- 摘要:
- 純膜MBBR工藝系統(tǒng)不設(shè)二沉池，無(wú)污泥回流，以附著態(tài)形式存在的懸浮載體生物膜完成污染物的去除，生物膜在流化的作用下實(shí)現(xiàn)動(dòng)態(tài)更新，無(wú)需反沖洗，具備極佳的抗低溫性能，處理負(fù)荷高，停留時(shí)間短，可靈活應(yīng)用于污水廠各工藝段，從而獲得優(yōu)良的出水水質(zhì)。總結(jié)了純膜MBBR工藝污染物的去除特性，描述了該工藝脫碳、硝化和反硝化過(guò)程。介紹了國(guó)外Lillehammer、Gardermoen、Sjolunda、Phillips Petroleum Borger、TAU污水廠純膜MBBR工藝的設(shè)計(jì)和應(yīng)用情況，回顧了國(guó)內(nèi)純膜MBBR工藝在微污染水、工業(yè)廢水、市政污水、高氨氮廢水處理中的應(yīng)用情況。實(shí)踐應(yīng)用表明，純膜MBBR工藝結(jié)合更加緊湊的深度處理工藝，最大可節(jié)約80%的占地，去除負(fù)荷高，工藝流程短，具有占地省、投資低、運(yùn)行簡(jiǎn)便等優(yōu)勢(shì)，適用于污水廠新建以及擴(kuò)容提標(biāo)，具有極大的發(fā)展空間和廣泛的應(yīng)用前景。
- Abstract:
- There is no secondary sedimentation tank and sludge return system in the pure MBBR process.The pollutants can be removed effectively by biofilm which attached to the suspended carriers. The biofilm can be dynamically renewed by fluidization without backwashing. The pure MBBR process has excellent advantages, such as low temperature resistance, high removal loading, short retention time, flexibility application to the many sections of WWTP, so as to obtain excellent effluent quality. In this paper, the characteristics of removal pollutants in pure MBBR process are summarized, and the decarbonization, nitrification and denitrification processes are described as well. The design and application of pure MBBR process in Lillehammer WWTP, Gardermoen WWTP, Sjolunda WWTP, Phillips Petroleum Borger WWTP, and TAU WWTP which are located abroad are introduced. The application of pure MBBR process in micropolluted water, industrial wastewater, municipal wastewater and high ammonia nitrogen wastewater in China are reviewed. Practical application shows that the pure MBBR process combined with a more compact advanced treatment process can save up to 80% of the land occupation compared with the conventional process. The pure MBBR process has the advantages of high removal loading, short process flow, low land occupation, low investment and simple operation. It is suitable for new construction and expansion of WWTP, and has great development space and wide application prospect.
