Case 1: domestic sewage treatment and reuse
Guizhou University of Finance and Economics new campus is a key project in Guizhou Province, by the Guizhou Provincial, Municipal and District People's Government attaches great importance to ensure that Guizhou University of Finance and Economics on September 1, 2011, the opening of the use of the new campus, the sewage treatment works to be effectively dealt with, the decision of 1,200 tons of domestic sewage per day, the use of "Conductive Aeration Biofilter (CCB)" on the new campus sewage treatment, without increasing the premise of the project investment, the sewage treatment results to meet the "urban wastewater reuse urban miscellaneous water quality" (GB/T18920-2002) standards, to "urban wastewater reuse water quality of water for landscape environment" (GB / T18921-2002) in all the requirements.
Case 2: hospital sewage treatment and reuse
China's first hospital sewage water reuse project in 2009 by the Third People's Hospital in Panzhihua, Sichuan Province, the construction of success, and has accumulated valuable experience, in 2010, on the basis of summarizing the experience, the construction of Hebei Province, Hebei Province, the Affiliated Hospital of the Medical College of Chengde sewage water reuse project, has been highly praised by the Chengde Municipal Government, the Municipal People's Congress, The project was highly praised by the Chengde Municipal Government, the Municipal People's Congress and the Chinese People's Political Consultative Conference.
Case 3: treatment of food industry wastewater pollution
Treatment of food industry wastewater pollution, if it is not the three high wastewater, it is best to use the inflow aeration biofilter, Guizhou Yonghong food factory using air flotation + inflow aeration biofilter, the treated water to achieve water reuse, Guizhou Weining Industrial Group slaughterhouse using air flotation + inflow aeration biofilter, the treated water is discharged into the natural water body, Guizhou Qingzhen slaughterhouse. The slaughterhouse in Qingzhen, Guizhou adopts air flotation + inflow aeration biofilter, and the treated water reaches the primary A standard of urban sewage treatment.
Case 4: halogenated products wastewater treatment
The other is halogenated products wastewater, the use of synergistic catalytic oxidation + inflow aeration biofilter, with absolute advantages, such as Chongqing pig eight blessed food company production of pickled pepper phoenix claw and pickled pepper duck feet, goose palms, etc., due to the wastewater containing oil, salt are very high, pigmentation, BOD in the 9500mg / l or more, COD in the 4800mg/l or more, SS in 600mg/l or more, ammonia nitrogen in SS in 2880mg/l or more, due to a single biochemical method can not be solved, the final choice of synergistic catalytic oxidation + inflow aeration biofilter, the treated effluent to meet the standard of water.
Case 5: pickled wastewater treatment
There is also pickled wastewater, the use of co-catalytic oxidation, but also, with absolute advantages, such as the Chongqing fish spring pickle group of pickled wastewater, the company's first anaerobic + aerobic biochemical treatment, due to the treatment is not up to standard, and then three times the transformation, has invested more than 3,000,000 yuan, the treatment effect is unsatisfactory!
The company first used anaerobic + aerobic biochemical method for treatment, because the treatment did not meet the standard, and then invested more than 30 million RMB for three times, the treatment effect was not satisfactory.
Case 6: pharmaceutical wastewater treatment
The wastewater discharged from Guizhou Guangzheng Pharmaceutical Factory is characterized by high concentration, treatment difficulty, and not biochemical, etc., and the use of synergistic catalytic oxidation + inflow aeration biofilter treatment to achieve the urban wastewater treatment of primary A standard.
Synergistic catalytic oxidation and inflow aeration biofilter in Chongqing Chutian Environmental Protection Engineering Company Limited and Guizhou Great Wall Environmental Protection Science and Technology Co.
