Abstract
The invention discloses an electrolytic treatment method of wastewater generated by producing a vulcanization accelerator M, comprising the following processes: adding 500-50000mL of wastewater generated by producing M to an electrolytic cell with electrodes, taking Cu, Fe, Ti, Zn, C, stainless steel, etc as the anode, taking Cu, Fe, Ti, Zn, C, stainless steel, etc as the cathode, ensuring the current to be 1-20A, the voltage to be 1-50V, the plate distance to be 5-50cm and the plate area to be 5-50cm2, adding a catalyst which is 0.1-3% of the wastewater by mass and carrying out electrolytic treatment on the wastewater for 0.5-10h under the above conditions. The COD removal rate can reach over 98%, thus the wastewater is up to the discharge standard. The method has the following advantages: the method is simple in process, low in energy consumption, high in COD removal rate over 98%, better in treatment effect and easy for industrialization and reaches the discharge standard.
Description
Technical field
The present invention relates to the treatment process of a kind of promotor benzothiazolyl mercaptan (M) factory effluent, belong to environmental technology field.
Background technology
Captax is a kind of universal vulcanization accelerator, is widely used in various rubber items, has broad cure range, can use separately or with other accelerator combinations, also be altax, CBS, the parent of NOBS.Owing to produce a large amount of high density salt-containing organic wastewaters in the production process of captax, be difficult to handle, it produces the very big restriction that is subjected to development owing to environmental protection pressure.Waste water in the M production process is mainly derived from mother liquor and filters and washing process, and its salinity and COD concentration are higher, have color and smell, contains multiple heterocycle organism in the water simultaneously, is difficult to handle with methods such as biochemistry.Less to the improvement research report of such waste water at present, mostly be technologies such as evaporative distillation, energy consumption is big, and treatment effect is relatively poor.Document (environmental engineering, 2007,4:78) reported the treatment process design of rubber accelerator factory effluent, this article adopts and earlier highrank fuel salinity water is carried out the desalination pre-treatment with method of evaporating, and high-concentration waste water adopts little electrolysis-Fenton oxidation, flocculation precipitation method is handled, enter biochemical treatment again with after middle concentration waste water mixes, this complex process, long flow path through pretreated waste water, investment is big, and treatment effect is general.Document (Treatment of Industrial Water, 2008,7:21) reported a kind of treatment process of captax factory effluent, this method adopts complete physico-chemical process that waste water is handled, water sample carries out carrying out advanced treatment after the resin absorption earlier by pre-treatment then, and water outlet reaches emission standard; But use resin in this method, cost is higher.Based on this kind present situation, developed the method for handling this waste water with electrolytic process, this method utilizes the high salt concentration ion in the water to conduct electricity, and need not to add ionogen again.This method energy consumption is less, and treatment effect is preferable, can reach emission request fully.
Summary of the invention
The object of the present invention is to provide a kind of method with electrolytic process processing captax factory effluent, this procedure is simple, need not to add other ionogen, and energy consumption is low, is easy to industrialization.
For achieving the above object, the present invention is realized by following technical proposals: a kind of method with electrolytic process processing captax factory effluent is characterized in that comprising following process:
1. in being housed, the electrolyzer of electrode adds M factory effluent 500～50000mL, with materials such as Cu, Fe, Ti, Zn, C or stainless steels is anode, with materials such as Cu, Fe, Ti, Zn, C or stainless steels is negative electrode, electric current 1～20A, voltage 1～50V, polar plate spacing 5～50cm, pole plate area 5～50cm
2, and adding and sewage mass ratio be 0.1～3% catalyzer, with this understanding wastewater electrolytic handled 0.5～10h, the clearance of its COD can reach more than 98%, reaches emission standard.
The invention has the advantages that: this procedure is simple, and energy consumption is low, and the clearance height of COD can reach more than 98%, and treatment effect is preferable, reaches emission standard, is easy to industrialization.
