| 摘 要： | 通过不同臭氧投加量对剩余污泥的破解试验,系统地研究了臭氧破解过程中剩余污泥基质和上清液中相关指标的变化规律。试验结果表明,臭氧破解能够有效减少污泥中固体物质的含量,在臭氧投加量为250 mg/g(O3/TS)的条件下,总残渣(TS)和挥发性固体(VS)分别减少了31.33%和35.59%;臭氧破解使得污泥上清液中的溶解性化学需氧量(SCOD)、总氮、总磷、氨氮含量均明显上升,pH值则呈下降趋势,但降幅不大。

| Abstract: | The sludge ozone disintegration experiment was carried out to examine changes in indexes for the supernatant and the substrate of sludge.The results showed that ozone could effectively disintegrate solid substances in sludge.Total solid(TS) and volatile solid(VS) were reduced by 31.33% and 35.59%,respectively,when the ozone dosage was 250 mg / g(O3/ TS).Due to ozone disintegration,the concentrations of SCOD,TN,TP and ammonia nitrogen in the sludge supernatant were significant increased and the pH value of sludge supernatant slightly decreased. |
