复吹转炉“留渣 双渣”脱磷工艺试验

摘要：在国内某转炉钢厂采用“留渣 双渣”工艺技术进行脱磷工艺试验。结果表明：随着转炉前期脱磷率不断升高,终点脱磷率不断提高。铁水硅含量对前期脱磷率的影响最大。根据铁水成分,在冶炼前期适当降低供氧强度、降低气固氧比、加入适量石灰及烧结矿,均有利于前期脱磷率的提高。在一倒时每吨钢液加入4~8kg石灰,不影响出钢温度,可提高一倒-终点阶段脱磷率,同时可提高终点脱磷率。从终点的控制效果可知,终点炉渣碱度应保持不小于3.0,炉渣中FeO质量分数在16%~20%,并适当降低终点出钢温度在1610~1630℃,有利于终点脱磷率的提高。通过加强熔池搅拌,促进钢渣反应趋于平衡,有利于终点磷分配比提高,从而可进一步提高终点脱磷率。

Effects Of Ozone On The Production Of Biodegradable Dissolved Organic Carbon (BDOC) During Water Treatment

This article deals with the oxidation effect of ozone on the increasing fraction of biodegradable organic matter with the “ozotest” method, a laboratory technique which simulates the effect of ozonation and allows a complete oxidation assessment. Ozone treatment was performed on river water samples and sand filter effluent samples. Ozone consumption, reduction of UV absorbance and BDOC formation were monitored with applied ozone doses from 0 to 10 mg/L and with contact times from 0 to 60 min. The BDOC formation was optimum at an applied ozone dose of 0.25-0.5 mg O₃ per mg DOC (contact time = 5 min) corresponding to apparition of traces of residual ozone and maximum UV reduction. Maximum ozone consumption, UV reduction and BDOC formation occurred simultaneously during the first two minutes of treatment. Concerning BDOC formation, applied ozone dose showed a greater effectiveness than contact time. For the same quantity of consumed ozone, a short contact time associated with a high ozone dose was preferable to a long contact time and a low ozone dose.     

Experiences with Ozone Treatment Of Drinking Water in Yugoslavia

Ozone currently is being used in several drinking water treatment plants in Yugoslavia. The new Belgrade water treatment plant “Makis” is the largest one with 42 kg/h of installed ozone generating capacity and has been in operation since 1987. This paper describes the main features of ozone application in drinking water treatment. The experimental results of “Makis” pilot-plant investigations and a few examples of ozone application in Yugoslavia are presented.
