废水处理一体化生物反应器的发展

Development of Integrated Bioreactors for Wastewater Treatment

废水处理的一体化生物反应器由于具有投资少、占地小、管理运行方便等特点备受青睐.较早的有一体化氧化沟、SBR反应器、一体式膜生物反应器等.随着一体化反应器的发展,生物膜法被结合起来作为主体工艺,另外好氧工艺也与厌氧/缺氧工艺结合起来,出现了很多系统有机负荷更高、抗冲击能力更强、脱氮除磷效果更好的新式一体化反应器,如AmOn一体化生物反应器、五箱一体化反应池、一体化生物转筒反应器IBDR、A/O一体式曝气生物滤池等.一体化生物反应器的发展适应我国国情,具有广阔的应用和发展前景.

The integrated bioreactors for wastewater treatment have attracted people＇s great attention because they need small investment and small area of land with convenient management and easy operation. The early ones include the integrated oxidation ditch, sequencing batch reactor and submerged membrane bioreaetor. With the development of the integrated bioreactors, bio-film process is combined as the main process, aerobic process is combined with anaerobic/anoxic process, and more novel integrated bioreactors appear with higher organic load in system, better capacity for shock loading resistant, and better denitrification effect and phosphorus removal, such as AmOn integrated bioreactor, five-box integrated tank, integrated biological drum reactor and A/O integrated biological filter. The development of the integrated bioreactors is suited to the situation of China, and they can be widely applied and utilized in many fields.
