Along with the fast development of medicine industry in our country,make the pollution of the pharmacy wastewater with manage has caused the people high value and attention.Because the process of medicine production in the different medicine species and the production crafts which put wastewater has a large difference between the flow and water quality,make to usually imply the organic pollutant that the category are of a great variety in the medicine waste water,and also because the product replacing period is short, replace along with the product,the flow and water quantity of wastewater usually changes and unsteady,most of them have a difficulty in decline or repress the function to the microbe.And along with the produce of medicine extend continuously,a lot of wastewater flow which make older watstwater establishment has already can't satisfied to increasingly flow,how on the establishment that controls the economic costs effectively again the exaltation processing result is the point that pay attention to relatively currently.Currently at the processing research of the wastewater mainly have following three direction:l,enhance the microbe.Aim at the characteristic of pharmacy wastewater to inoculate the new microbe to enhance the processing ability;2,the new technique or new materialses of adoptions enhance to handle the unit,3,excellent turn to combine the way,or go forward to go the improvement in the original craft.But among them,pass to introduce into the new microbe to enhances the technical is more convenient,because it can advanced the competence of wasterwater establishment by not changing the original establishment up.On the foundation between domestic and international research,the experiment used the local pharmacy wastewater processing establishment in common use" hydrolytic acidifiation+SBR" craft currently,and introduced a new efficiently microbe which manufacture by the American Ecological Laboratory,INC,managed by the American BluePlanet Company -Aqua Clean(ACF32).It is a kind of good water processing preparation that implies 32 kinds of activities microbe,have already publishing for more than 30 years.The experiment passes to add that microbe to intensify the lively sludge in the process on the development and tame of the lively sludge,and compared with older lively sludge,analytical two kinds of lively sludge different effective on treatment and atart-up time. Pass through the experiment and analysises get the conclusion:(1)In the aspects of starting on the equip,the sludge which inoculated by ACF32 is better than radicai sludge from medical comply in starting-time,adapt the trait of medicine wasterwater that water quality changing largely;(2)At the stage of continuously circulate,the treatment result use sludge which inoculated by ACF32 is better than before,the reduced rate in the COD,BOD,TN,TP attain to:97.43%,95.47%,60.12%,72.35%.COD outfluent attain to:101.84 mg·L-1,22.71 mg·L-1,8.61mg·L-1,,0.73 mg·L-1,attain to the national second emission standard;(3)In the process of parameter optimization,analyzing the changing regulation and its reasons of COD,TN,TP,BOD,DO etc.parameters in the period,thus making sure in the process of treating the medicine waste water,the best movement period of the "hydrolytic acidifiation+SBR" craft is:The remain time is 6 hours;the SBR is:influent with limit time contains 0.5 hours,aeration time contains 4 hours,and subside time contains 1.5 hours;(4)analying kinetics of SBR equipment,get a parameter is:Y=0.3394,Kd=0.0169 d-1;(5)Carried on the measurement of the oxygenation ability in the SBR equipments,get a conclusion:KLa =4.31 h-1,equipment which provide oxygen have satisfied the microorganism growth need.At the same time,aim at the problems existented in experiment,put forward the place that needs improve and research:(1)Because carrying on the contrast experiment,for the sake of the easy to control, carrying on only small experiment,hope further used in meddle experiment,to expect to make use of to have the better designation function to the engineering;(2)The experiment only use ACF32 to treat pharmacy wastewater in first and second class processing,outfluent attains to the national second class standard,should consider the further used in the third depth processing,to improve the water treating standard;(3)Because of the restrict of the experiment eqiupment,further research analysis which did not do in the characteristic of microorganism in fludge.
