摘要
试验研究了间歇曝气法处理青霉素废水过程中pH值、处理周期、温度、冲击负荷对处理效果的影响。该法中的兼氧及好氧菌能在不需对青霉素废水中的SO42-和"1231"进行物化预处理的前提下有效地降解废水中的有机物。进水COD浓度可达10 000 mg/l,COD去除率在85%以上,投配负荷达7 kgCOD/m3.d,最大冲击负荷达14 kgCOD/m3.d。青霉素废水中"1231"产生的泡沫不会影响SBR处理装置的正常运行。在曝气过程中泡沫可自行消失。"1231"去除率高达97%以上。提出间歇曝气法是处理青霉素废水一条较理想的途径。
The experimental study was conducted on affecting factors during the treatment of penicillin wastewater by using intermittent aeration method, including pH value, processing cycle, temperature and impact load. The facultative anaerobes and aerobes can effectively degrade organic in the penicillin wastewater without physicoehemical pretreatment of SO4^2- and ＂1231＂ COD of inflow is up to 10 000 mg/L, and its removal ratios is higher than 85% , the load capacity is up to 7 kgCOD/m^3·d, and the max impact load is 14 kgCOD/m^3·d. The foam that is produced by ＂1231＂ in the penicillin wastewater have no effect to on SBR. In the process of aeration, the foam could disappear automatically. The removal ratio of ＂1231＂ is up to 97%. It is advanced that the intermittent aeration method is an ideal way in treating penicillin wastewater.
