september 3-6, 2018, china water supply and drainage magazine sponsored the 2018 china sewage treatment plant renovation advanced symposium (the second session) held in anhui province hefei binhu new area century jinyuan hotel. the conference attracted more than 1000 professionals to attend the meeting. the conference centers on the policy and market of upgrading the sewage treatment plant, comprehensive treatment of water environment and sewage recycling, discussion and application of core technology, and the latest project cases. through keynote speeches and technical discussions, the sewage treatment industry shows the most cutting-edge technical products and industry solutions.
symposium on sewage treatment upgrading
shenzhen qingquan water industry co., ltd. with the latest core sewage upgrading technology seminar, the chairman of the board - mr. ye changming to share for you - "up-flow filter in sewage treatment plant nitrogen and phosphorus removal application of the bid. upflow filter is a new filtration process based on the theory of "reverse granularity filtration" and modern flushing theory. it absorbs the advantages of v-type filter and flip-flop filter, and combines with flushing method, water distribution, gas distribution and automatic control technology. this process can help the sewage treatment plant to easily upgrade the first class b to the first class a. some enterprises, such as qingquan in shenzhen, have reached the surface standard iv. it is of great value to promote the technological innovation and development of the sewage treatment industry, and it is also a new starting point for the future of the sewage treatment industry.
shenzhen qingquan - mr. ye changming explained the application of core technology
in his speech, mr. ye changming said that the water quality after the traditional activated sludge treatment in the industry has not reached the national first-class a standard requirements, sewage treatment plant upgrading is imminent. then, in the case of a few unqualified indicators or water quality and quantity are not up to standard, in addition to the commonly used upgrading process, is there a more efficient solution? in this regard, shenzhen qingquan gave a new answer.
1. a few of the effluent indicators (tn/tp/ss) are not up to standard, through the shenzhen clear spring upward flow filter (mdf) for advanced treatment, all indicators are up to standard, and construction investment savings of 30% - 50%, operation cost savings of 30% - 40%.
2. in view of the situation that the water quality and water quantity are not up to the standard, the upflow filter combination process (abm) of shenzhen qingquan can be used to carry out the whole process transformation. this process does not need to change the original structure, save 40% of the area and reduce 50% of the operation and maintenance cost, while the water quality and water quantity meet the standard requirements.
the data show that compared with the traditional activated sludge process, the combined process of upward flow filter in shenzhen qingquan has obvious advantages.
mr. ye changming introduces the advantages of upflow filter technology.
mr. ye changming of qingquan, shenzhen, then introduced the abm technology scheme, which is based on the non-membrane technology developed by the upflow filter. as we all know, the traditional mbr membrane technology needs regular chemical cleaning in the use process, and it needs maintenance and replacement every 3-5 years, so mbr membrane technology has certain pollution and comparison. high operation and maintenance costs. by contrast, the abm technology scheme is fully functional and "natural pollution-free". the filter media in the filter need not be replaced for 10 years, no secondary pollution, and the operation and management is simple. the good result of abm technology scheme in water treatment has been highly recognized by the industry.
there are more than 100 successful application cases of upward flow filter in qingquan, shenzhen. the most notable thing is that this process can not only meet the current water quality standards, but also meet the requirements of the water quality standards which will be continuously improved in the future. mr. ye changming enumerated the application cases of meishan in sichuan province and jiuquan in gansu province. with the high quality and stable effluent water quality in the case, he left a deep impression on the professionals and expressed his optimism for the development prospects of the upward flow technology of qingquan in shenzhen.
mr. ye changming demonstrated the application of upflow filter technology.
industry insiders predict that in order to meet the existing and future national sewage treatment and discharge standards, the above-mentioned technology based on the flow filter will occupy a higher and higher proportion in this round of water treatment market, as a mature up-flow filter technology in shenzhen spring, in the future to promote the whole water treatment industry to be more efficient. the direction of high quality development plays a leading role.
