采用呼吸速率法评价臭氧氧化对酵母废水可生化性的改变。以最大呼吸速率、微生物累计耗氧量等作为评价指标进行了分析,结果表明,在臭氧投加量分别为50、200、300、400 mg/L下,废水中微生物的最大呼吸速率和累计耗氧量均较原水有所提高,微生物最大呼吸速率较原水分别提高了15.0%、44.7%、54.8%、98.3%,累计耗氧量分别提高了10.6%、23.0%、24.0%、10.1%。
採用呼吸速率法評價臭氧氧化對酵母廢水可生化性的改變。以最大呼吸速率、微生物纍計耗氧量等作為評價指標進行瞭分析,結果錶明,在臭氧投加量分彆為50、200、300、400 mg/L下,廢水中微生物的最大呼吸速率和纍計耗氧量均較原水有所提高,微生物最大呼吸速率較原水分彆提高瞭15.0%、44.7%、54.8%、98.3%,纍計耗氧量分彆提高瞭10.6%、23.0%、24.0%、10.1%。

Respiration rate has been used for evaluating the change in biodegradability of yeast wastewater after ozonation. It is analyzed by using maximum respiratory rates ,microbial accumulative oxygen consumptions ,etc. as evaluation indexes. The results show that, both of maximum respiratory rates and accumulative oxygen consumptions of microbes in wastewater are increased,when the dosages of ozone are 50,200,300,and 400 mg/L,respectively. The maximum respiratory rates of microbes can be increased by 15.0%,44.7%,54.8%and 98.3%,respectively. The accumulative oxygen consumptions are increased by 10.6%,23.0%,24.0%and 10.1%,respectively.
