the 2018 henan (zhengzhou) sewage treatment technology and equipment exhibition was held in zhengzhou international convention and exhibition center from september 27 to 29, 2008. shenzhen qingquan-dai wenquan vice-general manager was invited to attend the opening ceremony of the exhibition, and served as a guest speaker of the summit forum of the sewage treatment technology and equipment exhibition. the whole process of construction and transformation helped.

at 9:00 a.m. on the 27th, the opening ceremony officially kicked off. more than 100 industry experts and media were present. guo fengchun, deputy director-general of the department of housing and urban-rural construction of henan province, delivered an opening speech at the meeting to welcome and thank the guests on the spot. shenzhen quan quan dai and henan provincial leaders at all levels jointly opened the curtain for the conference. after the opening ceremony, general dai and leaders at all levels to conduct on-site patrol exhibitions to understand the exhibition of new sewage treatment technology, new technology, new equipment, and further communication.
the seminar was packed and warm.
as we all know, shenzhen qingquan is the standard drafting unit of "design rules of upward flow filter" in the national urban water supply and drainage industry, and has the top-notch technology of upward flow filter. dai explained the core technology of shenzhen qingquan - "sewage treatment plant upgrading limited tool - upward flow denitrification deep bed filter".
shenzhen qingquan dai explained the core technology "sewage treatment plant upgrading and upgrading of the sharp weapon - upflow denitrification deep bed filter"
dai explained that the upflow denitrification deep bed filter is a new and efficient denitrification deep bed filter process developed by qingquan company on the basis of the theory of reverse granularity filtration, absorbing the advantages of the overturned plate filter, non-blocking biological aerated filter and upflow filter, which is specially designed for upgrading sewage treatment plants. sharp weapon. the upward flow denitrification deep bed filter has the following technical characteristics:
1. good biological denitrification function tn< 5 mg/l;
2, good phosphorus removal function tp< 0.3 mg/l;
3. good suspended solids removal capacity ss < 5 mg/l and turbidity < 2 ntu;
4. no nitrogen drive device is needed.
5, no filter material loss;
6, the filtration cycle is longer (48h or above).
the filtration rate of shenzhen qingquan upflow denitrification deep bed filter is as high as 6~9m/h, which is much higher than that of general denitrification deep bed filter. water distribution and gas distribution system uses multi-functional filter tube or filter head used for up-flow filter to distribute water and gas, eliminating the traditional long-handled filter head and filter plate, not only distributes water evenly, but also solves the problem of easily blocked filter. upward flow denitrifying filter adopts "up spitting and down diarrhea" backwashing method, and the filter material is washed clean, so that the filtration cycle is longer and the effluent quality is better.
shenzhen qingquan dai explains the advantages of upward flow denitrification filter.
there are more than 100 application cases of upward flow filter in qingquan, shenzhen. dai summarized the application cases of upward flow filter and made more detailed explanations, such as meishan city sewage treatment plant in sichuan province, jiuquan sewage treatment plant in gansu province, national "ninth five-year" project demonstration project, and guxian sewage treatment plant in shanxi province. standard transformation project and so on. with the real and effective data display, it further proves that the shenzhen qingquan upflow filter technology is professional, efficient and feasible.
application case of upflow denitrification filter
shenzhen qingquan has got a good response in the technical seminar of upgrading and stabilizing the sewage treatment plant. through this technical exchange, the experts in the field have a deeper understanding and understanding of the application of shenzhen qingquan upflow denitrification filter, and hope to have further cooperation with shenzhen qingquan.
environmental protection construction is imperative. shenzhen qingquan is providing a land-saving, time-saving, labor-saving and money-saving industrial operation solution for the renovation of water supply and drainage systems in the world cities with strong technological innovation ability and diversified products. as the drafting unit of the national standard for the design rules of upward flow filter for urban water supply and drainage, it has been concentrating on the improvement of standards and capacity of urban sewage treatment plants, the increment of quality and quantity of water plants, the advanced treatment of industrial wastewater, the treatment of industrial aquaculture water, the reuse of reclaimed water and the intelligent modular water for 23 years. processing equipment. in the future, we will continue to make efforts to contribute to the construction and development of the world's environmental protection industry.
