- 摘要:
- 针对四川某公司采用酮连氮法合成水合肼生产废水中污染物种类特殊、生物毒性强、处理难度大的情况，采用“Hi-SOT氧化塔+水解酸化+A/O+二沉池”工艺进行中试，考察了该废水的进水水质情况、Hi-SOT氧化塔中mO3 ∶mCOD的投加比、水解酸化池微生物毒性耐受程度以及中试系统的整体运行情况。结果表明，经过6个多月的连续运行，中试系统的运行情况良好，出水COD和NH3-N分别稳定在50和5 mg/L以下，去除率分别达到94%和98.7%。
- Abstract:
- The wastewater from synthesis of hydrazine hydrate by keto hydrazine method in a company in Sichuan Province has the problems of containing special types of pollutants, strong biological toxicity and difficult to treat.A pilot-scale test with treatment process of “Hi-SOT oxidation tower + hydrolytic acidification + A/O+sedimentation tank” was carried out to investigate the quality of the wastewater, dosage ratio of O3 and COD in the Hi-SOT oxidation tower, tolerance of microbe to toxicity in the hydrolytic acidification tank and overall performance of the pilot system. The results showed that good performance of the pilot system was achieved after more than six months of continuous operation. COD and NH3-N in the effluent were always less than 50 mg/L and 5 mg/L, respectively, and the removal efficiencies were 94% and 98.7%.
