The m-cresol degrading composite strains were isolated from the aerobic sludge of coking wastewater of Guangdong SGIS Co. Ltd.，and were named CDMs (cresol degrading micro-organisms) according to their function. In shaking flasks experiments，the effects of degradation conditions were studied and the optimum pH，inoculums amount，temperature and concentration of metal ions usually present in wastewater were determined. At pH 6.2~7.2，inoculums amount 10%~15% and temperature 35~40 ℃，the degradation of m-cresol was efficient. The presence of K+，Na+，Ca2+，Fe3+ and Mg2+ ions could improve the biodegradation ability when they were 50 mg/L，2000 mg/L，3 mg/L，1.5 mg/L and 4~10 mg/L respectively while the presence of Cu2+ ion could restrain the reaction seriously. Under specified conditions，the degradation with different initial concentrations exhibited first order kinetics characteristics. When the initial concentration was 551 mg/L，the average degradation rate reached a maximum，8.4 mg/ (L·h)，and the composite strains were the most efficient and toxicity-resistant for m-cresol degradation.

La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF) precursor powder was synthesized by the urea combustion method as cathode catalyst. From the XRD patterns，fine powders with perovskite structure were obtained by calcining at 800 ℃.

Potassium nitrate was added to intensify the chromite decomposition process by KOH sub-molten salt. The effects of the mass ratio of alkali-to-ore，the mass ratio of KNO3-to-ore，oxygen partial pressure，gas flow rate and reaction temperature on the decomposition of chromite ore were experimentally studied to determine the chromite decomposition parameters by KOH-KNO3 binary sub-molten salt. The results showed that reaction temperature and the ratio of alkali-to-ore were most significant factors on the chromium conversion efficiency. The effects of oxygen partial pressure and flow rate were less significant. The ratio of KOH-to-ore decreased from 4∶1 to 2∶1 after adding KNO3 to KOH sub-molten salt. The kinetics equation of chromite decomposition was“1+2(1－x)－3(1－x)2/3=kt”，and the apparent activation energy was 55.63 kJ/mol，which agreed with the inner-diffusion control model. KNO3 played a significant role in oxygen transfer，which obviously promoted the decomposition of chromate ore.

Ce4+/13X zeolite was prepared by the ultrasound-assisted ion exchange method，and its desulfurization performance for sulfur compounds from model gasoline (sulfur content 23 mg/kg) was evaluated by using static adsorption experiments. The effect of adsorption conditions on the desulfurization performance of the adsorbent was also studied. The results showed that the loading capacity and rate of the Ce4+/13X were significantly improved as compared with the conventional ion-exchange method. XPS analysis indicated that the use of ultrasound promoted the distribution of Ce ions on the surface of the adsorbent. And the adsorption capability of thiophene on Ce4+/13X was also superior to that prepared by the conventional method. Under the conditions of adsorption：desulfurization time 2.5 h，mass ratio of adsorbent to fuel 0.0072，the adsorption capacity of thiophene was 0.07653 mmol/g，and the best desulfurization rate could reach 76.5 %. The adsorption equilibrium data for thiophene on Ce4+/13X were tested and fitted with the Freundlich model. The saturated adsorbent can be regenerated with calcination at 450 ºC for 2 h in air，and about 95 % of the desulfurization capacity was recovered.

Bromamine acid (1-amino-4-bromo-anthraquinone-2-sulfonic acid sodium) aqueous solution was selected as the sample in this study. Separation of organic matter in bromamine acid aqueous solution by natural cold energy in winter，and the change of organic matter in freezing field were investigated. The results indicated that the ice sample can be obviously divided into four layers as slightly polluted layer，clean layer，mixed layer and precipitated layer after bromamine acid aqueous solution was completely frozen. With the increase of initial concentration，the organic removal rate decreased in the slightly polluted layer. In the clean layer，with the initial concentration from 50mg/L to 4000mg/L，its volume decreased from 76.5％ to 35.3％ of the total sample volume，and its total organic carbon (TOC) kept at 6 mg/L，not affected by the initial concentration less than 2000mg/L. The slightly polluted layer can be eliminated by introducing seed ice at the solution critical temperature，and the optimal pre-cooling temperature was 1℃. There was no significant impact on freezing separation when introducing seed ice at difference initial concentrations. In the same freezing conditions，ice layer was separated，and residual solution was frozen again repeatedly. In this process，bromamine acid was separated in the form of solid granules. With repeated separation and freezing，the organic matter removal rate decreased in the ice sample separated.
