新型气化炉煤气洗涤废水生物脱氮的研究

Research on biological denitrification for scrubbing water from new type of gasifier

在实验室,采用SBR生化反应器,分别研究了经空气吹脱预处理和未经预处理的新型气化炉煤气洗涤废水经驯化建立的生态系统脱除氨态氮和COD以及脱氮模式的区别,得出以下结论:新型气化炉煤气洗涤废水可采用短程亚硝化型硝化形式直接进行生化处理。

<Abstrcat> Research was made on ammonium nitrogen and COD removal in waste water, pretreated by air-blowing and nonpretreated, both came from scrubbing of gas produced by new type of gasifier, by means of cultivating biological system in SBR biological reactor. By comparison it came to the conclusion that the scrubbing water could be treated directly by biochemical process with short-range nitroso-nitrification.
