摘要
通过对矿化垃圾生物反应器处理焦化废水的研究,以穿透曲线为理论依据,确定了反应床的设计方案,采取以海绵作为生物反应床的隔层,很好地解决废水贴壁短路的现象,提高了单位矿化垃圾的吸附量。同时对不同温度、不同CODCr浓度以及不同进料量进行了优化。微生物的降解能力在30℃时更理想,且矿化垃圾对氨氮的吸附能力远远好于CODCr,微生物生长所需要的最适pH值为7.5。高浓度CODCr对微生物的抑制作用导致生物降解能力小于矿化垃圾反应床的吸附能力。
The treatment of coke-plant wastewater using aged-refuse-based bioreactor was investigated. The design proposal of bioreactor, based theoretically on breakthrough curve, was determined. Solving the short circuit well, sponge was selected as interlayer of bioreactor, which can enhance adsorption quantity of unit age-refuse. Meanwhile, the optimization of different temperature,COD_ Cr and quantity of fluid was carried out. Bio-degradability of microorganism is better at 30 ℃, age-refuse has much stronger adsorption to NH_3-N than to COD_ Cr ; the best pH for microorganism growth is 7.5. Due to the inhibition of high-concentration COD_ Cr , bio-degradability of microorganism was less than adsorption quantity of age-refuse.
