【技术实现步骤摘要】
循环式除氨塔
本技术属于氨氮废水处理
,尤其涉及一种循环式除氨塔。
技术介绍
目前,现有除氨塔的除氨原理之一是采用空塔吹脱的办法来进行除氨的。空塔的特点是除氨效率与分散度成正比,分散度越高,一次脱氨效率越好;其缺点是分散度越高,分散器越容易堵塞,所以在保证分散器三个月内不堵、只能用氢氧化钠调pH的情况下,其一次除氨效率最高不会超过85%,如果用氧化钙调pH,一次除氨效率最高不会超过70%。可见现在的除氨塔除氨效率不高,还存在着较大的提升空间。并且现有的除氨塔由于受到后续处理效率的限制,对于进水量的调控存在局限性。
技术实现思路
本技术的目的在于克服上述技术不足,提出一种循环式除氨塔,解决现有技术中除氨效率不高,人为调控除氨效率受限的技术问题。为了达到上述技术目的,本技术实施例提供了一种循环式除氨塔,该循环式除氨塔包括:塔体,塔体为中空柱状结构,内部设置有多段除氨段,每段除氨段包括一个分散器和一个布风板,布风板设置于分散器下方,塔体的顶部设置有出风管,底部设置有出水管,在出水管的上方设置有进风管,塔体的侧面还设置有进水管,进水管与最上方的分散器连通;循环管,循环管上端 ...
