臭氧氧化处理废乳化液试验研究
|
摘要
本课题研究的是经物化破乳后的废乳化液,其COD值高达几万,成分复杂,难降解,国家列其为危险废弃物。若处理不当,可能对生态环境、动植物和人类健康造成严重危害。通过一般的物理、化学组合工艺只能简单的油水分离,其处理后的废水COD值依然很高,因此,寻找一种高效而简单的废乳化液的深度处理方法显得尤为重要。
本课题采用单独臭氧氧化和协同氧化预处理废乳化液的试验方法,臭氧氧化技术具有强化能力强、处理成本较低,无二次污染等特点,它作为处理高浓度难降解的废乳化液具有巨大的发展前景。
本试验首先采用单独臭氧氧化考察该废乳化液氧化后的去除效果,在此基础上,通过改变pH,投加H202等条件,研究最佳条件下的废乳化液的去除效果。研究发现：单独臭氧氧化时,臭氧投加量为110.21mg/L, COD去除率仅为52.2%,色度去除率为63.6%：根据实际工业水处理需要,从降低处理成本角度出发,通过调节水样pH至10,投加1g30%H202,臭氧投加量为220.42mg/L, COD去除率为80.6%,色度去除率为84.1%。
通过试验数据可以看出,采取该技术对实际的机械加工生产废液进行预处理,COD和色度去除效果好,可以作为生化处理的预处理,为后续生化处理提供条件。
The object of the subject is waste emulsion by the physical and chemical emulsion of breaking,the COD value reach up to tens of thousand,the composition is complicated,and difficult to break down,our country delimits that it is hazardous waste. If not handle properly,it may cause serious harm to the ecological environment,Flora and fauna and people health. By the general physical and chemical combination process, it can only be a simple oil-water separator, but the COD value of the treated wastewater is still very high, so it is particularly important to find an efficient and simple way of the waste emulsion.
The test methods deal with waste emulsion by the use of ozone alone and co-oxidation pretreatment,ozonation technology has the ability of strong processing,the lower cost and no secondary pollution,it has great development in the treatment of high concentration of refractory waste emulsion.
The test firstly study the removal result after ozonation of waste emulsion, on this basis, by changing conditions of the pH and dosing H2O2, and study the removal of waste emulsion under the best conditions. The study shows that when use the ozonation independently,COD removal rate is only52.2%and the chroma removal rate is63.6%by the dosage of ozone is165.32mg/L; According to the needs of the actual industrial water treatment for the perspective of reducing the cost, adjusting the pH of the water sample to10and adding1g30%H2O2,the ozone dosage is220.42mg/L,COD removal rate is80.6%, the chroma removal rate is84.1%.
The test data shows that COD and color removal effect is great by the treat of ozonation technology in the machining production waste of pretreatment and it can pave the way for subsequent biological treatment.
