城市污泥处置不当会对环境造成污染。将城市污泥的处置与资源化相结合,才是城市污泥处置的最优方法。现有的城市污泥处理技术主要有卫生填埋法、厌氧消化法、湿式氧化法、干化焚烧、排海、农用及其他技术手段。在处理过程中,仍然存在臭气、重金属及渗滤液污染、可燃气体爆炸、投资大、运行成本高等问题及风险。需要加强城市污泥高效快速堆肥、污泥制造有机———无机复合肥、污泥制造建筑材料、污泥热能利用等关键技术及设备的研发,推进我国城市污泥高效利用的发展。
城市汙泥處置不噹會對環境造成汙染。將城市汙泥的處置與資源化相結閤,纔是城市汙泥處置的最優方法。現有的城市汙泥處理技術主要有衛生填埋法、厭氧消化法、濕式氧化法、榦化焚燒、排海、農用及其他技術手段。在處理過程中,仍然存在臭氣、重金屬及滲濾液汙染、可燃氣體爆炸、投資大、運行成本高等問題及風險。需要加彊城市汙泥高效快速堆肥、汙泥製造有機———無機複閤肥、汙泥製造建築材料、汙泥熱能利用等關鍵技術及設備的研髮,推進我國城市汙泥高效利用的髮展。

Improper municipal sludge treatment will create pollution to the environment, and a combination of sludge treatment and resource utilization should be the optimal treatment method. The existing methods include sanitary landfill, anaerobic digestion, wet oxidation, incineration, discharging into the sea and agricultural utilization etc. However, there are still problems and risks during the treatment process, that is, contamination caused by odor, heavy metal and leachate, flammable gas explosion, huge investment and high operation cost. Thus, we need to strengthen the research of key technology including rapid and high-efficient composting, production of organic-inorganic compound fertilizer, production of building material and thermal energy utilization as well as related equipments, which could promote the development of municipal sludge efficient utilization in our country.
