation into the wastewater in the step (3); and (5) feeding the water body in the step (4) into a settling pond and filtering. The sewage treatment process provided by the invention is good in water purifying effect, fast in water purifying speed, high in safety and free of secondary pollution. By using a material with a desorption capacity as a raw material, sewage is treated by being assisted by microorganisms, so that the process is wide in application range, and the treated water is extremely high in transparency and can be recycled.
