【摘要】：模擬了氮元素在水、能源、食品、林業(yè)、廢物管理等多部門的代謝流動,以蘇州為例構(gòu)建了元素代謝系統(tǒng)分析模型,識別了氮元素代謝的重要部門和關(guān)鍵環(huán)節(jié),針對性地提出尿源分離、污泥熱解、高溫?zé)峤�、藻類凈水等四種氮回收技術(shù)及組合,分析技術(shù)應(yīng)用對城市氮元素代謝性能的影響.結(jié)果表明:蘇州氮元素從外界輸入160萬t/a,90%來自煤炭和天然氣;能源、食品和水部門是氮回收的關(guān)鍵環(huán)節(jié);四項(xiàng)氮回收技術(shù)組合應(yīng)用可實(shí)現(xiàn)氮元素整體代謝效率提至52%,優(yōu)化調(diào)控效果最好,可促進(jìn)低氮型社會的構(gòu)建.
[Abstract]:The metabolic flow of nitrogen elements in water, energy, food, forestry and waste management was simulated. The analysis model of element metabolism system was constructed in Suzhou, and the important departments and key links of nitrogen metabolism were identified. Four nitrogen recovery techniques including urine source separation, sludge pyrolysis, high temperature pyrolysis and algae water purification were put forward, and the effects of the application of the technology on the metabolic properties of urban nitrogen elements were analyzed. The results show that 90% of nitrogen input from the outside world comes from coal and natural gas, energy, food and water are the key parts of nitrogen recovery. The combined application of four nitrogen recovery technologies can realize the overall metabolic efficiency of nitrogen element to 52. The optimal control effect is the best and can promote the construction of low nitrogen society.
