摘要
利用微泡技术实现污泥内组分释放和氧化,并利用臭氧氧化分离提取,基本消除了污泥恶臭。响应面法实验设计的优化条件如下:O3浓度为70%,反应釜压力0.3 MPa,保压时间为90 s,循环次数为5次。结果表明:该优化条件下,臭味强度降低5个等级,有机质含量由30%增至40%,水分降至65%~75%,除臭增有机质的效果较好。
In this paper,the microbubble technology was used in the sludge components release and oxidation,extraction by ozone oxidation to eliminate the stench of sludge. The experimental design of response surface method conditions was listed as follows: The concentration of O3 was 70%,the reactor pressure was 0. 3 MPa,the holding time was 90 s,and the number of cycles was 5. The results showed that: odor intensity decreased by 5 grades,the content of organic matter increased from 30%to 40%,the water dropped to 65% ~ 75%,and deodorizing increased organic matter better.
