- 摘要:
- 為了比較具有不同密度和孔隙率的A、B兩種填料在移動(dòng)床生物膜反應(yīng)器（MBBR）中處理廢水的能力，采用R1、R2兩個(gè)反應(yīng)器分別裝填兩種填料，并對(duì)其水質(zhì)指標(biāo)、生物膜表觀形貌、生理生化特征進(jìn)行對(duì)比研究。結(jié)果表明，填充填料A的R1反應(yīng)器的適應(yīng)性、抗沖擊性以及掛膜啟動(dòng)期出水水質(zhì)均優(yōu)于填充填料B的R2反應(yīng)器；R1生物膜的厚度、粘附力與生物膜更新速度均高于R2，其脫氫酶活性顯著高于R2，即孔隙率較高、相對(duì)密度更接近于1的填料應(yīng)用于移動(dòng)床生物膜反應(yīng)器的效果更佳。
- Abstract:
- In order to compare the ability of two kinds of bio carriers A and B with different density and porosity to treat wastewater in moving bed biofilm reactors(MBBR), two MBBRs, R1 and R2 filled with carriers A and B respectively, were used to compare their effluent quality indexes, biofilm morphology, physiological and biochemical characteristics. The results showed that the adaptability, impact resistance and the effluent quality during startup phase of reactor R1 were better than those of reactor R2. The thickness, adhesion and renewal rate of R1 biofilm were higher than R2. The activity of dehydrogenase in reactor R1 was also significantly higher than reactor R2. That is to say, a carrier with a higher porosity and the relative density closer to 1 has a better effect when applied to the moving bed biofilm reactor.
