from september 19 to 20, 2018, three symposiums on the upgrading and renovation of sewage treatment in upflow filters, led by qingquan, shenzhen, were held in hunan water resources and hydropower survey and design institute, hunan architectural design institute municipal branch and hunan chemical and pharmaceutical design institute. as the main speaker, mr. zheng zhichao, the assistant general manager of qingquan in shenzhen, discussed the application of the upflow filter in sewage treatment upgrading (expansion) with the experts on the spot, and exchanged in depth on the existing problems of sewage upgrading in shenzhen.
on the morning of september 19, shenzhen general assistant zheng and his delegation arrived at hunan research institute of water conservancy and hydropower survey and design. as a representative of the design institute, president zhang welcomed the arrival of general assistant zheng and his delegation. in this exchange, the experts on the spot have a deeper understanding of the upward flow filter technology of shenzhen qingquan. president zhang is very interested in the modular products of qingquan in shenzhen. during the exchange process, he inquired about the advantages and costs of intelligent modular water treatment equipment. in this regard, zheng zhuzhu has made a detailed answer one by one, and enumerated the shenzhen pine river and other water treatment projects successful cases. president zhang said that under the current tight construction period and high requirements of water treatment environment, the modular water treatment equipment in qingquan, shenzhen, will be in line with the future development trend, the application prospect will be very broad.
after the exchange in hunan water conservancy and hydropower institute, at 2:00 p.m., mr. zheng and his party arrived at the municipal branch of hunan architectural design institute. mr. liu was in charge of the exchange and warmly welcomed mr. zheng and his colleagues from qingquan, shenzhen. zheng zhongzhu introduced shenzhen qingquan company and patent in detail, and gave a detailed answer to the technical experts of hunan architectural design institute municipal branch. the whole exchange mainly centered on the technological basis and application prospects of upflow filter. in view of liu's doubts about the superiority of upstream flow filter, zheng explained that since the upstream flow filter adopts the "up-spit and down-drain" backwashing method, there is no problem of gas blockage compared with the forward flow filter, thus achieving a longer filtration period and better effluent quality.
on the morning of september 20, the exchange meeting between qingquan in shenzhen and hunan provincial institute of chemical and pharmaceutical design was held as scheduled. mr. zheng introduced the principle and advantages of the upward flow filter technology of shenzhen qingquan to the experts on the spot. the experts raised many questions about the water distribution and air distribution system of the upward flow filter, the plugging of the filter head and the filling of the filter. the exchange atmosphere was very warm. mr. zheng answered the experts'questions in detail, and combined with the company's successful cases, analyzed and explained the reliability and stability of the company's upflow filter technology. on-site experts nodded frequently, expressing their deep recognition of the upward flow technology of qingquan in shenzhen, and discussing the scheme design combined with the specific projects of the design institute.
the three exchanges were successful. the technical experts present said that through this exchange, they had a deeper understanding and understanding of the application technology of shenzhen qingquan upflow filter in sewage upgrading, and hoped to have further cooperation with shenzhen qingquan.
as the standard drafting unit of "design rules for upward flow filters" for urban water supply and drainage in china, shenzhen qingquan has attached great importance to technical research and development since its inception. at present, it has obtained dozens of patents on upward flow filters, non-blocking aerated biological filters and other filters. the company operates in more than 30 provinces and cities throughout the country and successfully implements more than 500 projects. it provides land-saving, time-saving, labor-saving and money-saving industrial operation solutions for the renovation of water supply and drainage systems in cities around the world, and strives to create "intelligent modular water treatment equipment and solution leader".
