【摘要】:采用多孔孔板空化反應(yīng)器處理石油污水,考察了不同入口壓力、石油初始含量、溫度和空化時(shí)間等影響因素對(duì)水中石油污染物去除效果的影響。結(jié)果表明,當(dāng)入口壓力為0.30 MPa、溫度為35℃、空化時(shí)間為5 h時(shí),水力空化對(duì)質(zhì)量濃度為90 mg/L的石油污水中石油污染物的去除率可達(dá)57.68%。氣相色譜-質(zhì)譜聯(lián)用儀分析結(jié)果顯示,空化反應(yīng)5 h后,譜峰數(shù)量由原水的25個(gè)減少到14個(gè),烷烴占有機(jī)物總量由42.37%減少到28.45%,峰面積也由49.36%減少到35.49%。這說(shuō)明水力空化對(duì)水中石油污染物有很好的降解和去除作用。
[Abstract]:The effect of different inlet pressure, initial oil content, temperature and cavitation time on the removal efficiency of petroleum pollutants in water was investigated by using porous plate cavitation reactor. The results show that when the inlet pressure is 0.30 MPa, the temperature is 35 鈩,
