摘要:实验研究发现,在碱性环境中臭氧破解污泥的效果下降;将污泥pH调至11,24 h后,MLSS减少率=38.3%、MLVSS减少率=45.1%;通入臭氧18 m in后,MLSS减少率=18.3%、MLVSS减少率=27.2%;污泥减量过程中pH呈下降趋势。
The experimental indicated that ozone used to treat sludge achieved bad results in the alkaline environment; Adjust sludge's pH to 11, after 24h, MLSSreduction rate =38.3% 、MLVSSreduction rate =45.1% ;When the oxidation time was 18 min, MLSSreduction rate = 18.3% 、MLVSSreduction rate =27.2% ; and the pH was decreased in the sludge reduction process.
