摘要
采用HSB微生物菌种技术和缺氧-好氧组合工艺处理焦化废水。研究表明:该技术处理焦化废水有很好的效果,其中COD指标从3 000 mg/L左右降至150 mg/L以下,处理效率96.7%以上;NH3-N指标从500mg/L降至15 mg/L以下,处理效率97%以上;出水酚、氰、油等污染物均可达排放标准(GB8978-1996)。
This reseach adopts method of compounding special fungoid technique and technics treating coking polluted water, namely adopting HSB microbe fungoid technique and O- O/A compounding technics. This technology＇s appliance reseach indicate that adopting HSB microbe fungoid technique and O - O/A compounding technics have good effect on treating coking polluted water, the thickness of COD is put down from 3000 mg/L to 150 mg/L, disposal efficiency reaches 96.7% ; that of NH3 - N is cut down from 500mg/L to 15 mg/L, disposal efficiency exceedes 97% ; emission water indexes such hydroxybenzene, cyanogen and oil are up to emission standard.
