摘要

试验测定了0~5 m in、0~30 m in两个时间序列

0.03 W/mL、0.05 W/mL和0.1 W/mL三个能量水平超声波作用对剩余污泥的摄氧速率(OUR)、溶解性COD(SCOD)、溶解性总氮(TN)和总磷(TP)的变化。结果表明

低强度超声波对污泥作用分为两个阶段:第一个阶段发生在0~4 m in

主要是作用在污泥絮体层面

表现为污泥絮体中SCOD、TN和TP溶出;第二个阶段对污泥生物体产生影响

微生物活性加强

OUR、TN和TP都有较大增长。

Abstract

In this study the influence of the low-intensity ultrasound treatment on excess sludge has been observed.The oxygen uptake rate(OUR)

soluble chemical oxygen demand(SCOD)

soluble total nitrogen(TN) and soluble total phosphorus(TP) were examined for three power levels of 0.03 W/mL

0.05 W/mL and 0.1 W/mL as well as two time series of 0~5 min and 0~30 min.It showed that there were two stages of ultrasonic treatment: the first stage took place within the flocs in four minutes

in which SCOD

TP were dissolved from flocs.In the second stage

the microbial activities have been strengthened

as well as OUR

TP have increased greatly.
