on december 14, 2018, the technical exchange meeting led by shenzhen qingquan water industry co., ltd. (hereinafter referred to as "shenzhen qingquan") was held in guangye group. mr. ye changming, chairman of shenzhen qingquan, was the keynote speaker of the meeting. the technical advantages and application prospects of abm combined process in sewage treatment bidding and expansion were discussed in depth with guangye group, and the sewage treatment office of the industry was also discussed. the advantages and disadvantages of scientific and technological means are compared.
at 3 p.m., the meeting officially began. minister yuan weifang, r&d department of guangye group, director wang yinsheng, operating center, and technical experts from the environmental protection institute, textile institute and metallurgical institute attended the meeting. minister yuan warmly welcomed the arrival of qingquan in shenzhen. mr. ye changming described the development process of shenzhen qingquan company in the past 23 years and the participatory process of upflow filter, and explained in detail the application of abm combined process developed independently.
shenzhen qingquan and guangye group technology exchange site
firstly, engineer wu bo of qingquan r&d department of shenzhen explained the current technical means of wastewater treatment in the industry, mainly focusing on the combination of shenzhen qingquan upflow denitrification deep bed filter and downflow denitrification deep bed filter, coagulation sedimentation tank, high efficiency sedimentation tank and filter cloth filter. shenzhen qingquan upflow denitrification deep bed filter has obvious advantages and amazing advantages. the effect of the treatment was admired by the experts on the spot.
upstream denitrification deep bed filter in qingquan, shenzhen vs downstream denitrification deep bed filter in a well-known foreign enterprise:
1. strong capacity of receiving pollutants, up to 15kg/m_;
2. multifunctional filter with uniform distribution of water and air.
3. there is no need for nitrogen displacement operation.
4. multifunctional filter with uniform distribution of water and air.
5. it can save 20-30% of carbon input.
6. backwashing cycle is long, usually 48-72 hours.

mr. ye changming explained that, compared with the current popular (aao mbr), abm combination process not only has superior performance, but also saves a large part of the investment operation and maintenance costs for users.
1. short running time: 8-12 hr, and no need to change the structure.
2. small area: 0.06~0.1m2/m3, 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.
in denitrification process, abm combined process 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 ability ss < 5 mg/l, turbidity < 2 ntu;
4. there is no need for nitrogen displacement device and no loss of filter material.
5. long filtration period (more than 48 hours);
6. reduction of carbon source dosage by more than 30% (denitrification).
mr. ye changming enumerated the application cases of abm combined process of shenzhen qingquan company, such as 40,000 m/d bid-raising and capacity-expanding project of a sewage treatment plant in linfen city, shanxi province, 30,000 m/d sewage treatment reconstruction and expansion project in moqi, inner mongolia, 80,000 m/d sewage treatment reconstruction and expansion project in jiujiang, jiangxi province, etc. the effluent quality can easily meet the first-class a standard (surface level iv), and the transformation of sewage treatment plant into a sewage treatment with low cost, low operation cost and stable effluent quality, field experts have indicated that upflow filter technology will become the mainstream technology in the new round of water treatment.
minister yuan launched a heated discussion with mr. ye changming on the technical application and prospect of upflow filter, and believed that abm combined process with superior performance should be more widely used in sewage treatment upgrading. at the same time, he suggested that shenzhen qingquan invite guangye group to visit shanwei east project as soon as possible, and make a comparison and selection on the ongoing projects in shanwei west area and shantou area. scheme.
shenzhen qingquan chairman and guangye field personnel launched a warm technical discussion
the technical exchange meeting between shenzhen qingquan and guangye group has been successful. the technical experts on the spot have highly recognized the application of the upflow filter and abm combined process of shenzhen qingquan in sewage treatment upgrading. it is of great value to promote the technological innovation and development of sewage treatment industry, and hope to have further cooperation with shenzhen qingquan.
only by seeking new ideas and exploring new methods can china's water treatment industry be further developed. founded in 1995, shenzhen qingquan has been devoted to the research and development and production of intelligent modular water treatment technology and equipment for 23 years. it has obtained dozens of patents in the field of filters and more than 500 successful projects. it is the standard drafting unit of "upward flow filter design rules" in the national urban water supply and drainage industry, the representative of non-membrane water treatment technology, and the leader of intelligent modular water treatment equipment. strong technical strength, continue to provide land-saving, time-saving, labor-saving and cost-saving industrial operation solutions for the upgrading and renovation of water supply and drainage systems in cities around the world.
