摘要

家禽加工废水(PPW)是一种富含营养物质的废水,具有再用于作物灌溉的潜力。本研究利用一个连续运行 222 天的中试规模 "家禽生态学 "系统,对将 PPW 转化为水培营养液进行了调查。该系统每天处理 57 升 PPW,由生物反应器(接种微藻和硝化细菌)、澄清器、膜过滤器、紫外线消毒装置和深水水栽系统组成。对该系统的氮转化、有机物去除效率和病原体水平进行了评估。虽然所有生物反应器的可溶性有机物去除率(sCOD)都很高(80%),但由于有机物负荷高(350-800 毫克 sCOD L-1)、停留时间相对较短(24 小时)以及溶解氧水平低(3.5 毫克 O2 L-1),硝化作用受到了限制。生长床出现了明显的硝化现象,表明上游有机物去除的重要性。在生物反应器中补充二氧化碳(0.5% v/v)并不能促进生物反应器中的硝化作用,但由于调节 pH 值的作用,有利于生长床中的硝化作用。微生物分析表明,紫外线处理后,生物反应器中未检测到沙门氏菌,总大肠菌群(∼40%)和需氧菌落总数(∼30%)大幅减少。这些研究结果表明,富含营养物质的工业废水可持续、安全地再用于农业。

Pilot-Scale Evaluation of Poultryponics: Insights into Nitrogen Utilization and Food Pathogen Dynamics

Poultry processing wastewater (PPW) is a nutrient-rich effluent with the potential for reuse in crop irrigation. This study investigated transforming PPW into a hydroponic nutrient solution using a pilot scale “poultryponics” system operated continuously for 222 days. The system treated ∼57 L d–1 of real PPW and consisted of bioreactors (inoculated with a consortium of microalgae and nitrifying bacteria), clarifiers, membrane filters, a UV disinfection unit, and a deep-water hydroponic system. The system was evaluated in terms of nitrogen transformation, organic removal efficiency, and pathogen levels. Although soluble organic removal efficiencies (sCOD) were high (>80%) in all bioreactors, nitrification was limited due to high organic loading (350–800 mg sCOD L–1), relatively short retention time (24 h), and low dissolved oxygen levels (<3.5 mg O2 L–1). Grow beds showed significant nitrification, indicating the importance of upstream organic removal. CO2 supplementation (0.5% v/v) in bioreactors did not promote nitrification in the bioreactors but was beneficial for nitrification in grow beds due to pH-modulating effects. Microbiological analyses showed no Salmonella detection in bioreactors and substantial reductions in total coliform (∼40%) and aerobic plate counts (∼30%) after UV treatment. These findings demonstrate the sustainable and safe reuse of nutrient-rich industrial effluents in agriculture.
