Description
Technical field
The present invention relates to technical field of waste water processing, be specifically related to a kind for the treatment of process containing 2-propoxy-monochloroethane waste water.
Background technology
2-propoxy-monochloroethane (being called for short chlorine ether) is one of important source material preparing herbicide pretilachlor, and this weedicide, as low toxicity, wide spectrum, efficiently major choice weedicide, is widely used in Rice Cropping field.Industrial basic employing sulfur oxychloride method synthesis, this technique after the completion of reaction, need add water decomposition excess thionyl chloride, produce waste water acid strong, need consume a large amount of liquid caustic soda neutralizing treatment, obtain chlorine ether and waste water through separatory, product waste water generation per ton is up to 400 ~ 600kg.Because chlorine ether has certain solubility in water, and density and aqueous phase are closely difficult to accomplish thorough separatory, containing the impurity such as a large amount of chlorine ether, catalyzer, inorganic salt in waste water, thus cause that waste water smell is large, COD
crhigh (4 ~ 5 × 10
4mg/L), color is dark, seriously limits its large-scale production and application.In addition, chlorine ether molecular formula is C
5h
11clO, molecular weight 122.59, containing ehter bond and chlorine element in molecule, determines its high volatility, and smell is large, and toxicity is high, big for environment pollution, and stability is high, biodegradability extreme difference, and slowly, the environmental hazard cycle is long in nature degraded.
Fenton reagent (Fenton reagent is called for short FR) oxidation catalysis method is considered to a kind of dealuminated USY cataluyst method of gentleness of great potential, starts to be applied to wastewater treatment from the sixties in 20th century.On the basis of traditional F R, develop again many class FR, as light-FR, electricity-FR etc., all belong to high-level oxidation technology (AOPs).It utilizes the non-selective characteristic of OH, degradable multiple types organism.FR oxidizing reaction utilizes Fe
2+catalysis H in acid condition
2o
2decompose the OH produced and carry out attack organic molecule internal key, hydroxyl radical free radical OH has high reactive behavior and oxidation capacity, and non-selectivity, it can be made to degrade so that mineralising with most of organism effect.
UV/Fenton reagent method is classical Fenton reagent and UV/H
2o
2the compound of two kinds of systems, its ultimate principle is similar to classical Fenton reagent, difference be reaction system under UV-irradiation in ferric iron and water the compound ion of hydroxide ion can directly produce OH and produce ferrous ion, ferrous ion can with H
2o
2further reaction generates OH, thus accelerates organic pollutants degradation speed; H
2o
2also OH can be generated by Direct Resolution under UV-irradiation effect; Some organic pollutants also can directly be degraded under action of ultraviolet light.
At present, the industrial process to organic chloride mainly contains Physical, biological process, chemical oxidization method and chemical reduction method, has that cost is high, performance difficulty, adaptability are little or the shortcoming such as degradation rate is low.And the most important thing is that degradation time is long, be difficult to use in huge industry, sanitary sewage disposal.Therefore, it is very necessary for researching and developing efficient, cheap, gentle dealuminated USY cataluyst method.
Summary of the invention
The object of this invention is to provide a kind of mild condition, technique be simple, degradation rate is fast, successful, with low cost, be applicable to industrializing implementation containing the treatment process of 2-propoxy-monochloroethane waste water.
Treatment process containing 2-propoxy-monochloroethane waste water of the present invention, comprises the following steps:
(1) adjustment is containing pH value to 3 ~ 4 of 2-propoxy-monochloroethane waste water;
In sulfur oxychloride method synthesis 2-propoxy-monochloroethane, after reaction terminates, water decomposition excess thionyl chloride need be added, produce hydrogenchloride major part all soluble in water, make waste water be acid strong, by adding appropriate sodium hydroxide solution adjustment waste water ph to 3 ~ 4;
(2) FeSO is added
47H
2o, is stirred to and dissolves completely;
(3) H is dripped wherein
2o
2, open LED ultra violet lamp, Controlling System temperature simultaneously, after dropwising, under LED ultra violet lamp, continue stirring 3 ~ 6 hours; According to waste water COD
crvalue determine H
