with the grand opening of the 13th international symposium on water development in chinese cities and towns and the exposition of new technologies and equipment, the baf module (biological aerated filter module) displayed in qingquan, shenzhen, won the unanimous praise of users and colleagues. at the same time, mr. ye changming, chairman of the board of directors, appeared at the industry summit forum held at the same time to promote upflow filter technology. the application prospects provide strong theoretical basis and data support.
on november 30, 2018, mr. ye changming, chairman of qingquan, shenzhen, presented a seminar with the company's core technology, introduction and application of upward flow filter technology. the seminar enabled industry experts on the spot to understand the excellent performance and efficacy of upward flow filter in water treatment field, and provided practical information for the pain points and difficulties in water treatment. the solution is feasible.
speech by mr. ye changming, chairman of qingquan, shenzhen: "introduction and application of upward flow filter technology"
mr. ye changming said that the upflow filter is a new type of filtration technology based on the theory of "reverse granularity filtration" and modern flushing theory, which absorbs the advantages of v-type filter and flip-flop filter, and combines the innovative development of flushing method, water distribution and gas distribution and automatic control technology. it has the advantages of long filtration cycle, low flushing intensity, but thorough flushing. the features of less flushing water and higher automation represent the advanced level of modern particle filtration technology. contrary to the flow direction of the positive filter, the effect of "sedimentation and adsorption" of the upward flow filter is more significant, and the pollutant carrying capacity can reach 500% of the downward flow filter.
mr. ye changming introduced the technical characteristics of upflow denitrification deep bed filter
then, mr. ye changming explained the practical application process of upflow filter - abm combined process. abm is an organic combination of activated sludge method and biomembrane process for wastewater treatment. the scheme is composed of ao/aao bio-tank, baf module (biological aerated filter module), mdf module (multi-functional deep bed filter module). it is suitable for upgrading (expanding) or new construction of municipal sewage treatment plants.
compared with the current popular (aao mbr), abm combination process not only has superior performance, but also saves a large part of the cost of investment and operation for users.
1. short running time: 8-12 hr, and no need to change the structure.
2. small area: 0.06~0.1 m_/m_, saving more than 40% of the land;
3. maintenance cost is low: filter material is ceramsite or quartz sand, which is free of replacement for ten years, and operation and maintenance cost is reduced by 50%.
4. no secondary pollution.
5. automatic control, simple operation and management.

upward flow filter process is suitable for water quality improvement. the process can meet the current water quality standards, and also can be applied to the water quality standards which will be continuously improved in the future. mr. ye changming listed the new projects of shenzhen qingquan company hunan hengyang waterworks, the water supply project of villages and villages in huizhou city, guangdong province, the renovation and expansion project of hami no.3 waterworks in xinjiang, and the demonstration project of jiuquan sewage treatment plant in gansu province on the 9th five-year plan, etc. with the good operation effect of many projects, he gave the industry personages. i was deeply impressed.
at the end of the speech, ye changming shared with the experts of the field industry his career of more than 20 years. from the dilemma of product technology in china's water treatment industry at the beginning of reform and opening up, through more than 20 years of silent cultivation and hard research, qingquan in shenzhen has now proudly established itself in the world and led the innovation and development of new technologies. the common rise of water treatment enterprises in china to create a better future water world is also mr. ye changming's most proud wish.
mr. ye changming, chairman of qingquan, shenzhen, expressed his desire to be engaged in water treatment industry for more than 20 years.
shenzhen qingquan water industry co., ltd. was founded in 1995. it is the first batch of state high-tech enterprises in china's urban water supply and drainage industry founded in shenzhen in order to break the technological monopoly of foreign enterprises. its head office is located in shenzhen. since its inception 23 years ago, it has focused on providing solutions and intelligent modular water treatment equipment for the industry, such as upgrading and expansion of municipal wastewater treatment plants, increasing quality of water plants, advanced treatment of industrial wastewater, treatment of industrial aquaculture water, reclaimed water reuse and reclaimed water plants. shenzhen is the first batch of "national high-tech enterprises", the registered capital of the company is 31 million yuan, has passed the iso 9001 quality management system certification. shenzhen qingquan has been committed to technological research and development, for the development of china's sewage treatment industry to make water clearer, life more beautiful, is the firm mission of shenzhen qingquan!
