Abstract

一种废水压力厌氧生物处理的方法及其反应器装置,处理废水时,受螺旋导流腔螺旋升角的作用,延长了废水与颗粒污泥的接触时间,降低废水对颗粒污泥的剪切强度,使废水同颗粒污泥充分混合,废水中大部分有机物被转化成沼气。并利用了生物代谢时,所生成的代谢压力,在经由栅滤层时,悬浮固体被滤除掉,使出水水质达到一定纯度,使反应器的进水容积负荷率大幅度提高,同时所生成的沼气也具有一定的压力,为压力沼气。
The invention discloses a method for wastewater pressure anaerobic biological treatment and the reactor device. When treating wastewater, the wastewater-particle sludge contact time is prolonged and the wastewater to particle sludge shearing strength is decreased, which makes wastewater be mixed with particle sludge completely and large amount of organics convert to methane. Using pressure produced in biological metabolism, the suspension solid is filtered out at grid filtering layer, which make the quality of water outlet approach to definite purity, and the water inlet volume load factor of the reactor being improved substantially. And the produced methane also has definite pressure, being pressure methane.
