Abstract
The invention discloses a method for treating rubber antioxidant (RD) production wastewater. The method includes using acid to adjust potential of hydrogen (PH) of original RD wastewater to be 2.5, pouring the wastewater into a container equipped with an iron-carbon electrode, and performing micro-electrolysis for 2-4 hours; filtering the treated wastewater, adding 10-20 mg/L of hydrogen peroxide with 30% mass concentration, using the acid to adjust the PH of the wastewater to be 3, and performing Fenton oxidization for 2-4 hours; and filtering the Fenton oxidized wastewater, adding 3-5 mg/L polymerization aluminum chloride, using aqueous alkali to adjust the PH of the wastewater to be 8-9, and performing flocculation. The treated wastewater is filtered, then chemical oxygen demand (COD) of the wastewater is measured to be under 1000 mg/L, and the color of the wastewater is obviously faded. According to the method for treating the RD production wastewater, devices are simple, the investment is small, industrialization is easy to achieve, the COD of the wastewater can be effectively reduced, the treated wastewater can be used as process water for recycling, the production costs are reduced, the phenomenon that discharged wastewater pollutes the environment is avoided, and resource recovery of the wastewater is achieved.
Description
Technical field
The present invention relates to a kind of method of processing the rubber antiager RD factory effluent, belong to the rubber antiager RD field of waste water treatment.
Background technology
Chemical industry is the mainstay industry of China, and along with the development of economy and the raising of people's living standard, increasing people begins the concern for the environment problem.This also causes relevant departments that the emission standard of chemical industry is constantly improved.Can environmental issue have developed into the bottleneck problem that survive for a chemical enterprise.Under so large situation, wastewater treatment has also been put on agenda.
Rubber antiager RD waste water alkalescence is large, and organic content is high, and organism is difficult to be degraded by biochemical treatment.The treatment process of present rubber antiager RD is mainly simple catalyzed oxidation, and it is processed as coal water slurry.
The present invention can effectively reduce the COD of waste water by a series of means such as little electrolysis, Fenton oxidation, flocculations, can effectively avoid again the coal water slurry topsoil that organism can not fully burn and cause in combustion processes.
Summary of the invention
A kind of processing RD factory effluent, the method that can reuse of providing is provided.The method process is simple, is easy to industrialization.
In order to achieve the above object, the present invention is realized by following technical proposals:
A kind of method of processing the rubber antiager RD factory effluent, step is as follows:
1) with acid former RD waste water is transferred pH=2.5, pour in the container that the iron carbon dioxide process carbon electrode is housed little electrolysis 2-4h into;
2) with the above-mentioned waste water filtering of handling, adding the 10-20ml/L mass concentration is 30% hydrogen peroxide, transfers pH=3, Fenton oxidation 2-4h with acid;
3) with the waste water filtering behind the Fenton oxidation, add the 3-5mg/L polymerize aluminum chloride, transfer pH=8-9 with alkaline solution, flocculation.
Waste water filtering through above-mentioned processing is surveyed COD, and COD is all at (raw wastewater COD is more than 10000mg/L) below the 1000mg/L, and color is obviously thin out.
The addition of above-mentioned steps 1 agents useful for same in the step 3 is not all to calculate as benchmark through the volume number of the former RD waste water of any processing.
The acid that the present invention mentions is various mineral acids, and such as sulfuric acid, hydrochloric acid, the alkaline solution of mentioning is various inorganic alkali solutions, such as sodium hydroxide solution, potassium hydroxide solution.
The invention has the advantages that equipment is simple, less investment, be easy to industrialization, can effectively reduce the COD of waste water, and the waste water after processing can be used as the process water recycling, reduce production cost, avoided the discharge of wastewater contaminate environment, realized the resource utilization of waste water.
