ABR-SBR组合工艺处理养猪场废水研究 总被引:1,自引:0,他引:1
规模化养猪场废水处理量大,有机物浓度大,氨氮、SS含量大,用单一的工艺处理很难达到排放标准,针对于此,采用ABR-SBR组合工艺对猪场废水进行处理,实验结果表明:处理后出水各项指标达到了GB1978-1996的一级畜牧废水排放标准。 相似文献

化学沉淀法去除养猪场废水中氨氮的试验研究 总被引:12,自引:0,他引:12
以Na2HPO4和MgSO4为沉淀剂,先用化学沉淀法处理模拟高浓度氨氮废水,通过正交试验确定影响因素大小,然后用化学沉淀法处理养猪场的高浓度氨氮废水,得出最佳工艺条件:在pH值为10.0、n(Mg):n(N)=1,2、n(P):n(N)-1.02的反应条件下,氨氮去除率达到90%。 相似文献

BACKGROUND: Small‐scale experimental investigations were carried out on the anaerobic digestion of potato processing wastewater and its co‐digestion with pig slurry and/or abattoir wastewater. A simple and rapid procedure was used to determine the suitability of these wastes for digestion. RESULTS: During the initial 5‐day acclimation phase, the seed (digested brewery waste) was replaced by the test waste before allowing the tests to incubate without further addition, where methanogenesis was measured. Although potato processing wastewater has low pH, with high fat content treatment via anaerobic digestion was still feasible in spite of low methane production. Co‐digestion with pig slurry and abattoir wastewater was therefore investigated to enhance the process. Pig slurry improved the process, which, when co‐digested with potato processing wastewater in equal ratio achieved 72% volatile solids removal, 35 mL average daily biogas production and 32% maximum methane content in 22 days (following the acclimation period). Co‐digestion with abattoir wastewater did not improve the digestion process due to poor buffering and low pH value. CONCLUSION: Anaerobic co‐digestion may be a feasible treatment option for industrial bio‐wastes and livestock wastes produced in Cyprus and indeed in similar other countries of comparable market size and activities.
