BAF属第三代生物膜反应器,不仅具有生物膜工艺技术的优势,同时也起着有效的空间过滤作用。通过使用特殊的滤料和正确的配气设计,BAF具有以下工艺优点:
(1)、采用气水平行上向流,使得气、水进行极好的均匀,防止了气泡在滤料层中凝结和气堵现象,氧的利用率高,能耗低;
(2)、与下向流过滤相反,上向流过滤持续在整个滤池高度上提供正压条件,可以更好地避免形成沟流或短流,从而避免通过形成沟流来影响过滤工艺而形成的气阱;
(3)、上向流形成了对工艺有好处的半助推条件,即使采用高过滤速度和负荷,仍能保证BAF工艺的持久稳定性和有效性;
(4)、采用气水平行上向流,使空间过滤能被更好的运用,空气能将固体物质带入滤床深处,在滤池中能得到高负荷、均匀的固体物质,从而延长了反冲洗周期,减少清洗时间和清洗时用的水、气量。
(5)、滤料层对气泡的切割作用使气泡在滤池中的停留时间延长,提高了氧的利用率。
(6)、由于滤池极好的截污能力,使得BAF后面不需再设二沉池。
BAF可广泛用于水体富营养化、生物污水、市政污水、生活杂排水、食品加工、酿造、化工、制药、印染、焦化等废水处理。

Through the use of special media and the right valve design, BAF technology has the following advantages:
(1), the level of use of gas flow to the line, making gas, water uniformly excellent, to prevent a bubble in the media layer of condensation and gas block, the utilization of high-oxygen, low energy consumption;
(2), and contrary to the flow filtration, filtration continued to flow across the filter to provide a high degree of positive pressure, better to avoid the formation of short-ditch or stream flow, so as to avoid the formation of channel flow through the filter to influence the process and The formation of the gas well;
(3), to form a stream of technology-propelled semi-good condition, even if the filter for high speed and load, the BAF process can ensure the lasting stability and effectiveness;
(4), the level of use of gas flow to the line so that space can be filtered better use of solid matter into the air to deep-bed filter, filter can be in th
