Description
Technical field
The invention belongs to environment-protective water processing technology field, be specifically related to a kind of rubber accelerator M production wastewater treatment method.
Background technology
Along with the development of rubber industry, rubber ingredients industry have also been obtained and develops rapidly and grow, and marches to mass-producing, intensive direction, in the global same industry, have very important status.Rubber industry is one of draining rich and influential family of petrochemical industry, and its draining water quality is complicated, and variation is comparatively large, if Vulkacit M wastewater is containing the organism of more difficult degradation, is directly difficult to reach desirable regulation effect by physics fining process or chemical reagent treatment process.The waste water that synthetic rubber production process produces, quantity discharged is large, and strong toxicity, as directly discharged without process, meeting serious pollution of ecological environment, meanwhile, because the water quality of Rubber Industrial Wastewater is complicated, organic content is high, makes its intractability very large, particularly styrene-butadiene rubber(SBR) production institute waste discharge.The production of general chloroprene rubber all adopts calcium carbide route, produce the organic waste water of a large amount of high density in process of production, this water toxicity is larger, containing a large amount of organic matters being difficult to biochemical degradation, as benzene homologues, dispersion agent, milk coagulant etc., as acetylene, acetaldehyde, chloroprene, benzene, chlorobenzene, copper etc., be a kind of seriously polluted, great trade effluent of intractability, for the process of this waste water, be a difficult problem of puzzlement enterprise, and relevant research is considerably less always.Major part small business does not have effective sewage treatment equipment and facility at all.
Produce a large amount of containing the high-quality mark waste water such as raw material, auxiliary agent in the production process of M product, as not treated direct discharge, certain pollution hazard will inevitably be caused to receiving sewage body, if enter existing biochemical treatment apparatus, then can produce biochemical treatment apparatus and impact, therefore, pre-treatment must be carried out to M waste water.
And in order to protect human health and environmental safety; realize economy and social sustainable development; green chemical industry, cleaner production are more and more subject to the attention of various countries; Rubber Chemicals Industries also must by environmental protection, safety, energy-conservation centered by; accelerate the adjustment of product structure, the principles and policies of development green rubber auxiliary agent.
Current domestic rubber ingredients enterprise mainly contains the treatment process technology such as materialization+biochemistry combination treatment technology, resin absorption technology, membrane separation technique, simple distillation technique, abstraction technique, wet method catalytic oxidation technologies to production wastewater treatment method.Materialization+the disadvantage of this method and technology of biochemistry combination is exactly only pollutent has been carried out simple transfer or dilution discharge, consume a large amount of water treatment agents, not only costly, also secondary pollution can be caused, a large amount of inorganic salt are discharged into the harm that can cause salting of soil in environment, some auxiliary agent waste water can increase as vulcanization accelerator NS waste water water meeting variable color and colourity after biochemical treatment, does not reach relevant emission request.Resin adsorption method can lose efficacy because of hole plug; Membrane separation technique requires high to suspended solids and acid-basicity, needs to carry out pre-treatment to waste water, is not suitable for; The salt content of the waste water after treatment by extraction does not change; If waste water only adopts the process of simple distillation method of evaporation, although inorganic salt can be separated with water, water outlet still can contain some organic pollutants, and water quality does not still reach the requirement of discharge.
Therefore, need improve for above-mentioned treatment process at present, design a kind for the treatment of process processing the waste water of rubber accelerator M production process.
Summary of the invention
