Description
Technical field
The present invention relates to a kind of rubber vulcanizing accelerator CBS (N- cyclohexyl -2- benzothiazole sulfonamide molecular formula:
C13H16N2S2) processing method of waste water is specifically a kind of by adsorbent absorption synthesis process waste water in production process
In organic matter reduce waste water COD, and external in not introducing system that is, by the way that homemade adsorbent, stirring, separation is added
Substance reaches the 50-70% for directly applying waste water total amount, reduces the discharge amount of waste water, has saved processing cost.
Background technique
Rubber vulcanizing accelerator CBS is one of common delayed action accelerator, when having scorching quality excellent and vulcanization
Between short two big advantage.With accelerant MBT, TMTD, the stretching strength and tensile strength of vulcanizate is can be improved in MBTS and used time.The rush
Natural gum and rubber polymer into agent especially suitable for the stronger Audit For Process reinforcement carbon black of alkalinity, and it is slight to change colour, no blooming, vulcanization
Glue ageing-resistant performance is excellent, is primarily adapted for use in the industrial products such as manufacture tire, rubber overshoes, sebific duct, adhesive plaster, cable.Currently all state
The raw material that the manufacturing enterprise of internal accelerator CBS uses carry out synthetic reaction for MBT, cyclohexylamine, not according to the oxidant used
Together, sodium hypochlorite oxidization, hydrogen peroxide oxidation method, sodium hypochlorite and hydrogen peroxide mixed oxidization method, dioxygen oxidation method are broadly divided into
Deng no matter which kind of technical process deposits the problem that wastewater flow rate is big in process of production, and CBS product per ton about generates 10 tons of height
COD waste water.
With the raising of environmental requirement, the enterprise for producing accelerator CBS, which is substantially all, has focused on controlling for waste water sight
It manages and applies, but problems faced is with high salt, the high COD of waste water, applying process, there are various products quality dissatisfactions, set
The practical problems such as dosage is small.For the high content of salt problem in waste water, it is substantially all in industry and uses the clean oxidation of green
Agent replaces traditional liquor natrii hypochloritis to achieve noticeable achievement so that the salt content of waste water is greatly reduced.
Therefore, the COD of waste water how is reduced, the ratio for applying water is improved, stablizes the product quality of water jacket production, drop
The cost of low wastewater treatment reduces the discharge amount of waste water, becomes the key point for restricting industry development.Now in industry generally use
The mode of multiple-effect evaporation and the continuous multiple-effect evaporation of MVR handles waste water rear enclosure use, and wherein electric consumption is quite big, at present urgently new solution
Certainly method reduces processing cost.
Summary of the invention
The present invention relates to a kind of processing methods of waste water in rubber vulcanizing accelerator CBS production process, i.e., in discharge of wastewater
The preceding harmful components adsorbed in waste water by adsorbent, reach the 50-70% for directly applying waste water total amount, reduce production mistake
The discharge amount of waste water in journey reduces cost for wastewater treatment；Adsorbent used in the present invention is self-control adsorbent, using synthesizing
Raw material M in journey carries out pore structure and is processed into random particle, and specific grain surface product is big, and suction-operated is good, can after absorption
It is very environmentally friendly not increase and generate solid waste because of wastewater treatment directly as the direct sintetics of raw material.
Technical scheme is as follows:
The processing method of waste water in a kind of rubber vulcanizing accelerator CBS production process；The following steps are included:
1) it prepares adsorbent: preparing adsorbent using rubber accelerator MBT and water, take rubber accelerator MBT, water is added

2) obtained adsorbent is added in the waste water generated in CBS production process according to the ratio of 1-2%, is stirred
30-60 minutes, then filter press separation showed that adsorbent and COD are less than 5000mg/L qualification waste water；
3) the 50-70% set of qualified waste water total amount is used in rubber vulcanizing accelerator CBS production process.
The rubber accelerator MBT is the raw material in rubber vulcanizing accelerator CBS production process.
Adsorbent prepared by the present invention is 1-2 centimetres of blocky-shaped particle of arbitrary shape.
The present invention is using existing hydrogen peroxide and sodium hypochlorite mixed oxidization process to rubber vulcanizing accelerator CBS
Synthesis, obtains the waste water generated in production process after separation, be collected into after waste water is adsorbed by homemade adsorbent qualified useless
Water uses in next batch production process according to the ratio of 50%-70%, guarantees product quality, reduces cost for wastewater treatment.
Absorption of the present invention is to carry out adsorption treatment by homemade adsorbent.Extension is all fertile absorbers
With.
The present invention has the advantages that being reduced by the adsorption treatment to waste water in rubber vulcanizing accelerator CBS production process
The COD to 5000mg/L of waste water is used in production process hereinafter, can directly cover the waste water of 50-70%, reduces waste water
Discharge amount has saved processing cost, achievees the purpose that apply, and reduces the processing total amount of waste water, reduces cost for wastewater treatment.From row
Average product per ton in industry consumes 10 tons of water, is reduced to 4 tons or so.Meet national environmental protection policy requirements, while passing through self-control
Adsorbent does not give system to introduce other impurity, and waste water applies that rear product quality is unaffected, and product purity meets product country
Standard requirements.
