Research on Purifying Waste Gases Containing Volatile Organic Compounds in Low Concentration by Using Biochemical Method

Yang Xianwan,Sun Peishi,Huang Ruohua,Huang Bing,Chen Maosheng

Strategic Study of CAE 2001, Volume 3, Issue 9,   Pages 64-68

Abstract:

By means of lab test, enlarged test and industrial test of biopurifying the waste gas containing toluene (VOC) in low concentration, the biopurifying technology of organic waste gas was researched systematically. In a rubber-regeneration factory, the industrial test on purifying the low concentration organic waste gas (containing sulfur) from rubber-regeneration process by using biochemical method was carried through. For the waste gas containing toluene in a range of 300 〜1400 mg/m3, the industrial test device showed a good purification capacity. The result of 100 d test running with the device indicated that the purification efficiency of toluene in the rubber-regeneration waste gas could be kept at 90 % for a long time and the treated waste gas could be discharged in the situation of satisfying the National Emission Standard. The biopurifying technology of waste gas displayed its good advancement of technology and rationality of economy.

Effects of carrier-attached biofilm on oxygen transfer efficiency in a moving bed biofilm reactor

Yanling WEI,Xunfei YIN,Lu QI,Hongchen WANG,Yiwei GONG,Yaqian LUO

Frontiers of Environmental Science & Engineering 2016, Volume 10, Issue 3,   Pages 569-577 doi: 10.1007/s11783-015-0822-x

Abstract: Three laboratory-scale moving bed biofilm reactors (MBBR) with different carrier filling ratios rangingfrom 40% to 60% were used to study the effects of carrier-attached biofilm on oxygen transfer efficiencyThese results were compared to αSOTE of wastewater with a clean carrier (no biofilm attached).This indicated that the biofilm attached to the carrier had a negative effect on αSOTE.Biofilm flocs could decrease αSOTE by about 20%, and SMP could decrease αSOTE by 30%–50%.

Abstract:

MABR exhibits excellent TN removal performance for treating ROC with low C/N ratio.

Operating conditions should be properly controlled to achieve optimal TN removal.

Denitrifying bacteria and NOB are proved notably inhibited by high salinity stress.

The TN removal rate remains over 70% when the NaCl addition amount is below 20 g/L.
