摘要:山西省晉中市污水處理廠建立了國內(nèi)首家較大規(guī)模的污泥碳化工程項目，處理量達(dá)到300 t/d，取得了良好的處理效果，但其產(chǎn)生的碳化裂解液中COD濃度高達(dá)20 000 mg/L左右、氨氮濃度約為1 200 mg/L，并含有大量難降解有機物，碳化裂解液的處理成為制約該工藝發(fā)展的主要原因。為此，提出了污泥碳化裂解液制備反硝化碳源和產(chǎn)甲烷兩種資源化方案，并構(gòu)建了處理量為1 m3/d的中試裝置。研究結(jié)果表明，通過厭氧產(chǎn)甲烷工藝，裂解液中有機物的甲烷產(chǎn)率達(dá)到0.33 m3/kgCOD，證明其具有較好的產(chǎn)甲烷潛力；通過厭氧酸化聯(lián)合氨吹脫工藝，裂解液中的COD酸化率達(dá)到50%以上、COD損失率為14.2%、氨氮去除率達(dá)到85%以上；裂解液制備的碳源的反硝化效果略低于乙酸鈉但優(yōu)于葡萄糖，是良好的反硝化碳源。以中試結(jié)果和市場價格推算，日產(chǎn)生300 m3裂解液的污泥碳化工程，若回收甲烷每年可節(jié)約能源成本141.99萬元，若回收碳源每年可節(jié)省碳源投加費用467.57萬元。
Abstract:The first large-scale sludge carbonization project in China has been established in a wastewater treatment plant in Jinzhong, Shanxi Province. The project has a treatment capacity of 300 t/d and a good treatment performance. However, the concentrations of COD and ammonia nitrogen in the carbonized pyrolysis liquid are as high as 20 000 mg/L and 1 200 mg/L, and the liquid also contains a lot of refractory organic matters, leading to its treatment becomes the main reason restricting the development of this process. Therefore, two resource utilization schemes were proposed, namely preparation of denitrifying carbon source and methane production from the carbonized pyrolysis liquid, and a pilot plant with a treatment capacity of 1 m3/d was constructed. The methane production rate of the organic compounds in the pyrolysis liquid reached 0.33 m3/kgCOD through the anaerobic methanogenic process, which proved that this liquid had a good methanogenic potential. The COD acidification rate, COD loss rate and ammonia nitrogen removal efficiency in the carbonized pyrolysis liquid reached more than 50%, 14.2% and 85% by the anaerobic acidification combined with ammonia stripping process. The denitrifying performance of the carbon source prepared by the pyrolysis liquid was slightly worse than that of the sodium acetate but better than that of the glucose, indicating that it was a good denitrifying carbon source. According to the results of the pilot test and the price in the market, the sludge carbonization project that produced 300 m3/d pyrolysis liquid could save energy cost of 1.419 9 million yuan per year if methane was recovered, and carbon source consumption cost of 4.675 7 million yuan per year if carbon source was recovered.
