污泥固化与飞灰固化的背景技术：
Background technology of sludge solidification and fly ash solidification:
随着城镇化进程的发展，环境问题也越来越严峻。污水排放量，城镇生活垃圾产生量不断增加，随之污水处理过程中产生的污泥和垃圾焚烧发电厂产生的飞灰也不断增多。
With the development of urbanization, environmental problems are becoming more and more serious. The amount of sewage discharge and the amount of urban domestic waste are increasing, along with the increasing amount of sludge produced in the process of sewage treatment and fly ash produced by waste incineration power plants.
污泥是指污水处理厂在处理污水后残留下的固态，半固态及液态废弃物，含有大量的有机物和氮磷等营养物，重金属以及致病菌和病原菌等，且常常定网站建设  伺服液位仪  防撞墙模具 唐山护栏 遮阳网 风电基础模具伴有恶臭气体。
Sludge refers to the solid, semi-solid and liquid waste left by the sewage treatment plant after sewage treatment. It contains a large number of nutrients such as organic matter, nitrogen and phosphorus, heavy metals, pathogenic bacteria and pathogens, and is often accompanied by malodorous gas.
目前污泥的处理处置方法有堆肥处理，水体消纳，卫生填埋，焚烧处理和土地利用等，而这些处理方法产生二次污染严重，都无法对污泥进行经济有效的无害化处理及资源化利用。
At present, the treatment and disposal methods of sludge include composting, water consumption, sanitary landfill, incineration and land use. These treatment methods produce serious secondary pollution, which can not carry out economic and effective harmless treatment and resource utilization of sludge
