Case 1: Domestic Sewage Treatment and Reuse
The new campus of Guizhou University of Finance and Economics is a key project in Guizhou Province, which is highly valued by the people's governments of Guizhou province, city and district. In order to ensure that the sewage treatment project is effectively treated when the new campus of Guizhou University of Finance and Economics starts to use 20 1 1, it is decided to treat domestic sewage 1200 tons every day. The sewage in the new campus is treated by the "Diversion Biological Aerated Filter (CCB)" jointly developed by Chongqing Chutian Environmental Engineering Co., Ltd. and Guizhou Great Wall Environmental Technology Co., Ltd. On the premise of not increasing the project investment, the sewage treatment results reach the Water Quality of Urban Miscellaneous Water for Urban Sewage Reuse (GB/T 18920-2002) and the water quality standard of urban sewage reuse landscape environment.
Case 2: Hospital Sewage Treatment and Reuse
In 2009, Chongqing Chutian Environmental Engineering Co., Ltd. and Guizhou Great Wall Environmental Technology Co., Ltd. jointly designed and constructed the first domestic hospital sewage reuse project in Panzhihua Third People's Hospital, Sichuan Province, and accumulated valuable experience. On the basis of summarizing the experience in 20 10, Chongqing Chutian Environmental Engineering Co., Ltd. and Guizhou Great Wall Environmental Technology Co., Ltd. undertook the sewage reuse project of the affiliated hospital of Chengde Medical College in Hebei Province, and won the approval of Chengde Municipal Government, Municipal People's Congress and CPPCC.
Case 3: Treatment of Wastewater Pollution in Food Industry
For the treatment of food industry wastewater pollution, if it is not "three high" wastewater, it is best to use diversion biological aerated filter. Chongqing Chutian Environmental Engineering Co., Ltd. and Guizhou Great Wall Environmental Protection Technology Co., Ltd. adopted air flotation+diversion biological aerated filter in Guizhou Yonghong Food Factory, and the treated water can be reused as reclaimed water. Chongqing Chutian Environmental Engineering Co., Ltd. and Guizhou Great Wall Environmental Protection Technology Co., Ltd. adopted air flotation+diversion biological aerated filter in the slaughterhouse of Guizhou Weining Industrial Group, and the treated water was discharged into natural water. Chongqing Chutian Environmental Engineering Co., Ltd. and Guizhou Great Wall Environmental Protection Technology Co., Ltd. adopted air flotation+diversion biological aerated filter in Qingzhen slaughterhouse in Guizhou, and the treated water reached the first-class A standard of urban sewage treatment.
Case 4: Halogen product wastewater treatment
The other is the wastewater from halogen products. Synergistic catalytic oxidation and diversion biological aerated filter have absolute advantages. For example, Chongqing Zhubafu Food Company produces chicken feet with pickled peppers, duck feet with pickled peppers and goose feet with pickled peppers. Because the wastewater contains high oil and salt, and the pigment is large, BOD is above 9500mg/l, COD is above 4800mg/l, SS is above 600mg/l, and ammonia nitrogen in SS is above 200mg/L. Because a single biochemical method can't solve the problem, Chongqing Chutian Environmental Engineering Co., Ltd. and Guizhou Great Wall Environmental Protection Technology Co., Ltd. finally chose the cooperative catalytic oxidation split-flow biological aerated filter, and the treated wastewater reached the standard of reclaimed water.
Case 5: Pickled product wastewater treatment
There is also an absolute advantage in the treatment of pickled product wastewater by synergistic catalytic oxidation. For example, the pickle wastewater of Chongqing Yuquan Zhacai Group is first treated by anaerobic+aerobic biochemical method. Because the treatment was not up to standard, it was reformed three times, and the treatment effect was not ideal. Finally, Chongqing Chutian Environmental Engineering Co., Ltd. and Guizhou Great Wall Environmental Protection Technology Co., Ltd. adopted synergistic catalytic oxidation+diversion biological aerated filter.
Case 6: Pharmaceutical Wastewater Treatment
The wastewater discharged from Zheng Guang Pharmaceutical Factory in Guizhou has the characteristics of high concentration, refractory and non-biochemical. The sewage from Chongqing Chutian Environmental Engineering Co., Ltd. and Guizhou Great Wall Environmental Protection Technology Co., Ltd. has reached the first-class A standard of urban sewage treatment after being treated by synergistic catalytic oxidation and diversion biological aerated filter.
Collaborative catalytic oxidation diversion biological aerated filter has complete sets of equipment in Chongqing Chutian Environmental Protection Engineering Co., Ltd. and Guizhou Great Wall Environmental Protection Technology Co., Ltd., which can be directly contacted.
