摘要

摘要:
食用菌湿法堆垛育菇废水作为一种高浓度有机废水，具有难降解、高COD和高氨氮的特点，利用常规处理工艺难以实现达标排放。采用气浮-折流A/O生物膜反应器(HAOBR)-O₃/H₂O₂组合工艺，研究气浮-HAOBR对育菇废水中COD和氨氮的处理效果，探讨O₃/H₂O₂催化氧化段在不同组合方式下的处理效果和最佳控制参数，并利用三维荧光光谱技术分析该组合工艺废水中溶解性有机物（DOM）的变化特性。结果表明：经气浮-HAOBR处理后，育菇废水中COD和氨氮浓度分别降至（485±25）和（1.32±0.11） mg/L；在O₃和H₂O₂浓度分别为0.88和333 mg/L时，O₃/H₂O₂单元对COD和氨氮的去除效果最佳；最终出水COD和氨氮浓度分别为（22.50±1.50）和（1.30±0.15） mg/L，平均去除率分别为99.40%和98.70%；育菇废水中DOM主要是类富里酸物质、溶解性微生物代谢产物和类腐殖酸物质，处理后DOM荧光强度大幅降低，但主要组分未发生改变。气浮-HAOBR-O₃/H₂O₂组合工艺能有效去除育菇废水中COD、氨氮和DOM，出水满足GB 8978—1996《污水综合排放标准》一级标准，具有很好的应用前景。

Abstract:
As a kind of high concentration organic wastewater, the wet stacking wastewater from the edible mushroom breeding is hard to be degraded with dense COD and ammonia nitrogen. It poses a challenge to make the discharge reach the standard just using conventional treatment processes.The combined process of Air Floatation-Baffled A/O Biofilm Reactor (HAOBR)-O₃/H₂O₂ was adopted to study the treatment effect of Air Floatation-HAOBR on COD and ammonia nitrogen in mushroom breeding wastewater, to discuss the treatment effect and optimal control parameters of O₃/H₂O₂ catalytic oxidation section under different combination modes. Three-dimensional fluorescence spectroscopy was employed to analyze the variation of dissolved organic matter (DOM) in the wastewater in this combined process. The results showed that the concentration of COD and ammonia nitrogen in the mushroom wastewater decreased to (485±25) and (1.32±0.11) mg/L respectively after the treatment of Air Flotation-HAOBR; when the dosage of O₃ and H₂O₂ was 0.88 and 333 mg/L respectively; the final effluent COD and ammonia nitrogen concentrations were (22.50±1.50) and (1.30±0.15) mg/L respectively, and the average removal rates were 99.40% and 98.70% respectively. It was assayed that fulvic acid-like substances, soluble microbial metabolites and humic acid-like substances were the dominant DOMs in mushroom breeding wastewater. After the treatment, the fluorescence intensity of DOM was greatly reduced, but the major components remained unchanged. The combined process could effectively remove COD, ammonia nitrogen and DOM in mushroom breeding wastewater, and the effluent could meet the first level discharge standard of Integrated Wastewater Discharge Standard (GB 8978-1996), with a good prospect for the treatment of mushroom breeding wastewater.
