摘要:
以餐厨垃圾发酵废水为处理对象，构建耐高氨氮的厌氧-好氧生物处理系统，并探究了厌氧（ASBR）-好氧（SBBR）-混凝组合工艺的处理效能。结果表明，接种城镇污水厂的脱水污泥，采用逐步提高氨氮浓度的方式，在温度为（50±1） ℃、进水氨氮浓度为3 600 mg/L的条件下，成功构建耐高氨氮和高温的厌氧生物处理系统，对COD的平均去除率可达到69.5%，系统中的优势水解酸化细菌主要为Lysinibacillus、Coprothermobacter、Sporosarcina等，优势产甲烷古菌为Methanothermobacter。在ASBR系统的有机负荷（以COD计）为1.0 kg/（m3·d）、SBBR系统的DO浓度为6 mg/L、混凝单元中混凝剂FeCl3的投加量为200 mg/L条件下，组合工艺对COD的总去除率可达到94.80%，其中，厌氧、好氧、混凝处理单元对系统去除COD的分担率分别为61.20%、26.93%、6.67%。三维荧光光谱分析结果表明，厌氧和好氧生物处理系统对易生物降解有机物的去除起主导作用，混凝单元对以腐殖酸为主的难降解有机物去除效能显著。
Abstract:
A biological anaerobic-aerobic treatment system with high ammonia nitrogen resistance was constructed for treating fermentation wastewater from food waste, and the treatment performance of the anaerobic (ASBR)-aerobic (SBBR)-coagulation process was investigated. By inoculating dewatered sludge from an urban sewage treatment plant, the anaerobic treatment system with high ammonia nitrogen and high temperature resistance was successfully established under the conditions of temperature of (50±1) ℃ and influent ammonia nitrogen of 3 600 mg/L. The average COD removal efficiency could reach 69.5%. The dominant hydrolytic and acidifying bacteria in the system were Lysinibacillus, Coprothermobacter, Sporosarcina etc., and the dominant methanogenic archaea was Methanothermobacter. Under the circumstances where the organic load (calculated as COD) of the ASBR amounted to 1.0 kg/(m3·d), the DO of the SBBR system was 6 mg/L, and the dosage of the coagulant FeCl3 in the coagulation unit stood at 200 mg/L, the overall COD removal efficiency of the combined process could attain 94.80%. The proportions of COD removal in the anaerobic, aerobic, and coagulation treatment units were 61.20%, 26.93%, and 6.67% respectively. The analysis results of three?dimensional fluorescence spectra indicated that the anaerobic and aerobic treatment system exerted a leading role in the removal of readily biodegradable organic matters, and the coagulation unit exhibited a remarkable removal efficiency for the refractory organic matters dominated by humic acid.
