A mathematical equation of showing the recoverin process for a mixed mono-phenols was established. It is shown that PPP(Percentage of Precipitation of Phenols) was determined by pH value and Ba2+ concentration at precipitation equilibrium as well as the original concentration of phenols.

Recovery of phenols by precipitation method using Ba2+ as a precipitant and m -cresol as a typical phenolic compound was systematically studied in this paper for the first time. A mathematical equation of showing the recoverin process for a mixed mono-phenols was established. It is shown that PPP(Percentage of Precipitation of Phenols) was determined by pH value and Ba2+ concentration at precipitation equilibrium as well as the original concentration of phenols. The theoretic values of PPP calculated from the model coincided well with the experimental results, A calculation method and theoretic basis for the engineering design of recovery of phenols is suggested using the proposed method, percentage of recovery of phenols for a distilled fraction(170~210℃)of MRF coal tar could reach 90% and percentage of dephenolizing could be more than 95%for different coking wastewater containing phenols, This study exploits a new route for recovering phenolic compounds from coal tar and wastewater containing phenols.

本文以m-甲酚为代表性酚类,Ba(2+)离子为沉淀剂首次采用沉淀法对酚类的回收过程进行了系统研究。获得了混合一元酚类回收过程的数学方程。结果表明,酚类沉淀率(PercentageofPrecipitationofPhenols)是沉淀平衡后的pH值、Ba(2+)离子浓度以及酚类原始浓度的函数。该方程与实验结果验证得极好,为进一步研究和认识离子沉淀法回收酚类过程以及指导工程设计提供计算方法和理论依据。该法对MRF(MultistageRotaryFurnace)低温热解焦油170~210℃馏分中酚类回收率可高达90%,对焦化含酚废水的脱酚率>95%。

Phenol and its derivatives are widely used as raw materials in many chemical and pharmaceutical, petrochemical industries and related industries. The aqueous effluents from these industries containing phenolic compounds are toxic and cause considerable damage and threat to the ecosystem in water bodies and human health. Therefore the removal of phenol wastewater is of environmental interest. In this paper, Degradation of phenol in artificial wastewater containing phenol with the concentration of 1 603.5 mg· L- 1 was investigated in a cell with SnO2 electrodes using different fillings as particle electrodes. This reactor designed was comprised of SnO2 film electrode as the anode together with stainless steel plate as the cathode and fillings. SnO2 film electrodes were prepared by the standard spray hydrolysis method and different fillings were packed between the two electrodes as particle electrode. The influencing factors of the reactor in treating phenolic wastewater in the sequent batch runs were researched. The results showed that this reactor could remove phenol much more efficiently than conventional three- dimensional electrode did. Furthermore, the phenol removal efficiency depended on the electrolysis time, pH values, the cell voltage, solution conductivity and the number of repeated electrolyses. When using GAC (granular activated carbon) as the fillings, the phenol removal efficiency could reach as high as 86% . The most favorable parameters were: electrolysis voltage 12 V, current 0.24 A, reaction time 30 min, pH ranged from 3 to 5, the concentration of sodium chloride, as the effective additional reagent, being 0.3% of wastewater. The reactor maintained more than 86% phenol removal efficiency after 60 runs. Effects of SiO2 sand or MnO2 sand as particle electrodes packed between the two main electrodes on phenol treatment (with the phenol reduction 70% and 83% , respectively) were also studied. The removal results were satisfied when using the reactor in treating the true phenol- containing coking wastewater from a gasworks, and we concluded that particle electrodes reactor could efficiently degrade phenol wastewater and might be a feasible and safe alternative process for the toxic organic wastewater treatment.
