The State Water Special Administration Office (hereinafter referred to as "Water Special Project") convened a live meeting of the promotion of rural wastewater treatment technologies in major projects of water pollution control and treatment in Jiangxi Province. A new technology called "FMBR and Oxygen Membrane Bioreactor" (hereinafter referred to as FMBR technology) attracted great interest of delegates and local authorities.
At present, China's rural sewage treatment is still faced with many problems, sludge, water is difficult to achieve a stable standard and other issues have constrained the development of rural sewage treatment industry. Faced with the dilemma, the water set up a special project entitled "R & D and industrialization of the non-point source pollution treatment facilities in the drainage basin" and developed the FMBR technology. The breakthrough was made in "Near Zero Emission of Organic Sludge, Removal of Phosphorus from Wastewater and C, N, P synchronous removal in a single control "three major technical problems, to achieve efficient sewage treatment; developed a" remote monitoring + mobile 4S station "management mode, the use of Internet technology to achieve remote monitoring of sewage treatment facilities and automatic fault alarm, in the absence of Under the condition of being on duty, the sewage treatment facilities are efficiently and precisely managed. Compared with the international conventional technologies, the control procedures are simplified from 6 to 1, the land occupation is reduced by more than 50%, and the discharge of sludge is reduced by more than 95% Water quality up to a stable A standard.
FMBR technology in Huichang City, Jiangxi Province Sewage Treatment Plant Phase II project has been applied, the processing scale of 10,000 tons / day. In sharp contrast with the first phase of the traditional process with a processing capacity of 10,000 t / d, the construction period is greatly shortened, and the construction period of the new FMBR model is reduced from 18 months to 6 months. The construction period Shorten the 2/3; two is the land area is greatly reduced, the construction land from the original 35 acres reduced to 5 acres, covering only 1/7 of the traditional process; third is sludge reduction, the traditional process mud volume 10 Ton / day, and now achieve more than 95% reduction of sludge; Fourth, manpower is greatly saved, the traditional process operation and maintenance needs 28 people, now only two people, to achieve more than 90% of manpower savings.
At present, the sewage treatment plant has operated for nearly half a year with nearly zero discharge of organic sludge, and the treated effluent has reached the Grade A standard of "Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants" and the effect is good. This technology has been extended to 29 provinces (cities) across the country, especially in key projects such as non-point source management in Erhai Lake, black-odor water treatment in Dalian city and sewage treatment in the top 100 center towns in Jiangxi Province.
