SBR与SBBR法处理制药废水对比试验

制药废水属于高浓度含微生物难降解,对微生物有抑制作用的有机废水,水质水量波动大,本文对制药厂厌氧处理出水,分别采用SBR和SBBR法进行对比试验,研究其COD去除效果。当曝气量控制在0.02m3/h,沉淀时间在2h时,在2~10h反应时间段内,对比了SBR和SBBR法对CODCr的去除率。试验结果表明:总体上,SBBR法CODCr去除效果优于SBR,且更稳定,CODCr去除率能达到90%以上,而SBR在反应时间6h时达到CODCr最大去除率:82.03%后,出水中CODCr不降反升。

Seed yeast cultivation for salad oil manufacturing wastewater treatment

The mixture of five yeast strains obtained from soil could remove about 85% TOC of oil-rich wastewater in batch test.While the highest MLSS was obtained at an N:C of 1:5,the oil removal decreased with the increase of N:C during yeast sludge cultivation.Ammonium chloride was the best nitrogen source for yeast cultivation from the viewpoint of yeast growth and oil utilizxation.An ammonia concentration of over 1300 mg/L led to mass death of yeast at a pH of 5.The ammonia concentration should be controlled at a level of 1000 mg/L or lower.     

论突发地质事件与形成胶莱盆地金矿关系

中生代后期 ,太平洋板块的俯冲作用使胶南地体拉分 ,断陷形成胶莱盆地。这一突发地质事件在盆地底部地势低洼部位形成局限水体 ,接受周围古老地层风化剥蚀产物的沉积而形成富含有机质、富金的莱阳群一段含矿岩系。此突发地质事件晚期的进一步改造成矿作用导致在含矿岩系不同岩性中形成不同类型的金矿床     

利川市生活垃圾卫生填埋场场址的比选

选址是卫生填埋场建设和运行的关键。以利川市实际情况为前提和依据，筐选出7个预选场址，经实地踏勘和从填坦容量、运输距离、搬迁户数量等方面分析，遴选出其中3个；分别从工程学、环境学、经济学、社会与法律等方面中如交通状况、服务年限、占地面积、基岩类型、渗透系数、地下水位、覆盖土来源等13项具体条件上对3个备选场址进行了详细的分析比较，确定杨柳村大天井为最终选定场址。利川垃圾填埋场的选址工作也可以为同类型的城市或地区提供参考和借鉴。

含溴水源水臭氧处理时溴酸盐的产生与控制

针对南方某含溴水库水(溴离子浓度15～38μg·L-1),利用连续运行实验装置研究了臭氧氧化时溴酸盐的产生条件,同时初步考察了后续生物活性炭(BAC)对溴酸盐的去除效果.研究结果表明,单独采用预臭氧方式时,在臭氧消耗量控制为2.0mg·L-1以内的条件下,溴酸离子浓度低于6 μg·L-1;而采用预臭氧与后臭氧联合处理时,在总臭氧消耗量为2.0mg·L-1的条件下,出现了溴酸离子超标(10μg·L-1)情况.长期运行结果表明,尽管新炭对溴酸离子没有去除效果,但系统连续运行3个月后,BAC上的微生物对溴酸盐具有一定的去除能力.

Fulvic acid removal by nanoparticle TiO2 using a submerged membrane photocatalysis reactor

The degradation of fulvic acid（FA） by nanoparticle TiO2 in a submerged membrane photocatalysis（SMPC） reactor was studied. In this reactor, photocatalytic oxidation and membrane separation co-occured. The continuous air supplier provided O2 for the photocatalytical reaction and mixed the solution through an airflow controller. The particle TiO2 could automatically settle due to gravity without particle agglomeration so it could be easily separated by microfiltration（MF） membrane. It was efficient to maintain high flux of membranes. The effects of operational parameters on the photocatalytic oxidation rate of FA were investigated. Results indicated that photocatalyst at 0.5 g/L and airflow at 0.06 m^3/h were the optimum condition for the removal of fulvic acid, the removal efficiency was higher in acid media than that in alkaline media. The effects of different filtration duration on permeate flux rate of MF with P25 powder and with nanoparticle TiO2 were compared. Experimental results indicated that the permeate flux rate of MF was improved and the membrane fouling phenomenon was reduced with the addition of nanoparticle TiO2 catalyst compared with conventional P25 powder. Therefore, this submerged membrane photocatalysis reactor can faciliate potential application of photocatalytic oxidation process in drinking water treatment.
