introduction: from august 27 to 30, 2019, the 2009 china sewage treatment plant advanced symposium (the third session) sponsored by china water supply and drainage magazine was grandly held in ningbo pan-pacific hotel. this conference is a very influential and professional event in the water treatment industry. it attracted more than 1500 professionals, including well-known experts, scholars and representatives of mainstream units, from various research directions of sewage treatment bidding and transformation. on the spot, a heated discussion was carried out on the two themes of improving the quality and efficiency of sewage treatment plants and improving the drainage pipe network. through field technology and case sharing, the most advanced technology products and industry solutions were provided for the sewage treatment industry.
mr. ye changming, chairman of shenzhen qingquan water industry co., ltd., was invited to attend the advanced seminar on the upgrading of water supply and drainage wastewater treatment plants in china. at the seminar, he gave a special report on the application of upflow filters and modular equipment in improving the quality and efficiency of wastewater treatment plants. before the speech officially began, president ye changming successfully attracted the attention of the guests on the spot with the company's corporate promotional film as the starting point. next, mr. ye changming, with the theme of "original intention, teacher worship, innovation, confusion, persistence, achievement, goal and mission", describes the 24-year journey of qingquan in shenzhen. at the meeting, mr. ye changming focused on the innovation and achievements of shenzhen qingquan in the field of upflow filter.
mr. ye changming introduced that the upflow filter is based on the theory of counter-granularity filtration, which absorbs the advantages of v-type filter and flip-flop filter, and has invented its water distribution system, air-water flushing mode and tank structure. at the same time, it has developed key process equipment and automatic control system, and then developed a new type of filter. leading filter technology. after more than 20 years of continuous research and in-depth exploration, shenzhen qingquan has obtained dozens of invention patents and software 飞禽走兽游戏机 copyright, and upflow filter has won the national key new product certification. the national urban water supply and drainage design regulations for upward flow filters, co-edited by shenzhen qingquan and zhongnan municipal college, was formally implemented on january 1, 2017. in november 2018, shenzhen qingquan academician workstation was officially established, which will greatly promote the development process of intelligent control system technology for large-scale water treatment equipment in shenzhen. in the future, the application of water treatment equipment can greatly reduce the labor intensity of workers and improve the management level of water treatment facilities.
at present, the performance of qingquan in shenzhen has spread over more than 30 provinces, and there are more than 300 successful cases. mr. ye changming highlighted the case of shenzhen qingquan's proposal for shenzhen henggang sewage treatment plant (100,000 tons per day) and the reclaimed water utilization project (200,000 tons per day) in urumqi, xinjiang. the upstream denitrification mdf module of shenzhen qingquan is used in shenzhen henggang sewage treatment plant. the quality of effluent is better than surface quasi-v. it is worth mentioning that shenzhen henggang project has only 26 days'construction period from the commissioning of the equipment to the discharge of water. it is the first successful application of the intelligent modular water treatment equipment in large-scale sewage treatment plants in shenzhen qingquan. upstream denitrification deep bed filter of shenzhen qingquan is used in the reuse project of reclaimed water in urumqi, xinjiang. it is mainly used to remove tn, tp and s s.
upward flow filter is used as denitrification deep bed filter without setting up high-efficiency sedimentation tank. its tn removal capacity is up to 25mg/l, which is much higher than that of international well-known counterparts (7mg/l), and it is in the absolute leading position. upflow filter has attracted many professionals because of its unique water inflow mode and excellent nitrogen and phosphorus removal performance. after the speech, many professionals came to the company booth for consultation. in response to various questions raised by the designer, mr. ye changming patiently answered them, and the designer on the spot nodded frequently, expressing deep admiration for mr. ye changming's professionalism and technological advancement.
the upflow filter technology of qingquan in shenzhen can not only easily upgrade the water quality of sewage treatment plant from grade b to grade a, but also adapt to the continuous improvement of water quality standards and achieve the effluent quality reaching grade iv of the surface standard. during the 24-year journey, we have reason to believe that where there is water pollution, there are clear springs. let's move forward hand in hand, let's make the water clearer and the life more beautiful!
