摘要:
为给污水处理厂生物脱氮除磷提供新的碳源选择和实现废弃物资源化利用，以工业乙酸钠为对照，研究了以生物燃料生产过程中的副产物（BBP）为碳源的生物脱氮除磷效果。BBP反应器运行19 d后，出水TN、TP浓度与乙酸钠反应器的接近。BBP反应器对TN的去除率可达61.7%，TP去除率约为80%，出水COD维持在50 mg/L以下，出水水质可达到GB 18918—2002的一级A排放标准。BBP中不易被微生物直接利用的有机物占比达42%，乙酸钠中为15%。以BPP对活性污泥进行驯化后，其反硝化潜力从0升至10.63 mgNO3--N/(gVSS·h)，脱氮能力提高，与乙酸钠初期反硝化潜力11.09 mgNO3--N/(gVSS·h)相近。
Abstract:
In order to provide a new choice of carbon source for wastewater treatment plant and realize the utilization of waste resources, using industrial sodium acetate as a control, the biological nitrogen and phosphorus removal of the by-product (BBP) from the biofuels production process was studied. After 19 days of operation in the BBP reactor, the effluent TN and TP concentrations were close to those in the sodium acetate reactor. The removal rate of TN and TP in BBP reactor could reach 61.7% and 80% respectively, the effluent COD concentration was maintained below 50 mg/L, and the effluent quality could meet the first level A discharge standard of GB 18918-2002. In BBP, the proportion of organic matter which was not easy to be directly used by microorganisms was 42%, and that in sodium acetate was 15%. After the domestication of activated sludge using BBP as the carbon source, the denitrification potential increased from 0 to 10.63 mgNO3--N/(gVSS·h), which was close to initial denitrification potential of sodium acetate of 11.09 mgNO3--N/(gVSS·h).
